[jboss-user] [jBPM] - Transaction Problems jBPM5

roxy1987 [https://community.jboss.org/people/roxy1987] created the discussion "Transaction Problems jBPM5" To view the discussion, visit: https://community.jboss.org/message/796412#796412 -------------------------------------------------------------- Hi community, I am stuck with an exception and I cant get out of it. I have 3 separate modules , a dynamic web project for view, EJB project for EJB and a simple jbpm java project. I use JSFs and session scope manage beans to call the EJBs using a service locator which calls the BPM APIs. When I try to complete the task it gives me the following exception. Any clue why I get the transaction exception. The exact same piece of code seems to work fine in a servlet container. The code that I use is public static void completeTask(long taskId, String userId) throws Exception { client = new TaskClient(new MinaTaskClientConnector("org.drools.process.workitem.wsht.WSHumanTaskHandler", new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));     boolean connected = client.connect(ipAddress, port);     if (!connected)     {      throw new IllegalArgumentException("Could not connect task client");     }     BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();     ContentData contentData = null;   try   {    client.complete(taskId, userId, contentData, responseHandler);    responseHandler.waitTillDone(5000);   }   catch(Exception e)   {    BpmExceptionHandler.handleException(e);   }   finally   {    disconnect();   } }   And the stack trace is :                                  javax.ejb.EJBException: Invalid
