Hi all,

I'm Using JBPM5.2.final in a seam 2 application all running under jboss 5.1 SA.

When a use LocalTaskService as following : 
to connect the service : 

public void connect() {
            if (service == null) {
                org.jbpm.task.service.TaskService taskService = HumanTaskService.getService();                
                service = new LocalTaskService(taskService.createSession());
            }
....


and I register the human task :

           TaskService taskService = HumanTaskService.getService();     
            SyncWSHumanTaskHandler handler = new SyncWSHumanTaskHandler(new LocalTaskService(taskService.createSession()), ksession);   
            ksession.getWorkItemManager().registerWorkItemHandler("Human Task", handler);


But when a start my process instance and create a human task I get then the following exception (*A JTA EntityManager cannot use getTransaction()*) : 
I'm using jboss transaction manager

12:33:59,014 ERROR [STDERR] Caused by: java.lang.IllegalStateException: A JTA EntityManager cannot use getTransaction()
12:33:59,014 ERROR [STDERR]     at org.hibernate.ejb.AbstractEntityManagerImpl.getTransaction(AbstractEntityManagerImpl.java:324)
12:33:59,014 ERROR [STDERR]     at org.jbpm.task.service.TaskServiceSession.taskOperation(TaskServiceSession.java:442)
12:33:59,014 ERROR [STDERR]     at org.jbpm.task.service.local.LocalTaskService.start(LocalTaskService.java:224)
12:33:59,014 ERROR [STDERR]     at com.atriumnetwork.jbpm.LocalTaskManager.completeTask(LocalTaskManager.java:96)


I checked in the sources ther were tow options for TransactionType: default and local-JTA

So I tried to set the transaction type to local-JTA :

taskSession.setTransactionType("local-JTA");


This is working when I start my process  but  when  execution other human tasks I get : *No active JTA transaction on joinTransaction call exception*
*
*

    at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:122)


is there another option for the transaction type ??  

any help will be very appreciated
