My jBPM5.2 doesn't work! Like this......

[c1269355458]

hi, all.

JPA and MinaTaskServer are working well.

my action is like this:

	StatefulKnowledgeSession session = null;
		try {
		session = JbpmAPIUtil.createKnowledgeSession("bpmn/HumanTask.bpmn");
		session.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
		} catch (Exception e) {
		e.printStackTrace();
		}
		Map<String, Object> params = new HashMap<String, Object>();
		params.put("userId", "krisv");
		params.put("description", "Need a new laptop computer");
		ProcessInstance instance = session.startProcess("com.sample.humantask", params);
		System.out.println("\n\n start " + instance);

and error:

Hibernate: insert into SessionInfo (lastModificationDate, rulesByteArray, startDate, OPTLOCK) values (?, ?, ?, ?)

Hibernate: insert into ProcessInstanceInfo (lastModificationDate, lastReadDate, processId, processInstanceByteArray, startDate, state, OPTLOCK) values (?, ?, ?, ?, ?, ?, ?)

Hibernate: insert into WorkItemInfo (creationDate, name, processInstanceId, state, OPTLOCK, workItemByteArray) values (?, ?, ?, ?, ?, ?)

Make sure that you have the Administrator user inside your Human Task user table. By the way, what is "example", make sure that you have an user called that as well if you want to asign something to it.

Cheers

[c1269355458]

Thanks.

Thear is a row in the table like this:

DTYPE ID

User    administrator

[salaboy21]

I think it should be "Administrator", what about "example"??

Cheers

[c1269355458]

"example" is the Database'name.

I have change "administrator" to "Administrator", but it doesn't work always!

Cheers

[salaboy21]

Did you check that all the users that are trying to be assigned exists in the database?

Please confirm.

[c1269355458]

I promiss it.

I have added all the users when MinaTaskServer class started.

TaskService taskService = new TaskService(emfTask, SystemEventListenerFactory.getSystemEventListener());

                              /*

                               * Add the required users

                               */

                              TaskServiceSession taskSession = taskService.createSession();

                              taskSession.addUser(new User("Administrator"));

                              taskSession.addGroup(new Group("Stuff"));

                              taskSession.addUser(new User("kvsi"));

                              taskSession.addGroup(new Group("Manager"));

                              taskSession.addUser(new User("john"));

                              taskSession.addUser(new User("krisv"));

                              /* Start Mina server for HT */

                              MinaTaskServer server = new MinaTaskServer(taskService);

                              Thread thread = new Thread(server);

                              thread.start();

[c1269355458]

All users is exists in the database.

thinks.

[salaboy21]

Can you show us please how are you doing the assignments?

Cheers

servlet listener:

			EntityManagerFactory emfTask = Persistence.createEntityManagerFactory("org.jbpm.task");
			// (EntityManagerFactory) Constants.ctx
			// .getBean("entityManagerFactory");
			TaskService taskService = new TaskService(emfTask, SystemEventListenerFactory.getSystemEventListener());
			/*
			* Add the required users
			*/
			TaskServiceSession taskSession = taskService.createSession();
			taskSession.addUser(new User("Administrator"));
			taskSession.addGroup(new Group("Stuff"));
			taskSession.addUser(new User("kvsi"));
			taskSession.addGroup(new Group("Manager"));
			taskSession.addUser(new User("john"));
			taskSession.addUser(new User("krisv"));
			/* Start Mina server for HT */
			MinaTaskServer server = new MinaTaskServer(taskService);
			Thread thread = new Thread(server);
			thread.start();
			System.out.println("Server started ...");

struts Action

  StatefulKnowledgeSession session = null;

                    try {

                              session = JbpmAPIUtil.createKnowledgeSession("bpmn/apply-leave.bpmn");

                              session.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());

                    } catch (Exception e) {

                              e.printStackTrace();

                    }

                    Map<String, Object> params = new HashMap<String, Object>();

                    params.put("manager", "john");

                    ProcessInstance instance = session.startProcess("bpmn.applyLeave",params);

                    System.out.println(" \n\n process start : " + instance);

the other action:

List<TaskSummary> tasks = JbpmAPIUtil.getTasksAssignedAsPotentialOwner("john");

                    System.out.println(" size of tasks " + tasks.size());

                    for (TaskSummary ts : tasks) {

                              System.out.println("\n\n  ts :  " + ts);

                    }

bpmn:

actorId : #{manager}

thanks very much!

[salaboy21]

Is "manager" defined as a process variable?

Cheers

[c1269355458]

Yes.

[salaboy21]

I notice that you are starting two different processes:

ProcessInstance instance = session.startProcess("bpmn.applyLeave",params);

and

ProcessInstance instance = session.startProcess("com.sample.humantask", params);

Which one is the failing one?

It's impossible to help if we don't have accuarate data to look at. Can you please create an isolated test that shows the problem and share the maven project to run it?

Cheers
