When i create a jbpm project with eclipse,and creat taseservice code in main method, and all the packages has include in the project.But when run the project , a error occured at the red line, like this:
Exception in thread "main" java.lang.IllegalArgumentException: Named query not found: UnescalatedDeadlines
at org.hibernate.ejb.AbstractEntityManagerImpl.createNamedQuery(AbstractEntityManagerImpl.java:108)
at org.jbpm.task.service.TaskService.<init>(TaskService.java:109)
at org.jbpm.task.service.TaskService.<init>(TaskService.java:92)
at org.jbpm.DemoTaskService.main(DemoTaskService.java:93)
the mian method code like this:
| | EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task"); |
| |
|
| | TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener()); |
| | MinaTaskServer server = new MinaTaskServer( taskService ); |
| | Thread thread = new Thread( server ); |
| | thread.start(); |
the persistence.xml like this:
