Retrieving Task Information

To retrieve task information, perform the following tasks:

1. Include project files.

2. Create a TaskManagerQueryService and a TaskManager client API object.

3. Specify search criteria

4. Save file attachments.

Specify search criteria

To obtain information about a completed task, specify the user whom completed the task when setting connection properties required to invoke LiveCycle operations. That is, if you want to know what tasks tony blue completed, specify tonyb when defining connection settings.

You can also obtain information related to all tasks. For example, you can retrieve all completed tasks and determine the user who completed them (as opposed to retrieving tasks assigned to the user specified in the connection settings). To obtain all tasks, use an administrator account when defining connection settings. In addition, you can specify other search criteria such as the process name on which the task is based. For example, you can retrieve all tasks that are based on a specific process and then determine the users who completed them.

注意： This topic discusses retrieving all completed tasks and obtaining information such as the user who completed the task.

When retrieving all tasks, the result set may be very large. You can limit the result set using the Java and web service API.

Retrieve task information by using the Java API:

1. Include project files

   Include client JAR files, such as adobe-taskmanager-client-sdk.jar, in your Java project’s class path.

2. Create a TaskManagerQueryService and a TaskManager Client API object

   • Create a ServiceClientFactory object that contains connection properties.

   • Create a TaskManagerQueryService object by invoking the TaskManagerClientFactory object’s static getQueryManager method and passing the ServiceClientFactory object.

   • Create a TaskManager object by invoking the TaskManagerClientFactory object’s static getTaskManager method and passing the ServiceClientFactory object.

3. Specify search criteria

   • Create a TaskSearchFilter object by using its constructor.

   • Specify search criteria by invoking an appropriate method that belongs to the TaskSearchFilter object. For example, to specify the process on which a task is based, invoke the TaskSearchFilter object’s setServiceName method and pass a string value that specifies the process name.

   • Invoke the TaskSearchFilter object’s setAdminIgnoreAllAcls method and pass true to enable all tasks to be returned (not just the user who is specified in the connection settings).

4. Perform the search

   Search for tasks by invoking the TaskManagerQueryServiceService object’s taskSearch method and passing the TaskSearchFilter object. This method returns a java.util.List object where each element is a TaskRow object that represents a task that conforms to the specified search criteria.

   注意： The TaskSearch method is a generic way to search for tasks. In contrast, the TaskList method is meant as a specialized way to retrieve tasks. For example, using the TaskList method, you can get all tasks that are assigned to a specific user. (See Retrieving Tasks Assigned to Users.)

5. Iterate through the returned tasks

   • Create a java.util.Iterator object by invoking the java.util.List object’s iterator method. This object lets you iterate through the java.util.List instance to retrieve tasks.

   • Iterate through the java.util.List object to determine if there are tasks. If so, each element is a TaskRow instance.

   • Get the task identifier value by invoking the TaskRow object’s getTaskId method. This method returns a long value that specifies the task identifier value.

   • Retrieve task information by invoking the TaskManager object’s getTaskInfo method and passing the task identifier value.

Retrieve task information by using the web service API:

1. Include project files

   • Create a Microsoft .NET client assembly that consumes the TaskManager service WSDL. To create a proxy object that lets you invoke its operations by using Base64 encoding, specify this WSDL definition:

     http://localhost:8080/soap/services/TaskManagerService?WSDL

   • Reference the Microsoft .NET client assembly.

2. Create a TaskManagerQueryService and a TaskManager Client API object

   • Using the Microsoft .NET client assembly, create a TaskManagerQueryServiceService object by invoking its default constructor.

   • Set the TaskManagerQueryServiceService object’s Credentials data member with a System.Net.NetworkCredential value that specifies the user name and password value.

   • Using the Microsoft .NET client assembly, create a TaskManagerServiceService object by invoking its default constructor.

   • Set the TaskManagerServiceService object’s Credentials data member with a System.Net.NetworkCredential value that specifies the user name and password value.

3. Specify search criteria

   • Create a TaskSearchFilter object by using its constructor.

   • Specify search criteria by assigning a value to an appropriate data member that belongs to the TaskSearchFilter object. For example, to specify the process on which a task is based, assign a string value that specifies the process name to the TaskSearchFilter object’s serviceName data member.

   • Assign the value true to the TaskSearchFilter object’s adminIgnoreAllAcls data member to enable all tasks to be returned (not just the user who is specified in the connection settings).

4. Perform the search

   Search for tasks by invoking the TaskManagerQueryServiceService object’s taskList method and passing the TaskFilter object. This method returns an array of Objects where each element is a TaskRow object that represents a task that conforms to the specified search criteria.

5. Iterate through the returned tasks

   • Iterate through the Object array by creating a loop structure and for each element, cast the element value to a TaskRow instance.

   • Get the task identifier value by retrieving the value of the TaskRow object’s taskId data member.

   • Retrieve task information by invoking the TaskManager object’s getTaskInfo method and passing the task identifier value.
