I am running the HumanTaskService in JBoss and its persistence is done in my Oracle db.
but when I run process with "UserTasks" in it, and it successfully runs through
end.
*My ques is when I call the "taskClient.getTasksAssignedAsPotentialOwner(user,
"en-UK", taskSummaryHandler);"*
*then from where it picks up the data,*
*1. from session?*
*2. or from db?*
If it picks it from *session*, then please tell me how i persisted the session of the
whole "ProcessInstance" in my db and picks the pending task from there.
Below is the code used to pick and complete the "UserTask".
TaskClient taskClient = new TaskClient(new
MinaTaskClientConnector("MinaConnector",
new
MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
taskClient.connect("127.0.0.1", 9123);
BlockingTaskSummaryResponseHandler taskSummaryHandler = new
BlockingTaskSummaryResponseHandler();
taskClient.getTasksAssignedAsPotentialOwner(user, "en-UK",
taskSummaryHandler);
TaskSummary task1 = taskSummaryHandler.getResults().get(0);
BlockingTaskOperationResponseHandler taskOperationHandler = new
BlockingTaskOperationResponseHandler();
taskClient.start(task1.getId(), user, taskOperationHandler);
taskClient.complete(task1.getId(), user, null, taskOperationHandler);
Regards.

For retrieving the human task information you are using the Human Task services that is
running here:
|
| | taskClient.connect("127.0.0.1", 9123); |
|
|
That service has its own database decoupled from the session database to store the
information about the human tasks. When you connect to that server and call the
getTasks... or start.. it go to that database and niteracts with the information there.
Cheers

Actually I start the "HumanTaskService" with my own in JBoss using the below
code:-
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.jbpm.task");
TaskService taskService = new TaskService(emf,
SystemEventListenerFactory.getSystemEventListener());
TaskServiceSession taskSession = taskService.createSession();
Map vars = new HashMap();
Reader reader = new InputStreamReader( StartTaskService.class.getResourceAsStream(
"LoadUsers.mvel" ) );
Map<String, User> users = ( Map<String, User> ) eval( reader, vars
);
for ( User user : users.values() ) {
taskSession.addUser( user );
}
reader = new InputStreamReader( StartTaskService.class.getResourceAsStream(
"LoadGroups.mvel" ) );
Map<String, Group> groups = ( Map<String, Group> ) eval( reader, vars
);
for ( Group group : groups.values() ) {
taskSession.addGroup(group);
}
MinaTaskServer server = new MinaTaskServer(taskService);
Thread thread = new Thread(server);
thread.start();
taskSession.dispose();
System.out.println("Task service started correctly !");
System.out.println("Task service running ...YAHOOO..");
and I make the changes in jbpm-human-task-5.1.0.Final.jar's Persistence.xml, so it now
points to my db.
And with this all the task related imformation is stored in my db and I can see it
properly.
But the only thing is: if a "Process" having "3UserTasks" then on
starting the Process, the db can contain only the imformation about the "first
pending" but not others 2.
But as soon as I complete the first task then its status changes to pending and then
"second pending user" shows in my db.
So please tell me how I store "session db" to my own db.
