To add the users and groups
Hi community
I have a requirement that i want to add my own users and groups to the jBPM and I want to do this dynamically. i tried with something like,
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task");
TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener());
TaskServiceSession taskSession = taskService.createSession();
// now register new users and groups
Group g = new Group();
taskSession.addUser(new User("userA"));
taskSession.addGroup(new Group("groupA"));
When i run this code i got some exception,
javax.persistence.PersistenceException: No Persistence provider for EntityManager named org.jbpm.task
