Hi,

I doing it the same way but not directly. I am not registering my handler with kession. But the completeWorkItem(workItemId, result) i am calling on the same session. The call to this method is not inside the handler but inside an ejb that is called from the new thread that i am calling.

My workItemHandler is as follows:

public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {


                    final String operation = (String) workItem.getParameter("Operation");


                    final WorkItem internalWorkItem = workItem;
                    final WorkItemManager internalWorkItemManager = manager;


                    new Thread(new Runnable() 
                    {
                                   public void run() 
                                   {

               Map<String, Object> inParams = internalWorkItem.getParameters();
                                                                           inParams.put("workItemId",Long.valueOf(internalWorkItem.getId()));

                                                                           inputParams.add((Serializable)inParams);

                                                                      try
                                                                      {
                                                                                     results = EJBCallLookUP.call(operation, inputParams);
            }
           catch(Exception e)
          {
                    e.printStackTrace();
          }

        }
  }).start();
}

in the EJBCallLookUP.call I am looking up the ejb for the operation and calling the method with operation name. Inside that operation i am calling the completeWorkItem(...) with the session.
