Session closed exception
Hi,
We have a Weblogic portal based application using Spring, Hibernate. We now are trying to use JBPM in the application. Have created seperate db schema for jBPM and a different datasource as well.
What I am doing is calling another class (JBPM Action Handler) from my service class and coming back again to my service class.
Inside JBPM class, I don't use any entity from the existing application, but when I return to my service class and try to update an entity this exception occurs.
JBPM code snippet is sth like:
---------------------
JBPMWorkFlowUtil utilEngine = new JBPMWorkFlowUtil();
utilEngine.beginTransaction();
ProcessInstance processInstance = utilEngine.getProcessInstance(Constants.CREATE_OPPORTUNITY, opportunityVO.getProcessInstanceId());
utilEngine.setVariable(processInstance, Constants.REQUEST_RESOLUTION, opportunityVO.getRequestResolutionStatus());
utilEngine.signal(processInstance);
utilEngine.saveProcessInstance(processInstance);
String nextAction = (String) utilEngine.getVariable(processInstance, Constants.NEXT_ACTION);
utilEngine.endTransaction();
---------------------
utilEngine.endTransaction(); does closeContext as well.
We are using a different hibernate.cfg.xml for jbpm i.e. different session-factory which in effect means 2 different sessions, one for existing application entities and one for jbpm entities.
I don't know the reason why this session is getting closed, as I am not doing it in my code anywhere.

Your early response is very much appreciated.
