          "swimlaneInstance table and in taskinstance table are all "null"

          I did the same thing and it worked for me. What do you get when you call taskInstance.getActorId?

            when i execute taskinstance.getactorID() I got "null"
            My startworkflow code as follow:

            public long startWorkFlow(long workflowID, String userName)
 {
 log.debug("startworkflow " + workflowID + " start");
 long instanceID = -1;
 ProcessDefinition processDefinition = null;
 JbpmSession jbpmSession = jbpmSessionFactory.openJbpmSession();
 jbpmSession.beginTransaction();
 processDefinition = jbpmSession.getGraphSession().loadProcessDefinition(workflowID);


 ProcessInstance instance = new ProcessInstance(processDefinition);

 instanceID = instance.getId();

 // create a new taskinstance for the start task
 TaskInstance taskInstance = instance.getTaskMgmtInstance().createStartTaskInstance();
 System.out.println("taskInstance.getactorid="+taskInstance.getActorId());//

 instance.getContextInstance().setVariable("userName", userName);


 jbpmSession.getGraphSession().saveProcessInstance(instance);

 jbpmSession.commitTransaction();
 jbpmSession.close();
 return instanceID;
 }
