Buoyancy Lab: Archimedes’ Principle Essay. The objective of acid, this experiment is to expert thesis, use the Archimedes principle to evaluate the specific weight of all of the acid separate materials. This objective of this experiment is nios assignment answers, significant in that it gives valuable information on how to determine the material composition of an object when given very vague information. From information learned in the accompanying Fluid Mechanics lecture course, basic formulas can be applied to solve for the specific weight of the object in question. The experiment performed will involve the coursework buoyancy principle and essays wallpaper, include calculating the volume displaced of a submerged object. This is laboratory experiment under a controlled environment. The results of acid, this experiment can be found by using the weight of each object when dry as well as submerged in water in order to glass analysis, determine the specific weights of the objects.

This concludes the Archimedes principle to be true in that the collected values were very close to those of the available accepted data for the respected materials. These findings will likewise set the basis for fluid mechanics study to come during the remainder of this course. The objective of this lab experiment is to gather enough information to be. able to use the buoyancy principle to determine specific weight of acid, multiple objects. Submarines apply Archimedes’ Principle when changing depth. A submarine dives deeper by opening its ballast tank, collecting enough water to increase the submarine’s weight to an amount greater than the nios assignment answers buoyant force. By pushing water out of the ballast tanks, the submarine becomes lighter than the buoyant force, allowing the submarine to rise.

Archimedes Principle is used in everyday industries which involve buoyancy, to include watercraft, weather balloons, and even life-preservers. It is necessary to know whether or not something will float, as intended, or sink below the surface of the fluid in which it is In the acid year 250 B.C. Greek mathematician Archimedes of glass analysis, Syracuse published On Floating Bodies, a book containing various scientific and mathematical principles which he had scrutinized and eventually proved through rigorous trial and error [1]. While never fully verified, the legend of the acid coursework buoyancy principle was verified by Archimedes himself after noticing the water level rise after stepping into expert thesis his bathtub one night. His exclamation of “Eureka!”, Greek for “I found it” marked this significance and had been used as a verbal mark for discovery in the English language ever since. In modern engineering, Archimedes principle can be seen in nearly every real world application. In the basic sense, calculations for ocean-going vessels are wholly dependent on coursework, the buoyancy principle. For a more broad sense, the principle of material composition verification can nearly always come back to soaking and floating an object. And for a more abstract outlook, the floating of blimps, balloons, and lighter-than-air craft is dependent on the fact that their specific weight is equal to their weight displaced divided by their displaced volume. Nios Assignment! Theory Experimental Methods: Archimedes Principle states that objects in a specific medium (i.e. air or water) experience an upward force known as buoyant force. In order for something to stay afloat, this force must be equal in acid, magnitude or in the case of academic, lift with a hot-air balloon, greater than, the weight of the volume displaced by that object.

Moreover, this amount of substance or in the case of coursework, this experiment; the water (or fluid) displaced will be equal to the volume of water displaced divided by the specific weight of the honesty essays object. Figure 1 illustrates the relationship between weight force and buoyant. force. By performing this experiment, one can evaluate the specific weight of the material by acid coursework, using the submerged weight and the dry weight difference. Figure 1. Honesty Essays! Buoyant Force VS. Weight Force. The student will measure the dry weight of each of the materials provided and then will measure the wet weight of those materials and container. If applicable, the student will also use the submerged height of the object if it is submerged. Wfluid Displaced =?fluid * VD Eqn. (1) FB = WB – WS Eqn. (2) FB = VD *? fluidEqn. (3) Where: FB : Buoyant Force (lb) VD : Volume of coursework, fluid displaced (ft3) WFluid Displaced: Weight of fluid displaced Dry Weight [lb] WD : Dry Weight [lb] Ws : Submerged Weight (lb)? : Specific Weight [lb / ft3] ?fluid: Specific Weight [lb/ft3] Assume that the specific weight of air is negligible and that pressure is at normal atmospheric.

Determine the dry weight of each of the given objects: wood, aluminum, quartz, aluminum cylinder, and streel ball. Measure the submerged weight of each object using the scale. Measure the submerged depth if the object is floating. Find the submerged volume of each object using ?water = 62.4 lb/ft3. For completely submerged objects this is school admissions essay, equal to coursework, the total volume of the object. For floating objects this is just the volume below the liquid surface.

Find the total volume of chiropractic school essay, each object. Calculate the specific weight of each material. Figure 1. Wood Block Sample A. Figure 1. Aluminum Sample B. Figure 3. Aluminum Cylinder Sample. Figure 2. Acid Coursework! Steel Sample B. • Container: used for holding the water which will act as the fluid medium for measurement. •Scale, no preference.

Acid Coursework. routing slip#x2014;Contains information about the flow pattern for the workflow, assignees, escalation policy, expiration duration, signature policy, sequence in which the participants interact in the task, and so on. Features of workflow services include: Standard work queues #x2014; high priority tasks, tasks due soon, new tasks, and so on. Custom work queues #x2014; Users can define new work queues based on research paper, specific search criteria. Acid. Proxy work queues #x2014; can grant access to essays other users to selected work queues. Other users can act on acid coursework, your behalf on those tasks. User rules #x2014; can define custom delegation, auto-approval, or vacation rules. Group rules #x2014; can define auto-assignment rules for roles or groups; for example, round-robin, least-busy, and so on. Task assignment and routing#x2014;includes creating tasks from the business process and assigning the glass tasks to users or roles. Other task assignment and routing features include: Support for task expiration and automatic renewal. Support for task delegation, escalation, and acid, reapproval. Storage of task history information for auditing, extending workflows to include other workflows, and the ability to archive and purge task details based on specified policies. Support for creating custom task escalation rule functions. Override and restrict default system actions. Specify callback classes on task status. JSP-based forms for viewing and updating task details. Dynamic assignment functions. Built-in reports #x2014; Priority reports, productivity reports, cycle time reports, and unattended tasks report. Academic Honesty. Participant types#x2014;consists of single approver, group vote, management chain, sequential list of approvers, FYI assignees, and external routing services. Identity service#x2014;interacts with back-end identity management systems to coursework capture all user information from chiropractic essay, Java AuthoriZatioN (JAZN) and LDAP. The identity service provides role-based access control; you can assign permissions to roles and link an organizational hierarchy to a role model for authorization. You can also do the following: Assign worklist privileges to coursework users, roles, or groups. Maintain user properties such as name, location, phone, fax, and e-mail. Capture organizational hierarchy (reporting structure) and group information. Integrate with standard (for example, LDAP-based) directory services for user and role provisioning. Identity Service for identity service concepts. Send notifications to specified users on specified task changes.

Out-of-the-box productivity reports. 15.2.1 Workflow Functionality: A Procurement Process Example. The functionality of workflow services can be illustrated using a simple order approval business process to approve or reject an order, as shown in Figure 15-2. requested items. Approval and rejection is a two-step process involving an initial approver and the manager of the initial approver. Acid. The order is first assigned to the Supervisor role. Once a user belonging to the Supervisor role approves the order, it is expert thesis sent to this user's manager for final approval. Figure 15-2 BPEL Workflow. Oracle BPEL Process Manager Order Booking Tutorial for instructions on designing an order approval business process to approve or reject an coursework order. 15.2.2 Workflow Services Components. Figure 15-3 shows the following workflow services components: The task service provides task state management and persistence of tasks. In addition to these services, the task service exposes operations to update a task, complete a task, escalate and reassign tasks, and so on. Glass Menagerie Analysis. The task service is used by the Oracle BPEL Worklist Application to retrieve tasks assigned to users. This service also determines if notifications are to be sent to users and acid, groups when the state of the task changes. The task service consists of the following services. Task Routing Service. The task routing service offers services to chiropractic admissions route, escalate, and reassign the task. The service makes these decisions by interpreting a declarative specification in the form of the routing slip. Task Query Service. The task query service queries tasks for a user based on a variety of search criterion such as keyword, category, status, business process, attribute values, history information of a task, and so on. Task Metadata Service. The task metadata service exposes operations to retrieve metadata information related to a task. The identity service is a thin Web service layer on coursework, top of the Oracle Application Server 10 g security infrastructure or any custom user repository. It enables authentication and authorization of users and the lookup of academic honesty essays, user properties, roles, group memberships, and privileges. The notification service delivers notifications with the acid coursework specified content to the specified user to any of the following channels: e-mail, telephone voice message, pager, fax, and chiropractic school essay, SMS. See Notifications from Workflow Services for more information. User Metadata Service. The user metadata service manages metadata related to coursework workflow users, such as user work queues, preferences, vacation, and delegation rules. Runtime config service. The runtime config service provides methods for managing metadata used in about the yellow, the task service run time environment. It principally supports management of task payload flex field mappings. Figure 15-3 Workflow Services Components. Figure 15-4 shows the coursework interactions between the expert thesis services and the business process. Figure 15-4 Workflow Services and Business Process Interactions. 15.3 Use Cases for Workflow Services. Using workflow services is demonstrated in the VacationRequest, AutoLoanDemo, ExpenseRequestApproval, LoanDemoPlus, DocumentReview, HelpDeskServiceRequest, and acid, OrderApproval demos. The following sections describe multiple use cases for workflow services. Internet Citations In A Paper. 15.3.1 Assigning a Task to a User or Role. A vacation request process may start with getting the coursework vacation details from a user and answers, then routing the coursework request to about the yellow wallpaper their manager for approval. User details and the organizational hierarchy can be looked up from a user directory or store. This scenario, shown in Figure 15-5, is described in the OrderApproval sample. Figure 15-5 Assigning Tasks to a User or Role from coursework, a Directory. 15.3.2 Using the expert thesis Various Participant Types. A task can be routed through multiple users with a group vote, management chain, or sequential list of approvers participant type. For example, consider a loan request that is part of the loan approval flow. Acid Coursework. The loan request may first be assigned to a loan agent role. Essays About The Yellow. After a specific loan agent acquires and accepts the loan, the loan may be routed further through multiple levels of management if the coursework loan amount is greater that $100,000. This scenario, shown in Figure 15-6, is chiropractic school admissions essay described in the LoanDemoPlus sample. Figure 15-6 Flow Patterns and acid coursework, Routing Policies. See Participant Types in Workflow Services for the various flow types supported by workflow services. You can use these types as building blocks to nios assignment answers create complex workflows. 15.3.3 Escalation, Expiration, and Delegation. A high-priority task can be assigned to a certain user or role based on the task type. However, if the acid user does not act on it in a certain time, the task may expire and in turn be escalated to the manager for further action. As part of the escalation, you may also notify the users by e-mail, telephone voice message, SMS, pager, or fax. Similarly, a manager may delegate tasks from one reportee to another to balance the load between various task assignees. All tasks defined in BPEL have an associated expiration date. Additionally, you may specify escalation or renewal policies, as shown in Figure 15-7. For example, consider a support call, which is part of the HelpDeskServiceRequest process. A high-priority task may be assigned to a certain user and if the user does not respond in nios assignment, two days, then the task is coursework routed to the manager for about the yellow, further action. Figure 15-7 Escalation and Notification. 15.3.4 Automatic Assignment and Delegation. A user may decide to have another user perform tasks on their behalf. Tasks can be explicitly delegated from the Oracle BPEL Worklist Application or can be automatically delegated. For example, a manager sets up a vacation rule saying that all their high priority tasks are automatically routed to one of their reports while the manager is on coursework, vacation. In some cases, tasks can be routed to expert thesis different individuals based on the content of the task. Another example of automatic routing is to allocate tasks among multiple individuals belonging to a group. For example, a help desk supervisor decides to allocate all tasks for the western region based on a round robin basis or assign tasks to the individual with the lowest number of acid, outstanding tasks (the least busy). Nios Answers. 15.3.5 Work Queues and Proxy Support. It is often required that one user be provided with access to part of another user's worklist. For example, an executive decides to coursework provide access to expense approvals within a certain limit to menagerie their secretary. Work queues allow you to create a custom view to group a subset of tasks in acid coursework, the worklist (say high priority tasks, tasks due in chiropractic school essay, 24 hours, expense approval tasks, and acid coursework, so on). These work queues can then be granted to menagerie analysis essay other users who can then act on the task owner's behalf. For example, in the scenario described above, the executive can create a delegated expense approvals work queue for expenses below $5000. 15.3.6 The Oracle BPEL Worklist Application. Users typically access tasks assigned to them by using the Oracle BPEL Worklist Application, as shown in Figure 15-8. A worklist consists of tasks assigned to the user as well as the groups to which they belong. A task may also include forms and attachments in addition to other task details such as history, comments, and approval sequence. The worklist may also be accessed from OracleAS Portal or other clients to act on tasks as well as get productivity reports. The Oracle BPEL Worklist Application can be customized and extended based on the specific needs of an application. See Chapter 16, Worklist Application for details about worklist functionality and the sample Oracle BPEL Worklist Application. Figure 15-8 Oracle BPEL Worklist Application#x2014;Access Tasks, Forms, Attachments, and Reports. 15.4 Participant Types in Workflow Services. Coursework. Oracle BPEL Process Manager provides a library of participant types (known in previous releases as workflow patterns). You can choose a participant type that meets your business requirement and model your workflow based on the participant type. Oracle BPEL Process Manager supports the following participant types: Single Approver #x2014; used for a single user to you use research paper act on a task. Acid. If the task is assigned to a role or group with multiple users, one of the members must claim the task and expert thesis, act on it. Based on the user's action, you define what the acid business process does. Group Vote #x2014; used when multiple users, working in parallel, must take action simultaneously, such as in a hiring situation when multiple users vote to hire or reject an applicant. You specify the assignment answers voting percentage that is needed for the outcome to take effect, such as a majority vote or a unanimous vote. Management Chain#x2014;used to route tasks for approval to multiple users in a management chain hierarchy. You specify the task participants as a management chain list or a list of acid, users. Essays. Sequential list of approvers (extension of a sequential workflow)#x2014;used to acid create a list of sequential participants for expert thesis, a workflow. Coursework. This type is similar to the management chain participant type, except that with that type, the users are part of an organization hierarchy. For the sequential list of approvers participant type, they can be any list of users or groups. FYI assignee #x2014; used when a task is sent to a user, but the how do paper business process does not wait for a user response; it just continues. FYI assignees cannot directly impact the outcome of a task, but in acid, some cases can provide comments or add attachments. Nios Assignment Answers. External Routing Service #x2014;used to coursework configure an external routing service that dynamically determines the participants in the workflow. If this participant type is specified, all other participant types are ignored. It is assumed that the external routing service provides a list of participant types (single approver, list of chiropractic admissions, approvers, group vote, and so on) at run time to determine the routing of the task. 15.4.1 Continuing Workflows from Other Workflows. Coursework. You can have situations where you need to continue a previous workflow task in expert thesis, the current workflow task. Coursework. Oracle BPEL Process Manager enables you to include the task history, comments, and attachments from the previous task. This provides you with a complete end-to-end audit trail. 15.5 Overview of the Modeling Process. The modeling process consists of creating a human task, associating it with a BPEL process, and generating the format for displaying the human task during run time in the Oracle BPEL Worklist Application. This section provides a brief overview of glass menagerie essay, these modeling tasks and provides references to specific modeling instructions. 15.5.1 Create a Human Task Definition with the Human Task Editor. The Human Task editor enables you to define the metadata for the task. This editor enables you to acid coursework specify human task settings, such as task outcome, payload structure, task participants, assignment and routing policy, expiration and escalation policy, notification settings, and so on. This information is nios assignment answers saved to a metadata task configuration file with a .task extension. 15.5.2 Associate the acid Human Task Definition with a BPEL Process. You associate the .task file that consists of the human task settings with a BPEL process. Association is made with a human task activity that you drag and drop into your BPEL process for configuring. You also define the task definition, task initiator, task priority, and school admissions essay, map the acid coursework task parameter that carries the input data to a BPEL variable. You can also define advanced features, such as the scope and essays about, global task variables names (instead of accepting the default names), task owner, identification key, BPEL callback customizations, and whether to extend the human task to include other workflow tasks. When association is coursework complete, a Task Service partner link is created. The Task Service exposes the operations required to act on chiropractic admissions essay, the task. 15.5.3 Generate the Task Display Form. You generate the layout of the task display form used for displaying the task header, body (task payload), and footer details at run time in Oracle BPEL Worklist Application. The task display form defines the display mechanism for the task payload (data in the task) in the Oracle BPEL Worklist Application. Two types of task display forms are available for acid, use: simple task form and custom task form. 15.6 Task 1: Creating the Human Task Definition with the Human Task Editor. The Human Task editor enables you to define the metadata for the task. This editor enables you to specify human task settings, such as task outcome, payload structure, task participants, assignment and routing policy, expiration and escalation policy, notification settings, and so on. When human task creation is complete, the following folder and nios, file are created: A folder with the human task name you specify in acid coursework, the Human Task Name field in Accessing the Human Task Editor is created under the Integration Content folder of your BPEL process in academic essays, the Application Navigator. The human task settings specified in the Human Task editor are saved to a metadata task configuration file with a .task extension. This file is acid coursework stored in the human task name folder. You can re-edit the settings in this file at menagerie any time by double-clicking it in the Application Navigator . This reopens the .task file in the Human Task editor. This section contains the following topics: 15.6.1 Accessing the Human Task Editor. When you are ready to acid begin creation of a human task, the Human Task editor can be accessed in several ways in Oracle JDeveloper: 15.6.1.1 From the Application Navigator.

Click Yes when prompted to update your human task definition to account for the custom outcomes. Open the acid switch activity of the human task activity and note that the custom outcomes now appear. Or, always create human task definition files as follows: Right-click the BPEL process in the A pplication Navigator . Select Create Human Task Definition . Design a human task definition. Drag a new human task activity into the design window and associate it with this human task definition file. Open the switch activity of the human task activity and note that the custom outcomes appear. The task owner can view the tasks belonging to business processes they own and perform operations on analysis, behalf of any of the coursework assigned task participant types. Additionally, the owner can also reassign, withdraw, or escalate tasks. This optional field defaults to the system user bpeladmin if not specified. The task owner can also be specified in the Advanced tab of the Human Task window described in Specifying a Task Owner. The task owner specified in the Advanced tab overrides any task owner you enter here. Select a method for specifying the task owner: 15.6.3.3.1 Specifying a Task Owner By Browsing the essay User Directory. Task owners can be selected by browsing the acid coursework user directory (Oracle Internet Directory (OID), JAZN/XML, LDAP, and so on) that is configured for use with Oracle BPEL Process Manager. Click the first icon to the right of the Owner field to display the Identity lookup dialog. Search for the owner by entering a search string such as jcooper, j*, *, and so on. Clicking Lookup fetches all the expert thesis users that match the search criteria. One or more users or groups can be highlighted and selected by clicking Select .

Click OK to return to the Human Task editor. Your selection displays in the Parameters section. If you want to edit your selection, highlight it and click the first icon in coursework, the upper right part of the Parameters section. Figure 15-12 shows the Assignment and expert thesis, Routing Policy section of the Human Task editor. This section enables you to select a participant type that meets your business requirement. In previous Oracle BPEL Process Manager releases, participant types were known as workflow patterns. You can mix and match multiple participant types to coursework model the wallpaper human task. This enables you to extend the functionality of a previously configured human task to model more complex workflows. Each of the participant types has an associated editor that you use for configuration tasks. The sequence in which the assignees are added indicates the execution sequence. Figure 15-12 Human Task Editor #x2014; Assignment and Routing Policy Section. Acid Coursework. Click the + sign to display the essay Add Participant Type window. This enables you to select a specific participant type. Select a participant type from the acid Type list. The configuration tasks for each participant type are described in subsequent sections. See the following section based on your selection: Sequential list of approvers. External routing service. See the following task assignment and routing policy sections shown in Figure 15-12 after you have configured a participant type. Analysis. These sections are only available for selection after a participant type has been created. Users and groups for each of the participant types can be specified either statically or dynamically.When the users and groups are specified statically (or by browsing the identity service), the values can be either of the following: A single user or group (for example, jstein ), which in coursework, the case of a single approver, is captured as follows: A delimited string of users or groups (for example, jstein , wfaulk , cdickens ), which in the case of a single approver, is chiropractic essay captured as follows: You may have a business requirement to create a dynamic list of task approvers specified in a payload variable. This XPath expression can resolve to zero or more XML nodes. Coursework. Each node value can be either of the following: A single user or group. A delimited string of assignment answers, users or groups. For example, the following task shows that the coursework payload message attribute is essays the yellow of type xsd:String and coursework, its value is a comma-delimited string of approvers. This node can be used to specify the participants. The default delimiter for assignment, the assignee delimited string is a comma ( , ). This delimiter can be changed using the coursework assigneeDelimiter XML element in the wf-config.xml file. This delimiter applies to all workflows in the system. Specifying participants in nios, this manner is applicable to all participant types, although they are interpreted differently for each type. For example: In a single user participant type, the task is assigned to everyone evaluated. In a sequential list of approvers participant type, the task is sequentially assigned to users and groups evaluated in the list. In a group vote participant type, a task is created for each user and group evaluated in the list. Acid. This interpretation of resource XPath expressions provides orcl:create-nodeset-from-delimited-string -equivalent functionality to enable you to specify a dynamic list of one or more task approvers (resource element members) from the payload variable. 15.6.5.2 Configuring the menagerie analysis Single Approver Participant Type. Figure 15-13 displays the Single Approver window. This participant type requires a single user to act on a task. If the coursework task is essays assigned to coursework a role or group with multiple users, one of the members must claim the task and act on it. Based on the user's action, you define what the business process does. Chiropractic Essay. For example, a vacation request is assigned to a manager. The manager must act on the request task three days before the vacation starts. If the acid coursework manager formally approves or rejects the request, the employee is notified with the decision. If the manager does not act on the task, the about the yellow request is treated as rejected. Notification actions similar to the formal rejection are taken. Figure 15-13 Add Participant Type #x2014; Single Approver. Enter a recognizable label for this participant in acid, the Label field. This label must be unique within this workflow (for example, Approval Manager , Primary Reviewers , and expert thesis, so on). Instructions for acid coursework, configuring the academic honesty essays following subsections of the Add Participant Type - Single Approver window are listed in Table 15-3: Table 15-3 Add Participant Type #x2014; Single Approver. 15.6.5.2.1 Assigning Participants to the Single Approver Task. Select a method for assigning a user or group to participate in performing actions on this task. Acid Coursework. Enter a user or group name or click the first icon ( flashlight ) to the right of the honesty essays field to display a window for selecting a user or group configured through the identity service. The identity service enables user authorization and the lookup of coursework, user properties, roles, group memberships, and privileges. User information is obtained from chiropractic admissions essay, Java AuthoriZatioN (JAZN) or an LDAP server such as Oracle Internet Directory. Acid. You can use wild cards (*) to search for IDs. Dynamically assign this task to a user (for example, jcooper ) or group (for example, administrators ) by clicking the icon to the right of the field to display the Expression Builder window. Users who are members of a group are assigned this task. For a user to chiropractic school admissions act on a task assigned to a group, they must first claim the task in the Oracle BPEL Worklist Application during run time. The XPath expressions for specifying assignees must follow these rules: They must be based off the task XSD. This includes the payload as defined in the payload section. For example, /task:task/task:payload/order:orderAssignee is an example of an XPath expression based of the task XSD. The XPath expressions cannot contain BPEL-specific XPath functions such as bpws:getVariableData() , and so on because these XPath expressions are not evaluated from the context of a BPEL instance. The XPath expressions can contain XPath functions that are BPEL-independent. Acid. This includes identity service XPath functions like ids:getManager() , and so on. Expert Thesis. 15.6.5.2.2 Bypassing a Task Participant. Select the Specify skip rule check box if you want the user or group to be bypassed if a specific condition is satisfied. This action displays an icon for accessing the Expression Builder window for building a condition. For example, if a user submits a business trip expense report that is below a specific amount, no approval is required by their manager. Coursework. The expression to assignment answers bypass a task participant must evaluate to a Boolean value. For example, /task:task/task:payload/order:orderAmount 1000 is a valid XPath expression for acid, skipping a participant. 15.6.5.2.3 Specifying a Time Limit for expert thesis, Acting on a Task. Click the + sign to expand the Advanced section shown in Figure 15-13. Select Limit allocated duration to . Specify the amount of time a user or group receives to act on a task. Acid Coursework. If the user or group does not act in the time specified, the global escalation and renewal policies that you set in the Expiration and Escalation Policy section (known as the routing slip level) of the Human Task editor are applied. For example, if the global policy is set to escalate the task and this participant does not act in the duration provided, the task is escalated to the manager or another user, as appropriate. Escalating, Renewing, or Ending the Task for instructions on setting the global escalation and renewal policies in the Expiration and Escalation Policy section of the you use internet in a paper Human Task editor. 15.6.5.2.4 Inviting Additional Participants to a Task. Coursework. Click the + sign to expand the Advanced section (if not already expanded). How Do Citations. Select the Allow this participant to invite other participants check box if you want this task assignee to invite other participants into the workflow before routing it to the next assignee in this workflow. For example, assume the acid coursework approval workflow goes from James Cooper to John Steinbeck. Academic Essays. If this option is checked, James Cooper can decide to first route it to coursework Irving Stone before it goes to John Steinbeck. 15.6.5.3 Configuring the Group Vote Participant Type. Figure 15-14 displays the Group Vote window. This participant type is used when multiple users, working in parallel, must take action simultaneously, such as in a hiring situation when multiple users vote to hire or reject an applicant. You specify the voting percentage that is needed for the outcome to take effect, such as a majority vote or a unanimous vote. For example, a business process collects the feedback from all interviewers in the hiring process, consolidates it, and assigns a hire or reject request to each of the essays interviewers. At the end, the acid candidate is hired if the research paper majority of interviewers vote for hiring instead of rejecting. Figure 15-14 Add Participant Type #x2014; Group Vote.

If expiration duration is specified at coursework the routing slip level instead of at the participant type level, then this duration is the expiration duration of the task across all the participants. About The Yellow Wallpaper. However, if you specify expiration duration at acid the participant type level (through the Limit allocated duration to field), then those settings take precedence over settings specified in essays about wallpaper, the Expiration and Escalation Policy section (routing slip level). Figure 15-20 Human Task Editor #x2014; Expiration and Escalation Policy Section. 15.6.6.1 Overview or Escalation and Expiration Policy. This section provides an overview of how specifying the expiration duration at this level makes this setting the expiration duration of the task across all the participants. For example, participant LoanAgentGroup and participant Supervisor have 3 days to act on the task between them, as shown in Figure 15-21: Figure 15-21 Expire After Policy. If there is no expiration specified at either the participant level or this routing slip level, then that task has no expiration duration. If expiration duration is coursework specified at any of the participant's level, then for that participant the participant expiration duration is used. However, the global expiration duration is still used for the participants that do not have participant level expiration duration. The global expiration duration is always decremented by the time elapsed in honesty, the task. The policy to coursework interpret the participant level expiration for the participants is honesty essays described below: Management Chain #x2014; Each participant in the management chain gets the same expiration duration. The duration is not for all the assignments resulting from this assignment. If the acid coursework task expires at any of the you use internet citations in a research assignments in acid coursework, the management chain, the academic honesty task expires and the escalation and renewal policy is applied. Sequential list of approvers #x2014; Each assignment in the management chain gets the same expiration duration as the one specified in the sequential list of approvers. Note that the duration is acid coursework not for all the assignments resulting from this assignment. If the task expires at any of the assignments in the management chain, the task expires and the escalation and renewal policy is applied. In a group vote workflow, if the parallel participants are specified as a resource, a routing slip is created for each of the resources. The expiration duration of each created routing slip follows these rules: The expiration duration is the same as the expiration duration of the parallel participant if it has an expiration duration specified. The expiration duration that is left on the task if it was specified at the routing slip level. Academic Essays. No expiration duration, otherwise. If parallel participants are specified as routing slips, then the expiration duration for the parallel participants are determined by acid the routing slip. When the parent task expires in a parallel task, the subtasks are withdrawn if those tasks have not expired or completed. In the following routing slip sample, participant Loan Agent Group has an expiration duration of 1 day and participant Loan Agent Supervisor does not have any expiration duration on expert thesis, the task, even though an expiration duration is coursework specified at the routing slip level. In this example, the routing slip is treated just as if there were no expiration duration specified at the routing slip level. Table 15-8 demonstrates the expiration policy. Note that the management chain in the above example evaluates to two users #x2014; wfaulk and assignment, cdickens (manager of wfaulk ). Table 15-8 Expiration Policy. Select an escalation and expiration policy. You can enter a fixed time or a dynamic time by clicking the icon to the right of the By Expression field to display the acid coursework Expression Builder window.

Specify the maximum time period for the task to how do you use citations in a research paper remain open. When the task expires, either the escalation policy or the renewal policy at the routing slip level is applied. If neither is specified, the task expires. The expiration policy at the routing slip level is common to coursework all the participants. The expiration policy for parallel participants is interpreted as follows. If parallel participants are specified as resources in parallel elements, there is no expiration policy for each of those participants. If parallel participants are specified as routing slips, then the expiration policy for the routing slip applies to the parallel participants. Figure 15-22 indicates that the task expires in 3 days. Figure 15-22 Expire After Policy. If you want to extend the expiration period when the user does not respond within the allotted time, select Renew after from the list shown in Figure 15-20. Specify the maximum number of times to continue renewing this task. The renewal policy specifies the number of times the task can be renewed on expiration and the renewal duration. In Figure 15-23, when the chiropractic essay task expires, it is renewed at most 3 times. It does not matter if the task expired at the LoanAgentGroup participant or the Supervisor participant.

The following system actions can be restricted by unselecting them: Suspend #x2014; Enables task owners (or users with the BPMWorkflowSuspend privilege) to put a workflow temporarily on hold. Task expiration and escalation do not apply until the workflow is acid coursework resumed. No actions are permitted on a suspended task (except resume and withdraw). Push back #x2014; Sends the task one level back in the workflow. For example, assume the chiropractic task was routed to the LoanAgentGroup and then to jstein . If jstein now pushes the task back, it goes back to the LoanAgentGroup. Renew #x2014; If a task is about to expire, a task assignee can renew the task and acid coursework, request more time to perform the task. This operation is not allowed if the process designer has restricted task renewal on the workflow. Skip current assignment #x2014; Skips the current assignment and moves to the next assignment or picks the outcome as set by the previous approver if there are no more assignees. Nios Assignment Answers. Adhoc Route #x2014; Enables a user to enter an outcome and then route the task in an adhoc fashion to the next user who must review the acid coursework task. Request Information #x2014; Any workflow participant can request information from the task initiator or any of the prior approvers of the task. When the requested information is submitted, the task is assigned to essays the yellow wallpaper the user who requested the information. Delegate #x2014; Any workflow participant can delegate the task to another user. In this case, the other user is acting on behalf of the acid current assignee. When the task is delegated, it resides on both users' worklists until the original assignee or the delegated person acts on it. Reassign #x2014; Enables the essay current assignee of the task to coursework transfer it to another user or group. In this case, the task is essays the yellow moved from the worklist of the current assignee to the new assignee. Escalate #x2014; Escalates a task to their manager for further action. Withdraw #x2014; Enables the task initiator to withdraw any pending task if they no longer want to acid coursework send it through the workflow. A task owner can also withdraw a task on behalf of the initiator. When a task is withdrawn, the honesty business process is called back with the state attribute of the task set to Withdrawn . Click OK to return to the Human Task editor. 15.6.8.6 Overriding Default Exception Management. Tasks can error due to acid incorrect assignments. Incorrect assignments can occur for any of the following reasons: Invalid assignees #x2014; The task assignee user or group is assignment not a valid user in the system. Invalid dynamic assignment #x2014; When assignees are specified to acid coursework be dynamic, the dynamic XPath expression is chiropractic admissions not evaluated. In the above cases, the coursework task is marked as errored. By default, the life cycle of the task is completed with that action.During modeling of workflow tasks, you can specify error assignees for the workflow. If error assignees are specified, they are evaluated and the task is assigned to them. The error assignee can perform one of the following actions: Adhoc route #x2014; route the task to the actual users assigned to the task. Glass Essay. Adhoc route allows the task to be routed to users in sequence, parallel, and acid, so on. Reassign #x2014; reassign the academic task to the actual users assigned to acid this task.

If you click the X sign, select Yes when prompted to save your changes. 15.7 Task 2: Associating the Human Task with a BPEL Process. You must associate the .task file that consists of the human task settings with a BPEL process. When association is complete, a Task Service partner link is created. The Task Service exposes the operations required to act on a task. The method by which you created the human task indicates if the acid coursework task is already associated with a BPEL process. Table 15-11 describes these methods and academic essays, references sections on how to proceed. Note that regardless of whether you have already associated the human task with a BPEL process, you must still define key human task activity properties, including the task title, task initiator, task priority, and task parameter variables. These tasks are described in acid coursework, Defining the assignment answers Human Task Activity Title, Initiator, Priority, and Parameter Variables and coursework, Defining the Human Task Activity Advanced Features.

Figure 15-27 Human Task #x2014; General Tab. The General tab of the chiropractic school essay Human Task activity enables you to perform the tasks shown in Table 15-12: Table 15-12 Human Task - General Tab. Enter the task title in coursework, the Task Title field through one of the following methods. This is a mandatory field. Your entry in this field overrides the task title you entered in the Title field of the Human Task editor described in Specifying a Task Title and Priority. The title displays the task in internet citations, the Oracle BPEL Worklist Application during run time. Enter the title manually. Click the icon to the right of the field to display the Expression Builder window to dynamically create the title. You can also mix static text and dynamic expressions in the same title. To include dynamic text, place your cursor at the appropriate point in the text and click the icon on the right to invoke the Expression Builder window. 15.7.3.2 Specifying the Task Initiator and Task Priority. Enter the coursework initiator (for example, jcooper ) or click the icon to the right of the Initiator field to display the Expression Builder window for dynamically specifying an chiropractic school admissions essay initiator. This field is optional. The initiator is the user who initiates a task. The initiator can view their created tasks from the Oracle BPEL Worklist Application and perform specific tasks defined in the System Action Details window, such as withdrawing or suspending a task. If not specified, the initiator defaults to coursework the task owner specified on the Advanced tab of the honesty Human Task window. The initiator defaults to bpeladmin if a task owner is also not specified. Select a priority value between 1 (the highest) and 5 from the Priority list. This field is provided for user reference and acid, does not make this task a higher priority during run time. The priority can be used to sort tasks in menagerie, the Oracle BPEL Worklist Application. This priority value overrides the priority value you select in the Priority list of the Human Task editor. Specifying a Task Title and Priority for instructions on specifying the acid priority in the Human Task editor. The task parameter table displays a list of task parameters after you complete the Task Title and Initiator fields. Click the flashlight in the BPEL Variable column to map the task parameter to the BPEL variable. Menagerie Analysis. You must map only the task parameters that carry input data. For output data that is filled in from the worklist, you do not need to map the corresponding variables. The Task Parameters window appears. Acid Coursework. Expand the Variables navigation tree and school essay, select the appropriate task variable. The Human Task window appears as follows. If you want to define advanced features for the human task activity, click the acid Advanced tab and go to section Defining the Human Task Activity Advanced Features. Otherwise, click OK to close the Human Task window. 15.7.4 Defining the Human Task Activity Advanced Features. Figure 15-28 shows the Advanced tab. Figure 15-28 Human Task #x2014; Advanced Tab. The Advanced tab of the Human Task activity enables you to perform the tasks shown in Table 15-13: Table 15-13 Human Task - Advanced Tab. Global Task Variable Name. 15.7.4.1 Specifying a Scope Name and a Global Task Variable Name. You are automatically provided with default scope and global task variable names during human task activity creation. However, you can specify custom names that are used to name the scope and global variable during human task activity creation. Enter the name for expert thesis, the BPEL scope to be generated in acid, the Scope Name field. This BPEL scope encapsulates the entire interaction with the workflow service and BPEL variable manipulation. Enter the global task variable name in the Global Task Variable Name field. Honesty. This is the name of the BPEL task variable used for the workflow interaction. Enter the task owner name in the Owner field or click the icon to the right to use the Expression Builder to dynamically specify the acid owner of this task. The task owner can view tasks belonging to business processes they own and perform operations on behalf of any of the task assignees. How Do Research. Additionally, the owner can also reassign, withdraw, or escalate tasks. If you do not specify a task initiator on the General tab of the acid coursework Human Task window, it defaults to the owner specified here. If an owner is not specified, it defaults to the bpeladmin administrator. 15.7.4.3 Specifying an Identification Key. Enter an nios assignment optional identification key value in coursework, the Identification Key field. The identification key can be used as a user-defined ID for the task. For example, if the task is meant for approving a purchase order, the purchase order ID can be set as the assignment identification key of the task. Tasks can be searched from the Oracle BPEL Worklist Application using the identification key. This attribute has no default value. Acid. 15.7.4.4 Including the Task History of Other Human Tasks. This feature enables one workflow to be continued with another workflow. Select the Include task history from check box to extend a previous workflow task in the BPEL process. Selecting this check box includes the task history, comments, and chiropractic essay, attachments from the previous task. This provides you with a complete end-to-end audit trail. When a workflow task is acid continued with another workflow, the following information is assignment answers carried over to coursework the new workflow: Task payload and chiropractic school admissions, the changes made to the payload in the previous workflow. Comments added to the task in the previous workflow. Attachments added to the task in acid, the previous workflow. Nios Answers. In the Include task history from list, all existing workflows are listed. Selecting a particular workflow permits you to extend (continue) the selected workflow. For example, a hiring process is used to hire new employees. Each interviewer votes to hire or not hire a candidate. If 75% of the acid coursework votes are to hire, then the candidate is hired; otherwise, the candidate is rejected. If the candidate is to be hired, an entry in the HR database is created and the human resources contact completes the assignment hiring process. The HR contact also needs to see the interviewers and the comments they made about the candidate. This process can be modeled using a group vote for the hiring. If the candidate is hired, a database adapter is used to create the entry in the HR database. After this, a simple workflow can include the acid coursework task history from the group vote so that the hiring request, history, and interviewer comments are carried over. This simple workflow is assigned to the HR contact. 15.7.4.5 Allowing Task and nios, Routing Customizations in BPEL Callbacks. Select the Allow task and routing customizations in acid, BPEL callbacks check box to notify the BPEL process using OnMessage callbacks every time a task is routed to a different user or when the task status changes. You must also select the essays about wallpaper check box of the same name in the Advanced Settings section of the Human Task editor shown in coursework, Figure 15-26 in order to update the metadata for callbacks. In these callbacks, you can call the expert thesis Task Service to change the routing or update the current assignees. This option impacts the BPEL code generated to interact with the Task Service. Acid. If this option is not selected, the answers client process gets notified only when the task completes or when it expires or errors out. Click OK to close the Human Task window. Go to the Human Task editor for acid coursework, this human task (the .task file). Expand the Advanced Settings section at the bottom of the editor. Click Allow task and routing customization in glass menagerie, BPEL callbacks . Acid. This check box must be selected to use callbacks. This enables you to update the metadata. Essays. 15.7.5 Viewing the Generated Human Task Activity. When you have completed modeling the human task activity, the human task is generated in the designer window. Figure 15-29 shows how a workflow interaction is modeled in Oracle BPEL Process Manager. Figure 15-29 also illustrates the acid interaction when no BPEL callbacks are modeled. In this case, once a task is complete, the BPEL process is called back with the completed task. No intermediary events are propagated to the BPEL process instance. It is recommended that any user customizations be done in the first assign, AssignTaskAttributes, and that AssignSystemTaskAttributes not be changed. Figure 15-29 Workflow Interaction Modeling. Figure 15-30 shows a workflow interaction in Oracle JDeveloper. Figure 15-30 Workflow Interaction Modeling in school admissions essay, Oracle JDeveloper. If intermediary events need to be propagated to the BPEL process instance, select the Allow task and coursework, routing customization in BPEL callbacks check box in both the essays about the yellow Advanced tab of the Human Task window and the Advanced Settings section of the Human Task editor. When these options are selected, the workflow service invokes callbacks in the BPEL instance during each update of the task. The callbacks are listed in the TaskService.wsdl file and acid, described below: onTaskCompleted #x2014; This callback is invoked when the task is expert thesis completed, expired, withdrawn, or errored. Coursework. onTaskAssigned #x2014; This callback is invoked when the task is assigned to a new set of assignees due to the following actions: Skip current assignment. Override routing slip. onTaskUpdated #x2014; This callback is invoked for any other update to the task that does not fall in the onTaskComplete or onTaskAssigned callback. This includes updates on tasks due to request for information, submit information, escalation, reassign, and so on. onSubTaskUpdated #x2014; This callback is invoked for any update to a subtask. How Do Internet In A Research. Figure 15-31 shows how a workflow interaction with callbacks is modeled in Oracle BPEL Process Manager. Acid Coursework. Once this task is initiated, a while loop is used to receive messages until the task is you use research paper complete. The while loop contains a pick with four onMessage branches #x2014; one for each of the above-mentioned callback operations. The workflow interaction works fine even if nothing is changed in the onMessage branches, meaning that customizations in the onMessage branches are not required. In this scenario, a workflow context is captured in the BPEL instance. This context can be used for all interaction with the workflow services. For example, if you want to reassign a task if it is assigned to a group, then you need the workflow context for the reassignTask operation on the Task Service. Acid. It is recommended that any user customizations be done in the first assign, AssignTaskAttributes, and that AssignSystemTaskAttributes not be changed. Figure 15-31 Workflow Interaction Modeling (with Callbacks) Figure 15-32 shows a workflow interaction in Oracle JDeveloper. Expert Thesis. Figure 15-32 Workflow Interaction Modeling (with Callbacks) in acid coursework, Oracle JDeveloper. 15.7.5.2 Including the Task History from Other Workflows. When the task history is about wallpaper included in a workflow, the generated BPEL process described in the previous two sections is similar, with the following differences: The BPEL variable from the workflow whose task history is to be included is reused and no new BPEL variable is created. The first invoke activity invokes the reinitiate operation instead of the acid initiate operation. In many cases, the outcome of a task determines the flow of the business process. To facilitate modeling of the business logic, when a user task is generated, a BPEL switch activity is also generated with prebuilt BPEL case activities. By default, one case branch is created for each outcome selected during creation of the task. An otherwise branch is also generated in the switch to represent cases when the task is withdrawn, expired, or errored. The task carries a payload in it. If the payload is set from a business process variable, then an assign activity with the name copyPayloadFromTask is created in each of the case and otherwise branches to copy the payload from the task back to its source. If the payload is expressed as other XPath expressions (such as ora:getNodes(. Essays. ) ), then this assign is not created because of the lack of a process variable to copy the payload back. If the acid payload does not need to be modified, then this assign can be removed. 15.7.6.2 Case Statements for Other Task Conclusions. By default, the switch activity contains case statements for the outcomes only. The other task conclusions are captured in the otherwise branch. These conclusions are as follows: The task is glass essay withdrawn. The task is errored. The task is expired. If business logic must be added for each of these other conclusions, then case statements can be added for each of the preceding conditions. The case statements can be created as shown in the following BPEL segment. The XPath conditions for the other conclusions in the case activities for each of the preceding cases are shown in bold. Acid. 15.8 Task 3: Generating the Task Display Form. Expert Thesis. The task display form defines the display mechanism for the task payload in acid, the Oracle BPEL Worklist Application. This section describes the different types of task display forms you can use. This section contains the following topics: 15.8.1 Overview of Task Display Forms. The task display form for the human task can be automatically generated and then customized or developed completely from the beginning using the workflow APIs. In the automatically generated case, a set of seeded templates and regions are used for the task forms. There are two methods for generating forms associated with the how do internet citations in a paper task definition: Automatically generate a simple task form #x2014; JSP-based forms that use the standard header, body, and coursework, footer template. Custom task form #x2014; enables you to select one of the existing templates and regions to create a task form. You can also specify which task parameters to display in the form. When task display forms are generated, a .tform file is created, which includes a template URI and region information. The .tform file is included in the process deployment archive and is deployed during process deployment. 15.8.2 Selecting a Task Display Form. Follow these instructions to generate a task display form for the human task. Go to the Application Navigator in Oracle JDeveloper. Right-click the folder of the human task for which to create a task display form (for this example, ExpenseApproval of the ExpenseRequest BPEL process in selected). The following menu of selections appears. See the following sections for details about generating the expert thesis different types of task forms: 15.8.2.1 Preview Release of acid, Task Display Form Support for ADF Data Controls. A preview release of task display form support for application development framework (ADF) data controls is provided. Very minimal support is provided with this preview release. Essays. Note the following limitations: There is no support for complex XSDs with recursive elements. Task forms generated with ADF data controls cannot be edited. Follow these procedures to use this preview release: Open an acid coursework operating system command prompt. Open Oracle JDeveloper in preview mode: Note that Auto Generate Task Form With ADF Datacontrols now appears as a menu option when you right-click the folder of the answers human task, as shown in acid coursework, Step 2 of Selecting a Task Display Form. Essays. Open the SOA_Oracle_Home j2ee OC4J_Home configserver.xml file. Acid Coursework. where OC4J_Home is the glass name of the OC4J container for your install type: home #x2014; for the Oracle Application Server SOA Basic install type. OC4J_SOA #x2014; if you accepted the acid coursework default value for the Oracle Application Server SOA Advanced install types. Add the following line under the shared-library name=oracle.bpel.common version=10.1.3 section: Restart Oracle Application Server SOA Suite for the changes to take effect. 15.8.3 Automatically Generating a Simple Task Display Form. This option enables you to automatically generate a task form based on the default task parameters and three regions. Chiropractic School Admissions Essay. Select Auto Generate Simple Task Form from the list shown in Step 2. Acid Coursework. The default layout is based on the following three region template: Header region #x2014; this region has standard task attributes such as title, priority, created date, assignee, and expiration date. This information is contained in school admissions essay, the Header1.jsp file. Body region #x2014; this region is generated based on the task parameters. Depending on the XSD used in the task, it is either generated as a list of coursework, values or as a table (for repeating items). If you specified the parameter to be modifiable through the worklist on the Add Task Parameter window in Step 2, it displays as an editable field in the form. Otherwise, the field displays as read-only. About The Yellow. The information for coursework, this region is contained in the payload-body.jsp file and the payload-body.xml mapping file. After generation, if you want to change any read-only parameters, you can modify the payload-body.xml file. Footer region #x2014; this region has an area for comments, attachments, and a short history of the task routing. Glass Analysis Essay. This information is contained in the Footer1.jsp file. A .tform file is generated. The contents of this file are as follows: 15.8.3.1 Payload File for the Autogenerated JSP. Acid Coursework. Two files are automatically generated to display the payload for the autogenerated JSP: A default JSP file named payload-body.jsp . This file is added to the HTML root directory of your project, which is by academic honesty essays default the public_html directory. Acid. A mapping XML file named payload-body.xml . This file is added to the same directory of your project as payload-body.jsp. If you select Custom Task Form in admissions, Step 2, you can specify a unique file name for coursework, the autogenerated JSP. The mapping XML file is created based on the JSP file name. You can also select the payload elements to include in the autogenerated JSP. For example, if the JSP file is named autogenerate-body.jsp , then the mapping XML file is named autogenerate-body.xml . The JSP run-time library and the BPMWorkflow library are automatically added to your BPEL project for compilation of the chiropractic school admissions JSP file. The default JSP is designed with two goals in mind: To present you with a simple form; that is, an XSD tree with a depth of more than three must be shown in acid coursework, a more readable way in the JSP. The default JSP must require minimum modification. The Yellow. If modification is unavoidable, it can be easily performed with a user interface tool. To attain these goals, instead of presenting a tree structure that mimics the payload XSD structure, the default JSP groups the entire payload structure in sections. It groups simple types that belong to the same parents and makes them sections. For example, assume you provide the following payload XSD: This XSD has the structure shown in coursework, Figure 15-33. Figure 15-33 Structure of the XSD for myCompanyType. In the default JSP, based on the structure of the leaf nodes, there are three sections: , , and . Answers. These three sections are named according to their parents' names; that is, the acid sections are named board , my Company , and department , respectively. In the board section, there are two fields, size and head . Each of these fields are in academic essays, an editable HTML input type.The section department is different from other sections and can have multiple occurrences ( maxOccurs 1 ). In this case, all the fields in this section (that is, size , head , and function ) are horizontally presented in a table, with each row representing one department . This is called a table section. There is acid coursework a plus ( + ) button for expert thesis, adding a row (department) and a minus ( - ) button for subtracting a row (department) for the department table section.Unlike a regular section, it is not necessarily true that all the fields belong to the same XSD parent in a table section. For example, suppose the head element has two elements: employeeNumber and dateOfBirth . Since these two elements have maxOccurs set to less than or equal to 1 , they are shown in the same department table section. This is a desired behavior, because adding a row in the department table not only adds a size and a function field, but also adds the head information fields in the same department row. Coursework. This makes it easy to move through complicated payload instances. Nested multiple ( maxOccurs 1 ) elements are supported. Assume the department element has a groupMember child element whose maxOccurs is unbounded. In that case, the parent element department is presented in a table section while the child groupMember elements are presented in expert thesis, different child table sections. The parent department table section has a column called group member that contains an HTML href link pointing to its corresponding child group member section in coursework, each department row. Pressing the + button in the parent department section not only adds a row in the parent table, but also adds a child section for that corresponding new row. The default JSP in the current release has the following limitations: XSDs that contain recursive elements are not supported. The default JSP shows all the expert thesis simple types defined in acid, the payload XSD. If multiple simple types belong to the same XSD choice block, all these simple types are shown in how do you use research, the default JSP. Although simple types are preserved in the JSP, XSD restrictions are not relevant. Only payloads copied from acid coursework, variables that are not simple types are supported. For example, if the query is bpws:getVariableData(var) or bpws:getVariableData(var, part) and the variable is a simple type, then JSP generation fails. Note that bpws:getVariableData(var, part, query) and bpws:getVariableData(var, query) work even if the queried data is a simple type. You only need to make sure the variable itself is not a simple type. XSI extensions are not supported. No special handling of XSD order indicators occurs (that is, choice , all , and sequence ). For example, the default JSP does not check if you entered both firstname and about wallpaper, lastname : 15.8.3.1.1 Customizing the Autogenerated JSP. The autogenerated default JSP is coursework generic, and so may require changes to school improve its look and feel. The JSP works in acid, conjunction with the mapping file to determine which elements in the payload are displayed in the form. 15.8.3.1.2 Customizing the chiropractic school admissions Mapping File. The mapping file gives you control of the presentation. The mapping file is an XML file that contains a list of viewable fields. Acid. The root element in glass analysis, the mapping file contains its targetNameSpace , other namespaces, and xmlEditable as its attributes. All the elements that are simple types are listed as fields in coursework, the mapping file. Essays Wallpaper. Along with these elements, their immediate parents are listed as well for multilanguage support. Each field has three properties defined in the mapping file. They are xpath , editable , and coursework, resource_key . Nios. The xpath property defines the XPath of this field. It is always prefixed by /ns0:task/ns0:payload . This is the XPath to the root of the payload object. When maxOccurs is greater than 1 , it is denoted by
  • . For example, /ns0:task/ns0:payload/company[*]/ceo shows that maxOccurs is greater than 1 for the company field. Do not modify this XPath field because it is also a unique key that determines the identity of the coursework field. The editable property defines if this field is editable. It defaults to true . If the value of this field is changed to false , the default JSP shows a disabled text field that disallows value changes. The resource_key property is for multilanguage support. To ensure that your autogenerated JSP shows a preferred language other than English, you must supply a resource bundle. Follow these steps to add a resource bundle: Create a bundle file (for example, MyBundle ). Glass Analysis Essay. This file points to a properties file that resides at acid coursework the root of the project.
  • The following code shows an example of MyBundle_en-US.properties : In this case, if a field is defined in your mapping file as follows. in the default JSP returns the string i18n Task if your locale is set to en-US . Similarly, if your locale is set to French, the proper properties file ( MyBundle_fr.properties ) is picked up. Specify the resource bundle name and admissions essay, location in the Resource Details window of the Human Task editor, as shown in Specifying Multilingual Settings. 15.8.3.1.3 Customizing the Default JSP. If the mapping file does not provide enough control, you can modify the default JSP file. Only modify the section after the label: Most JSP modifications can be made in the JSP design view of Oracle JDeveloper. By default, all the fields are set to acid coursework text field. If you want to glass analysis change a text field to acid coursework a text area, you can do the following. Select Text Area in the Component Palette , as shown in Figure 15-34. Figure 15-34 Oracle JDeveloper JSP Design View. Menagerie Analysis Essay. Drop it into the position of the text field you want to replace. Note that the acid coursework name of the text field is set by calling the function oracle.bpel.services.workflow.worklist.payload.PayloadFormGenerator.constructName(String xpath) , and expert thesis, the value of the field is set by PayloadFormGenerator.selectNodeValue(Element payload, String xpath, Map namespace) . These functions must be used to construct form field names and to acid retrieve form field values. Set the essays the yellow text area's name and value to the same name and value as the text field. Delete the text field. In the coursework place you want to insert text or other HTML elements that are not in a table, add text by typing it or add an how do you use citations in a HTML element by dragging and dropping the HTML component from the acid coursework Component Pallet . If the place you want to insert HTML elements is in an HTML table, to insert text or a horizontal rule, first add a table row by clicking a row, right-clicking, and internet citations research, selecting Insert Row . After a row is coursework inserted, you may need to merge all the cells in the row by selecting all the expert thesis cells in the row and right-clicking to select Merge Cells . Then you can either type your text or drag and drop your HTML component. If you want to change the layout of the table or form, highlight the coursework section you want to modify, right-click, and select table or form. If you want to format the text, use the toolbar's color and style buttons. Nios. It is recommended that you modify the default JSP's look and feel only. You should preserve the acid functions being used in the JSP. You must not alter the hidden parameters being submitted in the yellow, the HTML form, because the Update button invokes form submission to the WFTaskUpdate that expects certain values. If your change is acid complicated and has programming logic in essays about wallpaper, it, you must switch to the source view and modify the JSP code directly. By putting the statement %@ page pageEncoding=UTF-8 % in the default JSP, UTF-8 is set as the acid default encoding. The HelpDeskServiceRequest demo in SOA_Oracle_Home bpelsamplesdemos for an example of an autogenerated JSP and how to change the school payload presentation. 15.8.3.1.4 Displaying a Check Box on acid, the Worklist Payload JSP. Follow these instructions if you want to customize the JSP page to display a selectable check box instead of a text box. Note that the input for the status is generated as follows. Substitute the essays the yellow entire code block shown in Step 1 with the acid coursework following code block: Add the following JavaScript . This is required because the value for the check box field in JavaScript is always the value defined in the input element. 15.8.4 Generating a Custom Task Display Form. For this release, task display forms are generated by using templates consisting of different regions. Oracle JDeveloper automatically includes three templates and two default JSPs: The three templates are as follows: Three Region JSP #x2014; Consists of the header, body and expert thesis, footer regions. These regions can be displayed by using custom JSP, XSL, default JSP, or autogenerated JSP files. The automatically generated JSP displays the body region. Two Region JSP #x2014; Consists of the header and footer regions. Acid. One Region JSP #x2014; Consists of the body region. Assignment Answers. The two default JSPs are as follows: The header JSP displays task attributes such as task number, priority, title, and so on. The footer JSP displays task attributes such as attachment, comments, and so on. The custom task display form enables you to select the coursework template and rendering type for displaying task details. Select Custom Task Form from the list shown in Step 2. The Task Form Display window appears. Select a template from the Current Template list. Three are three seeded regions (three region JSP, two region JSP, and one region JSP). After selecting a region, you can specify how to render it. See the following sections for details about generating the different types of chiropractic essay, custom task display forms: This option enables you to automatically generate a form for the payload of the task. Acid Coursework. You can also optionally specify which particular task parameters you want to include in the displayed form. Select Auto JSP from the Body list in nios, the Rendering section. An icon displays to the right of Body.jsp in the Source section. The Payload Mapping window appears. This window enables you to select message attributes. Select message attributes to coursework include in the autogenerated JSP. Click OK to return to the Task Form Display window. This option enables you to invoke an external custom JSP to academic honesty display the task details. You can also specify URL parameters to pass to this JSP at run time. Three parameters are passed in acid coursework, by default #x2014; taskID , version , and workflowContext . Expert Thesis. Additional parameters must be explicitly specified. Select Custom JSP from the Header list in the Rendering section. A second icon displays to acid the right of the Source section for editing custom JSP parameters. Enter the custom JSP file name in the Source field or click the first icon to select the JSP file to use. This JSP is used in the project and deployed with the other JSP files. Click the second icon to specify run time JSP parameters. The Payload Mapping window appears. This window enables you to add input JSP parameters. Add a parameter by nios assignment answers clicking the + sign. Add a name in the Name column. Click the icon to the right of the acid row to display the Expression Builder window to honesty essays dynamically enter a value for the XPath column. For this example, the custom JSP is using a parameter named PRIORITY to receive the task ID from the request. Therefore, PRIORITY is specified as the name and acid coursework, /tns:task/tns:systemAttributes/tns:PRIORITY is specified as the XPath expression. Creating Custom JSP Forms for details about explicitly passing parameters. This option provides the essays about wallpaper default Header1.jsp and Footer1.jsp files to display the header and acid, footer regions, respectively. This option enables you to specify an XSL to convert the task XML document into an HTML document for the form. Note that this is useful only to create read-only forms. Enter the menagerie analysis HTTP location in the Source field or click the first icon to select the input XSL file to use. 15.8.5 Deploying Task Display Forms. Acid Coursework. Workflow task display forms are deployed by chiropractic using the deployTaskForm ant target. This target is executed when you deploy the coursework BPEL process from Oracle JDeveloper or from the command prompt. This target generates an EAR file that includes all generated default or custom JSPs. This generated EAR file is deployed as a child of the academic honesty essays Oracle BPEL Process Manager application. Acid. The following directory structure is generated. The following subdirectories and chiropractic school admissions essay, files are created: A J2EE enterprise archive directory named ear is created. EAR deployment descriptors are generated and acid, stored in answers, the META-INF subdirectory. A Web archive (WAR) directory named war is coursework created. This directory contains the following files and menagerie analysis, subdirectories: Style sheets and Java server page files for the header ( Header1.jsp ), footer ( Footer1.jsp ), and body ( payload-body.jsp and payload-body.xml ) are generated and stored in the war directory. Web service deployment descriptors are generated in acid, the subdirectory WEB-INF . You can delete all form-related files by right-clicking the human task folder in glass menagerie analysis, the Application Navigator and selecting Delete Task Form files . Acid. As described earlier, you can register a custom JSP for expert thesis, rendering the task details in acid coursework, the worklist. The BPEL worklist invokes any custom JSP that has been registered. Follow these instructions to essays create a custom JSP form. Get the coursework task ID, version, and context ID from the request. School Admissions Essay. Get the workflow context object based on the context ID. Get the task object based on coursework, the task ID and version. Use the task query service API getTaskDetailsById if the version is null or empty. Otherwise, use the getTaskVersionDetails API. Use the task object methods to get the values you want to display in the JSP. In the nios assignment answers case of update support, generate the hidden HTML type for the following parameters, so that the update servlet can read these parameter values: You can get the values for acid coursework, these parameters in the custom JSP servlet request object. Essay. Run time invokes the custom JSP by passing these parameters. The following custom JSP code shows how to use these steps to acid write a custom JSP that uses the local query service and verification APIs. For this reason, deploy this JSP as a child of the hw_services application. Essay. If you do not want to acid deploy to the same application server, replace local APIs with remote APIs. 15.8.6.1 Adding Update Support in the Custom JSP. You Use Internet In A Research Paper. To add update support in the custom JSP, you can write the servlet that uses the remote task service APIs to update the custom JSP task values: Get the task object by using the same steps as used in the custom JSP. Query the task object and set the values based on the custom JSP form. For example, if the custom JSP form allows a user to update the priority attribute, then get the priority JSP form value and call task.setPriority( newvalue ); . Use the remote task service API to update the task. Get the acid coursework value from essay, servlet parameter WORKLIST_NEXT_PAGE_PARAMETER_NAME , which the custom JSP page includes as a hidden parameter. Redirect the page to the URL. 15.9 How Changes to a Workflow Appear in acid coursework, Worklist Application. Changes made in Oracle BPEL Control to a BPEL process that includes a human task impact how tasks display in about wallpaper, Oracle BPEL Worklist Application: If you abort an active BPEL process instance on the Instances tab, associated tasks are marked as Stale in the Status column of the Oracle BPEL Worklist Application home page. If you delete a BPEL process instance on the Instances tab, all associated tasks are deleted. If you undeploy a BPEL process on the BPEL Process tab, associated tasks are marked as Stale in acid coursework, the Status column of the Oracle BPEL Worklist Application home page. 15.10 Notifications from Workflow Services. Notifications are sent to academic honesty alert users of coursework, changes to the state of a task. Notifications can be sent through any of the school admissions essay following channels: e-mail, telephone voice message, fax, pager, or SMS. Acid. This section contains the chiropractic following topics: 15.10.1 Configuring the Notification Channel. After configuring the notification service for e-mail and other channels in Oracle JDeveloper, set the NotificationMode parameter for the notification service to either ALL or EMAIL in the SOA_Oracle_Home bpelsystemservicesconfigns_emails.xml file. By default, this value is set to NONE , meaning that no notifications are sent. The possible values for the NotificationMode attribute are: ALL #x2013; the acid coursework e-mail, SMS, voice, fax, and pager channels are configured and notification is sent through any channel. EMAIL #x2013; Only the e-mail channel is configured for how do you use citations in a paper, sending notification messages. NONE #x2013; No channel is coursework configured for sending notification messages. This is the default setting. The notifications for a task can be configured during the creation of essays, a task in the Human Task editor. Acid Coursework. Notifications can be sent to different types of participants for different actions. The actions for academic essays, which a task notification can be sent are as follows: Assigned #x2014; when the task is assigned to users or a group. This action captures the following task actions #x2014; acquire, adhoc route, delegate, escalate, information for a task is submitted, push back, reassign, release, and resume. Acid Coursework. Task is completed. Expert Thesis. Task is errored. Task is expired. Information is requested for coursework, a task. You Use Internet In A Paper. Task outcome is updated. Task is suspended. Task is acid coursework withdrawn. Notifications can be sent to users involved in the task in glass menagerie analysis, various capacities. This includes: Assignees #x2013; the acid coursework users or groups to whom the task is currently assigned. Initiator - the user who created the task. Creator #x2013; the user who created the task. Approvers #x2013; the essay users who have approved the task so far. This applies to a sequential list of approvers participant type where multiple users have approved the task and a notification must be sent to all. Owner #x2013; the owner of the acid task. When the task is how do you use in a research paper assigned to a group, each user in the group is sent a notification if no notification endpoint is available for the group. Coursework. Service Configuration chapter of the Oracle BPEL Process Manager Administrator's Guide for details about editing the ns_emails.xml file and (for the JAZN XML provider) users-properties.xml file. Each e-mail notification can contain the following parts: The notification message. The HTML content from the nios assignment answers worklist application #x2014; This is a read-only view of the worklist application on the task. Task attachments #x2014; If the notification includes task attachments. Coursework. Notifications through SMS, voice, fax, and pager contain only the chiropractic admissions essay notification message. The notification message is an XPath expression that can contain static text and dynamic values. In creating the messages, only the task BPEL variable is available for dynamic values. This restriction is coursework because the messages are evaluated outside the context of the BPEL process. The payload in chiropractic school, the task variable is also strongly typed to contain the type of the acid payload for XPath tree browsing. The XPath extension function hwf:getNotificationProperty(propertyName) is available to get properties for a particular notification. The function evaluates to corresponding values for each notification. The propertyName can one of the following values: recipient #x2014; The recipient of the notification. Answers. recipientDisplay #x2014; The display name of the recipient. taskAssignees #x2014; The task assignees. taskAssigneesDisplay #x2014; The display names of the task assignees. Acid. locale #x2014; The locale of the recipient. taskId #x2014; The ID of the task for which the notification is meant. taskNumber #x2014; The number of the task for which the the yellow notification is meant. appLink #x2014; The HTML link to the worklist application task details page. The following example demonstrates the use of hwf:getNotificationProperty and hwf:getTaskResourceBundle together: This results in a message similar to the following: 15.10.3 Configuring Messages in Different Languages. It is acid coursework possible to get internationalized messages in the notification content using one of the following methods. If you want to use values from the resource bundle specified during the task definition, use the how do citations paper XPath extension function hwf:getTaskResourceBundleString(taskId, key, locale?) . This function returns the internationalized string from the resource bundle specified in the task definition. The locale of the notification recipient can be retrieved with the function hwf:getNotificationProperty('locale') . The task ID corresponding to a notification can be retrieved with the function hwf:getNotificationProperty('taskId') . If a different resource bundle is used, the XPath extension function orcl:get-localized-string() can be used to retrieve localized messages. Task actions can be performed through e-mail if the task is set up to enable actionable e-mail (the same actions can also be performed from the Oracle BPEL Worklist Application). An actionable e-mail account is the account in which task action-related e-mails are received and processed. This e-mail account name is coursework identified by about the yellow wallpaper the element actionableEmailAccountName in the configuration file SOA_Oracle_Home bpelsystemservicesconfigwf_config.xml . Ensure that you select Make e-mail messages actionable in the Notification Settings section of the Human Task editor to make e-mail notifications actionable. (See Figure 15-25.) This enables you to acid coursework perform task actions through e-mail. If a notification is actionable, the glass analysis essay e-mail contains links for each of the custom outcomes. Clicking on the links invokes the compose window of the acid coursework e-mail client. You do not have to change anything in the subject or the body in this e-mail. If you change the content with the glass menagerie NID substrings, the e-mail is not processed. Acid. Figure 15-35 shows an actionable e-mail sample: Figure 15-35 Actionable E-mails. 15.10.5 Sending Inbound and Outbound Attachments. If the include attachments flag is checked; only e-mail is menagerie analysis sent. The e-mails include all the task attachments as e-mail attachments. Select Send task attachments with e-mail notifications in the Notification Settings section of the Human Task editor. Coursework. (See Figure 15-25.) In the actionable e-mail reply, the user can add attachments in the e-mail and these attachments are added as task attachments. In the actionable e-mail reply, the user can add comments in assignment answers, the e-mail between Comments[[' and coursework, ']] and those contents are added as task comments. Essays. For example, Comments[[looks good]]. In previous releases, the workflow outbound notification was not reliable. This meant that notifications were sent by using threads and the list of notifications to send was stored in memory. If Oracle BPEL Server went down, workflow lost any notification messages that had not yet been sent. With release 10.1.3, the acid workflow outbound notification service uses queues with the persistency service to send notifications to users. Whenever a workflow needs to send a notification to a user, it stores the paper task information such as notification ID, task ID, version, and so on in the dehydration store and enqueues the acid coursework notification ID to the queue. A message-driven bean (MDB) listening on this queue dequeues the message and creates the notification message to send to the user. It then uses the notification service to send this message, which uses the queue with the dehydration store. 15.10.8 Sending Secure Notifications. If a notification is marked as secure in the Notification Settings section of the admissions essay Human Task editor, a default notification message is acid coursework used. (See Figure 15-25.) The default notification message includes a link to the task in the Oracle BPEL Worklist Application. You must log in to see task details. 15.10.9 Channels Used for chiropractic essay, Notifications. Coursework. The channel through which a user is notified is expert thesis determined by the notification preference attribute of the user specified in JAZN. Coursework. The notification preference is identified by the attribute orclWorkflowNotificationPreference . In a JAZN file-based system, the value for this attribute can be changed in the users-properties.xml file located at SOA_Oracle_Home bpelsystemservicesconfig . In an Oracle Internet Directory-based system, the user properties can be changed using the internet citations in a Oracle Delegated Administration Service. If this attribute is not set, the e-mail channel is used as the default. Tasks can be configured to send reminders, which can be based on the time the task was assigned to a user or the acid coursework expiration time of a task. Academic. The number of reminders and the interval between the coursework reminders can also be configured. The message used for reminders is the academic honesty essays message that is meant for acid coursework, ASSIGNEES when the task is marked as ASSIGNED . You set reminders in the Notification Settings section of the Human Task editor. (See Figure 15-25.) Reminder configuration involves these parameters. Recurrence #x2014; The recurrence specifies the essays about the yellow number of times reminders are sent. The possible values for recurrence are EVERY , NEVER , 0 , 1 , 2 #x2026;, 10 . RelativeDate #x2014; The relativeDate specifies if the reminder duration is computed relative to the assigned date or to acid coursework the expiration date of the task. The possible values for the relativeDate are ASSIGNED and EXPIRATION . Duration #x2014; The duration from the relativeDate and the first reminder and each reminder since then. The data type of duration is xsd:duration , whose format is defined by ISO 8601 under the form PnYnMnDTnHnMnS . The capital letters are delimiters and internet in a research paper, can be omitted when the corresponding member is not used. Examples include PT1004199059S , PT130S , PT2M10S , P1DT2S , -P1Y, or P1Y2M3DT5H20M30.123S . The following examples illustrate when reminders are sent. Acid Coursework. The relativeDate is expert thesis ASSIGNED , the recurrence is EVERY , and acid, the reminder duration is PT1D . If the essays about the yellow task is assigned at 3/24/2005 10:00 AM , then reminders are sent at acid 3/25/2005 10:00 AM , 3/26/2005 10:00 AM , 3/27/2005 10:00 AM , and so on until the user acts on the yellow wallpaper, the task. If the relativeDate is EXPIRATION , the recurrence is acid coursework 2 , the reminder duration is school admissions PT1D, and the task expires at 3/26/2005 10:00 AM , then reminders are sent at 3/24/2005 10:00 AM and 3/25/2005 10:00 AM if the task was assigned before 3 /24/2005 10:00 AM . Acid. If the relativeDate is essays the yellow wallpaper EXPIRATION , the recurrence is coursework 2 , the reminder duration is PT1D , the task expires at 3/26/2005 10:00 AM , and essays, the task was assigned at acid 3/24/2005 3:00 PM , then only one reminder is sent at 3/25/2005 10:00 AM . Table 15-14 shows the internet citations in a end-to-end workflow examples included with Oracle BPEL Process Manager. Acid. Follow the documentation included in the same directories with these samples. In addition to the demonstration features listed in Table 15-14, all samples show the use of worklist applications and workflow notifications. Table 15-14 End-to-End Examples. Integration with a business rule engine. Adding attachments to tasks. Use of decision service to how do you use in a determine the levels of approvals required for a particular expense request.

Group assignment (in StarLoan process) Custom worklist user interface (in LoanFlowPlusUI and StarLoanUI) FYI tasks (in LoanFlowPlus process) This example describes how to create a vacation request business process. In this business process, the how do you use citations in a research manager of a user requesting a vacation approves or rejects the request. The approval or rejection is a one-step process. This example highlights the use of the following: Modeling a single approval workflow using Oracle JDeveloper. Using the Oracle BPEL Worklist Application to view and acid, respond to tasks. This example assumes the following: You are familiar with basic BPEL constructs, including BPEL activities and partner links, and basic XPath functions. Familiarity with Oracle JDeveloper#x2014;the environment for creating and deploying BPEL processes#x2014;is also assumed. You must configure the e-mail server settings for chiropractic essay, the account Default to acid enable e-mail notifications. The Default account is used to send e-mails. The e-mail server configuration is in. The following code example from the file shows the parameters that may require configuration in bold. You must set the NotificationMode parameter to one of the following values in the ns_emails.xml file: ALL #x2013; If you have the e-mail, SMS, voice, fax, and pager channels set up. EMAIL #x2013; If you have only the e-mail channel set up. You must change the e-mail address for the user jstein to an accessible e-mail address. If the XML-based JAZN provider is chiropractic admissions essay used, these properties can be changed in: The following XML segment from the users-properties.xml file shows where the e-mail is configured: You must restart Oracle BPEL Process Manager after making any of the preceding changes. 15.11.3 Modeling the Vacation Request Process. In this phase of the tutorial, you create a new project, OrderApproval, and define the human workflow process, a single approver workflow in acid coursework, which the order is approved or rejected.

Table 15-15 lists the type of SOAP, EJB, and Java support provided for the task services. Table 15-15 EJB, SOAP, and Java Support. Table 15-16 lists the location for the SOAP WSDL file for each task service. Table 15-16 SOAP WSDL Location for the Task Services. 15.12.2 Security Model for Services. With the exception of the identity service, all services that use the above-mentioned APIs (SOAP, remote EJB, local EJB, and Java WSIF) require authentication to be invoked. Chiropractic Admissions. All the acid coursework above channels support passing the user identity using the workflow context. The workflow context contains either of the following: Login and password. The task query service exposes the authenticate operation that takes the login and password and returns the workflow context used for glass menagerie essay, all services. Optionally, with each request, you can pass the acid coursework workflow context with the login and password. The authenticate operation also supports the concept of creating the context on behalf of a user with the admin ID and admin password. This enables you to expert thesis create the acid context for admissions, a logged-in user to the Oracle BPEL Worklist Application if the password for that user is coursework not available. 15.12.2.1 Security in SOAP Web Services. SOAP Web services also support Web service security. When Web service security is how do you use internet research used, the coursework workflow context does not need to be present in the SOAP input. Nios Assignment. The Web service security can be configured from the Oracle Enterprise Manager 10 g Application Server Control Console. Workflow service SOAP clients cannot be used when Web service security is used. Configuring Single Sign-on Using SAML in the Oracle Application Server Web Services Security Guide for acid, details about propagating the identity of a user from a Web application to honesty essays the Web service. Acid. The workflow service EJBs also take a workflow context parameter that is used for authentication and authorization. 15.12.2.3 Creating Workflow Context on expert thesis, Behalf of a User. The authenticate API operation on the task query service can create the workflow context on behalf of acid, a user by passing the user ID and password of an academic admin user in the request. An admin user is acid a user who has the BPMWorkflowAdmin role. This created context is as if it was created using the password on behalf of the user. In this example, the workflow context is created for user jcooper . The task service exposes operations to act on tasks. Table 15-17 describes the operations of the task service. Package oracle.bpel.services.workflow.task corresponds to the task service. Table 15-17 Task Service Methods. The task query service queries tasks based on a variety of search criterion such as keyword, category, status, business process, attribute values, history information of chiropractic admissions, a task, and so on. Table 15-18 describes the acid coursework operations of the task query service, including how to use the service over SOAP. Package oracle.bpel.services.workflow.query corresponds to the task query service. Table 15-18 Task Query Service Methods. assignmentFilter #x2014; Filters tasks according to whom the menagerie analysis essay task is assigned, or who created the task. Possible values for the assignment filter are as follows: ADMIN #x2014; No filtering; returns all tasks regardless of assignment or creator. ALL #x2014; No filtering; returns all tasks regardless of assignment or creator. Acid Coursework. CREATOR #x2014; Returns tasks where the context user is the creator. GROUP #x2014; Returns tasks that are assigned to one of the groups of which the context user is a member. MY #x2014; Returns tasks that are assigned to the context user. Assignment Answers.

This only returns tasks where the string is contained in the task title, task identification key, or one of the task text flex fields. predicate #x2014; An optional oracle.bpel.services.workflow.repos.Predicate object that allows clients to chiropractic school specify complex, SQL-like query predicates. Acid Coursework. Note: To use the task query service over SOAP, call Predicate.enableXMLSerialization(true); to make the predicate object serializable. This section describes the identity service component of Oracle BPEL Process Manager. The identity service is a thin Web service layer on top of the Oracle Application Server 10 g security infrastructure, namely OracleAS JAAS Provider (JAZN), or any custom user repository. It enables authentication and authorization of users and the lookup of user properties, roles, group memberships, and privileges. Some users and roles are automatically created when Oracle BPEL Process Manager is installed. Seeded users include: The identity service predefines the following roles, which can be granted to users to perform workflow-related operations: PUBLIC #x2014;This role is an implicit JAZN role; it does not need to be granted explicitly to any of the users. If any user can authenticate with the worklist, then they can see tasks assigned to them or groups they belong to expert thesis and act on these tasks. Acid Coursework. The BPMPublic role can be used and explicitly granted to glass menagerie each user if a third-party provider does not support an implicit PUBLIC role. BPMWorkflowReassign #x2014;This role enables a user to reassign tasks to any other user in the organization. Acid. A manager can always delegate tasks to any users under him in the organization hierarchy without any Reassign privileges. However, to reassign to users outside the management hierarchy, the BPMWorkflowReassign role is essays about required. BPMWorkflowSuspend #x2014;This role enables users to suspend a process. If a process is suspended, then the acid coursework expiration time does not apply. When the nios assignment answers process is acid coursework resumed, the expert thesis expiration date is recomputed. Users cannot suspend the acid workflow if the process designer has designated Suspend as a restricted action, even if the user has the BPMWorkflowSuspend role. BPMWorkflowViewHistory #x2014;In general, a user can see only the task assignment sequence as part of their worklist. This role enables a user to drill down further into the BPEL business process audit trail from the task approval sequence. BPMWorkflowAdmin #x2014;This role enables a user to perform system actions on any workflow in the system. Answers. This role does not allow you to change the outcome of the task (such as approve or reject); it only acid coursework, allows you to perform actions such as delegate, escalate, and assignment, suspend. Only the task assignee or the task owner can change the outcome of the task. BPMSystemAdmin #x2014;Both BPMWorkflowAdmin and BPMSystemAdmin have the same level of acid, workflow privileges. BPMDefaultDomainAdmin #x2014;This role provides a user with access to the default domain through Oracle BPEL Control. Oracle BPEL Process Manager Administrator's Guide for instructions on configuring the expert thesis identity service and additional details about the BPMSystemAdmin and acid coursework, BPMDefaultDomainAdmin roles. Some of these roles are nested. The BPMWorkflowReassign , BPMWorkflowSuspend , and BPMWorkflowViewHistory roles are granted to the BPMWorkflowAdmin role. The BPMSystemAdmin role is granted to the seeded bpeladmin user. The following table represents the relationship between the grantees and roles: You use directory-specific tools to create realms, users, or groups. For example: To create users and academic honesty, groups when using OID, you use the Oracle Delegated Administration Services tools. Acid Coursework. See Oracle Identity Management Guide to Delegated Administration for more information. To create user and group credentials when using the XML-based JAZN provider, you use the JAZN Admintool to modify the jazn-data.xml file. To add or remove an XML-based JAZN user or role, the JAZN Admintool must be used. You can manually edit the users-properties.xml file to specify detailed user properties that JAZN does not support. For example, to add a user to a specified realm, issue the following command: java -jar jazn.jar -user adminUser -password adminPassword -adduser realmName newUser newUserPassword. The JAZN Admintool provides different command options. You can list all the options and their syntax with the -help option, as in: java -jar jazn.jar -help. If you are using a third-party LDAP server or a custom user repository, you must use the chiropractic admissions specific tools available for that directory. 15.12.5.2 Identity Service Providers. Coursework. Oracle BPEL Process Manager identity service supports three types of providers: JAZN, third-party LDAP, or custom plug-in, as shown in Figure 15-36. Essay. Figure 15-36 Identity Service Providers. The identity service providers perform the following operations: Authentication#x2014;authenticates users given their username and password. Authorization#x2014;determines roles and group memberships for a specific user. These roles are then used to control access to various work items and operations on the worklist. Retrieve user properties#x2014;includes contact information such as first name, last name, phone, e-mail, preferred notification channel, language preference, time zone, and organization details such as manager name and reportees. The JAZN provider mode, which is preconfigured, delegates all authentication and acid coursework, authorization inquires to the JAZN layer. Two JAAS providers are supplied as part of the OC4J security infrastructure: the XML-based file and LDAP-based OID. XML-Based JAZN Provider Type #x2014; The XML-based provider type is used for about wallpaper, lightweight storage of acid, information in the XML files. All the the yellow user names, roles, and permissions are stored in XML files. Acid Coursework. In this case, user names, passwords, and privileges are stored in the jazn-data.xml file. In addition, Oracle BPEL Process Manager uses a user-properties.xml file that works in conjunction with this file to store detailed user properties such as name, e-mail, phone, and manager. Glass Menagerie Essay. LDAP-Based JAZN Provider Type (Oracle Internet Directory) #x2014; The LDAP-based provider type is based on the Lightweight Directory Access Protocol (LDAP) for centralized storage of information in a directory. OID is a standard LDAP-based directory that provides a single, centralized repository for all user data. It allows sites to manage user identities, roles, authorization, and authentication credentials, as well as application-specific preferences and profiles in a single repository. The third-party LDAP provider mode enables identity service to work with third-party LDAP servers such as Sun Directory Server (iPlanet), Microsoft Active Directory, or openLDAP. In this mode, identity service assumes that the directory is the central repository of all user data, including authentication credentials, roles, and profiles. The standard organizationalPerson , inetOrgPerson objects from the LDAP schema retrieve these details. 15.12.5.2.3 Custom User Repository Plug-ins. This mode enables you to plug in a non-LDAP-based user repository by registering a custom identity service provider. The custom identity service plug-in must implement the BPMIdentityService interface (see Javadoc). This identityservice class name must be registered in is_config.xml . See SOA_Oracle_Home bpeldocsworkfloworacletippcservicesidentity for Javadoc on the BPMIdentityService interface. The identity service supports the following user properties : Given name, middle name, and last name. Home phone number. Acid. Mobile phone number. Owners (applies to groups and roles, but not users) Language preference (Java locale) Notification preference (preferred notification channel) The preceding properties are optional for chiropractic essay, Oracle BPEL Process Manager users. However, some features, such as task notification, are not available if the contact information is not present in acid coursework, the directory or in the users-properties file for the JAZN XML-based provider. Also, automatic escalation and manager views are not available if the manager field is not available to the identity service. If the user is not listed among the owners of the group, they cannot modify the rule defined for the group. The service configuration chapter of Oracle BPEL Process Manager Administrator's Guide for instructions on defining group ownership. The following OID objectClasses specify user and role properties such as mail , manager , and essay, telephoneNumber . The identity service maintains a connection pool to retrieve these properties from the coursework LDAP directory. Glass Analysis. If you are using the XML-based JAZN provider, the same entries are represented as XML elements in the users-properties.xml file in. The identity service enables you to specify multiple configuration settings (to express identity contexts, supported realms, and so on) in the is_config.xml file. The business process uses one of the defined configurations at run time. The configuration must specify the realm name to enable a business process to coursework resolve the context at run time. For the JAZN provider, the realm name must match one of expert thesis, supported JAZN realm names. Otherwise, a run time exception is thrown. For the JAZN XML-based provider, extended user and role properties for different realms must be stored in different files. For the acid LDAP provider, the realm name can be any unique name, while the context is defined by the LDAP URL, user search base, and role search base nodes in the LDAP server tree. Menagerie Analysis. These properties are controlled by the connection , userControls , and roleControls provider elements in is_config.xml . If the is_config.xml file contains more than one configuration, then one is defined as the default configuration. The default context is acid coursework used by the BPEL process if no specific context information is found at expert thesis run time. The identity service resolves the configuration context based on the realm name. Coursework. The service configuration chapter of the Oracle BPEL Process Manager Administrator's Guide for configuration instructions. 15.12.5.5 Authentication, Authorization, and Identity Service Providers. The identity service supports authentication, authorization, and identity service providers. Citations In A Paper. The identity service provider is the default pseudoservice provider. It must be defined for each configuration in the is_config.xml file. It delegates all calls either to the authentication or authorization service provider. By default, all three service providers share the same context setting defined in the identity provider.The identity service can define additional service providers with its own setting attributes for coursework, authentication or authorization services.If the provider service attribute is set to expert thesis Authentication , the setting and the provider context are used only for all authentication calls for the configuration. Acid Coursework. If the provider service attribute is set to Authorization , the setting and academic, provider context are used only for authorization calls. The multiple service providers section of the service configuration chapter of the Oracle BPEL Process Manager Administrator's Guide for an example of coursework, a configuration with two providers: The JAZN XML-based identity service provider is used for all calls, except authentication. The custom plug-in provider is used only for authentication calls. The notification service exposes operations that can be invoked from the BPEL business process to send notifications through e-mail, voice, fax, pager, or short message service (SMS) channels. Oracle BPEL Process Manager Administrator's Guide for instructions on configuring notification service delivery channels. Menagerie. Task metadata service exposes operations to retrieve metadata information related to a task. Table 15-19 describes these methods. Package oracle.bpel.services.workflow.metadata corresponds to the task metadata service. Table 15-19 Task Metadata Service Methods. The user metadata service provides methods for managing metadata specific to individual users and groups. It is used for acid, getting and setting user worklist preferences, managing user custom views, and managing workflow rules for users and groups. For most methods in the user metadata service, the authenticated user can query and update their own user metadata. However, they cannot update metadata belonging to other users. In the case of expert thesis, group metadata (for example, workflow rules for groups), only a user designated as an owner of a group (or a BPMWorkflowAdmin user) can query and update the metadata for that group. Coursework. However, a user that has been granted the BPMWorkflowAdmin role can query and update metadata for any user or group. Table 15-20 describes the methods in the user metadata service. Package oracle.bpel.services.workflow.user corresponds to the user metadata service. Table 15-20 User Metadata Service Methods. Chapter 16, Worklist Application for details about the rule configuration and user preference pages. Chiropractic School. The runtime config service provides methods for managing metadata used in the task service run time environment. It principally supports management of acid coursework, task payload flex field mappings. The task object used by school essay the task service contains a number of flex field attributes, which can be populated with information from the task payload. This allows the task payload information to be queried, displayed in task listings, and used in workflow rules. The runtime config service allows administrators to create mappings between simple task payload attributes and these flex field attributes. Only a user with the coursework BPMWorkflowAdmin privilege can make updates to payload mappings. However, any authenticated user can use the expert thesis query methods in this service. An administrator can create attribute labels for acid, the various flex field attributes. These attribute labels provide a meaningful label for the attribute (for example, a label Location may be created for the flex field attribute TextAttribute1 ). A given flex field attribute may have multiple labels associated with it. This attribute label is what is about the yellow displayed to users when displaying lists of attributes for a specific task in the worklist application. The attribute labels for a specific task type can be determined by calling the getTaskAttributesForTaskDefinition method on the task metadata service. When defining attribute labels, the following fields are automatically populated by the service. You do not need to specify values for these attributes when creating or updating attribute labels: Valid values for the task attribute field are as follows: TextAttribute1 through TextAttribute10. FormAttribute1 through FormAttribute5. UrlAttribute1 through UrlAttribute5. DateAttribute1 through DateAttribute5. NumberAttribute1 through NumberAttribute5. Mappings can then be created between task payload fields and the attribute labels. For example, the payload field customerLocation can be mapped to the attribute label Location . Acid Coursework. Different task types can share the same attribute label. This allows payload attributes from different task types that have the same semantic meaning to be mapped to the same attribute label. Only payload fields that are simple XML types can be mapped. The runtime config service also provides methods for querying the dynamic assignment functions supported by the server. Table 15-21 describes the methods in the runtime config service. Package oracle.bpel.services.workflow.runtimeconfig corresponds to the runtime config service. Nios Assignment. Table 15-21 Runtime Config Service. 15.12.9.1 Internationalization of Attribute Labels. Attribute labels provide a method of attaching a meaningful label to a task flex field attribute. It can be desirable to present attribute labels that are translated into the appropriate language for the locale of the user. To achieve this, you can add entries to the WorkflowLabels.properties resource property file, and coursework, associated resource bundles in school admissions, other languages. This file exists in the SOA_Oracle_Home bpelsystemservicesconfigwfresource directory. Entries for flex field attribute labels must be of the form: For instance, the entry for coursework, a label named Location is: Note that adding entries to these files for internet citations in a, attribute labels is optional. If no entry is present in the file, the name of the attribute label as specified using the API is used instead. 15.13 Configuring the Assignment Service. This section describes how to configure the assignment service. Acid. This section contains the following topics: 15.13.1 Dynamic Assignment Functions. Dynamic assignment functions select a particular user or group from either a group, or from a list of users or groups. The selection is made according to criteria specific to the particular dynamic assignment function. The three dynamic assignment functions shown in answers, Table 15-22 are included with Oracle BPEL Process Manager: Table 15-22 Dynamic Assignment Functions. These functions all check a user's vacation status. A user that is currently unavailable is not automatically assigned tasks. These dynamic assignment functions can be called using the coursework custom XPath functions in a BPEL process or task definition. These XPath functions must be called with at least two, and optionally more parameters: The name of the dynamic assignment function being called. The name of the group on which to execute the function (or a list of users or groups).(Optional) the identity realm to which the user or group belongs (default value is the default identity realm). Menagerie Analysis Essay. Additional optional parameters specific to acid coursework the dynamic assignment function. In the school case of the most-productive assignment function, this is the length of time (in days) to calculate a user's productivity. Acid Coursework. The two other functions do not use additional parameters. In addition, workflow rules created for a group can use dynamic assignment functions to select a member of that group for reassignment of internet in a research paper, a task. In addition to coursework the three functions, a dynamic assignment framework is provided that allows you to implement and configure your own dynamic assignment functions. 15.13.1.1 Implementing a Dynamic Assignment Function. To implement your own dynamic assignment function, write a Java class that implements one or both of the following interfaces: If your dynamic assignment function selects users, implement the first interface. If it selects groups, implement the second interface. If it allows the selection of both users and groups, implement both interfaces. The two interfaces above both extend the interface oracle.bpel.services.workflow.assignment.dynamic.IDynamicAssignmentFunction . Honesty Essays. Your Java class should also implement the acid methods in that interface. These interfaces as shown below: The dynamic assignment framework also provides the utility class oracle.bpel.services.workflow.assignment.dynamic.DynamicAssignmentUtils . This class provides a number of methods that are useful when implementing dynamic assignment functions. 15.13.1.2 Configuring Dynamic Assignment Functions. Dynamic assignment functions are configured using the wf-dynamic-assign-cfg.xml file in the SOA_Oracle_Home bpelsystemservicesconfig directory. Essays The Yellow Wallpaper. Each dynamic assignment function must have an entry in coursework, this file, in the form of a function tag. The function tag must contain two attributes: name #x2014; the name of the function. classpath #x2014; the classpath of the glass analysis class that implements the function. In addition, the function tag can optionally contain any number of property tags. These tags pass initialization parameters to the dynamic assignment function. Each property tag must contain a name attribute. The value of the acid property is specified in the body of the tag. The property values specified in these tags are passed as a map (indexed by nios the value of the name attributes) to acid coursework the setInitParameters method of the dynamic assignment functions. Academic Honesty. Two of the functions have initialization parameters. These are: ROUND_ROBIN #x2014; The parameter MAX_MAP_SIZE specifies the maximum number of sets of users or groups for which the function can maintain ROUND_ROBIN counts. The dynamic assignment function holds a list of users and groups in memory for each group (or list of users and groups) on which it is asked to execute the ROUND_ROBIN function. most-productive #x2014; The parameter DEAFULT_TIME_PERIOD specified the length of coursework, time (in days) over which to calculate the user's productivity. This value can be overridden when calling the most-productive dynamic assignment function. Use an XPath function by specifying an alternative value as the third parameter in the XPath function call. 15.13.1.3 Configuring Display Names for Dynamic Assignment Functions. The runtime config service provides methods for academic honesty, returning a list of available user and acid coursework, group dynamic assignment functions. These functions return both the name of the function, and a user-displayable label for the function. How Do Internet In A. The functions support localization of the display name, so that it displays in the appropriate language for the context user. These functions are used by the worklist application to show a list of available dynamic assignment functions. To specify display names (and appropriate translations) for your dynamic assignment functions, add entries to the resource property file WorkflowLabels.properties , and associated resource property files in other languages. Acid Coursework. This file exists in the SOA_Oracle_Home bpelsystemservicesconfigwfresource directory. Entries for dynamic assignment functions must be of the form: For instance, the entry for the ROUND_ROBIN function is: Note that adding entries to how do internet research these files for dynamic assignment functions is optional. If no entry is present in the file, then the acid coursework name of the chiropractic admissions function (for example, ROUND_ROBIN ') is used instead. 15.13.2 Dynamically Assigning Task Participants with the Assignment Service. Workflow task participants are specified declaratively in a routing slip. The routing slip guides the workflow by specifying the participants and how they participate in the workflow task (for example, management chain hierarchy, sequential list of approvers, and acid coursework, so on). How Do You Use Research Paper. There are scenarios where the workflow task participants are computed dynamically using complex rules. To support such dynamic assignment, an assignment service is used. The assignment service is responsible for coursework, determining the task assignees. You can also implement your own assignment service and plug in that implementation for about wallpaper, use with a particular workflow. This section contains the following topics: 15.13.2.1 Assignment Service Overview. The assignment service determines the following task assignment details in a workflow: The assignment when the task is initiated. The assignment when the task is reinitiated. The assignment when a user updates the task outcome. When the task outcome is updated, the task can either be routed to coursework other users or completed. The assignees from whom information for glass analysis essay, the task can be requested. If the task supports reapproval from the Oracle BPEL Worklist Application, a user can request information for reapproval. The users who reapprove the task if reapproval is supported. The workflow service identifies and coursework, invokes the nios answers assignment service for a particular task to determine the task assignment. For example, a simple assignment service iteration is as follows: A client initiates an coursework expense approval task whose routing is determined by menagerie the assignment service. The assignment service determines that the task assignee is jcooper . When jcooper approves the task, the assignment service assigns the acid coursework task to jstein . The assignment service also specifies that a notification must be sent to wallpaper the creator of the task, jlondon . jstein approves the task and the assignment service indicates that there are no more users to which to assign the task. 15.13.2.2 Implementing an Assignment Service. The assignment service is implemented with the IAssignmentService interface. The workflow service passes the following information to the assignment service to determine the task assignment: Task document #x2014; The task document that is executed by acid the workflow. School Essay. The task document contains the payload and other task information like current state, and so on. Map of properties #x2014; When an acid coursework assignment service is specified, a list of properties can also be specified to correlate callbacks with backend services that determine the task assignees. Academic Honesty Essays. Task history #x2014; The task history is a list of chronologically ordered task documents to coursework trace the history of the task. The task documents in this list contain a subset of how do you use citations in a research paper, attributes in the actual task (such as state , updatedBy , outcome , updatedDate , and so on). 15.13.2.3 Example of Assignment Service Implementation. The assignment service class cannot be stateful because every time workflow services need to call the assignment service, it creates a new instance. The getAssigneesToRequestForInformation method can be called multiple times because one of the acid criteria to show the request-for-information action is that there are users to request information. Therefore, this method is called every time the workflow service tries to determine the essay permitted actions for a task. Acid Coursework. You can implement your own assignment service plug-in that the workflow service invokes during workflow execution. The following example provides a sample IAssignmentService implementation named TestAssignmentService.java . 15.13.2.4 Deploying a Custom Assignment Service. You must use one of the following methods to make an nios assignment answers assignment service implementation class and its related classes available in the class path of Oracle BPEL Process Manager: Load your classes in the SOA_Oracle_Home bpelsystemclasses directory and unzip your JAR files in coursework, the same directory. Change the Oracle BPEL Process Manager shared library to glass essay include your JAR files. You cannot create different versions of the assignment service for use in different BPEL processes unless you change package names or class names. Java classes and JAR files in coursework, the suitcase are not available in the class path and therefore cannot be used as a deployment model for the assignment service. The steps must be repeated for each node in a cluster. The custom escalation function enables you to integrate a custom rule in you use citations in a paper, a workflow. You create a custom task escalation function and register this with the workflow service that uses that function in task definitions. The Advanced Settings section of the Human Task editor enables you to integrate the rule in coursework, a human task. 15.14 Workflow Service and Identity Service Related XPath Extension Functions. Oracle BPEL Process Manager provides XPath extension functions for use with the glass menagerie analysis workflow services and acid, the identity service. XPath extension functions mimic XPath 2.0 standards. Table 15-23 lists the essays about supported workflow service functions and acid, Table 15-24 lists the supported identity service functions. Expert Thesis. Table 15-23 Workflow Service Functions. Table 15-24 Identity Service Functions. 15.14.1 Deprecated Workflow Service and Identity Service Functions. Table 15-25 lists the workflow and identity service functions that are deprecated for this release. Table 15-25 Deprecated Workflow Service and Identity Service Functions. You can specify resource bundles for displaying task details in different languages in Oracle BPEL Worklist Application. In addition, the resource property file WorkflowLabels.properties can be used for setting display names for the following: Dynamic assignment functions. Payload mapping attribute labels. This chapter describes how you can integrate systems and services with human workflow into a single end-to-end process flow using Oracle BPEL Process Manager. The predefined workflow participant types are described, as are the components of workflow services#x2014;the task service, task routing service, identity service, worklist service, notification service, and others.
