jbpm5.4 register LocalHTWorkItemHandler,transaction error!!
my code below,i wouldn`t to use hunman task server, so i register LocalHTWorkItemHandler,but not success。Beside，
what the benefit if deloy the human task server alone.
if("Local".equalsIgnoreCase(starge)){
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task");
org.jbpm.task.service.TaskService taskService = new org.jbpm.task.service.TaskService(
emf, SystemEventListenerFactory.getSystemEventListener());
LocalTaskService localService=new LocalTaskService(taskService);
LocalHTWorkItemHandler workItemHandler= new LocalHTWorkItemHandler(localService, ksession,OnErrorAction.RETHROW);
workItemHandler.connect();
workItemHandler.setLocal(true);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",workItemHandler);
UserGroupCallbackManager manager = UserGroupCallbackManager.getInstance();
if (!manager.existsCallback()) {
UserGroupCallback userGroupCallback = getInstance("org.jbpm.task.identity.DefaultUserGroupCallbackImpl");
manager.setCallback(userGroupCallback);
}
System.out.println("Task service startup completed successfully !");
//mina,HornetQ
}else{
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
new org.jbpm.process.workitem.wsht.AsyncHornetQHTWorkItemHandler("jbpmConsoleHTHandler",
TaskClientFactory.newAsyncInstance(starge,"taskClient",false) , ksession, org.jbpm.task.utils.OnErrorAction.LOG));
}
when start process by the "Local" condition throw below exception,but the "else" condition is OK
