How to register user and group dynamically in jBPM 6.2?

[awizenm]

Hi all,

In jBPM 5 to register a user you would do this like that (from user guide 5.4 Chapter 13):

EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task");

TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener());

TaskServiceSession taskSession = taskService.createSession();

// now register new users and groups

taskSession.addUser(new User("krisv"));

taskSession.addGroup(new Group("developers"));

I want to flexible create and handle new user at the runtime.

How to register user and group dynamically in jBPM 6.2?

I assume a new user should find his way to the OrganizationalEntity table. But how?

Is there a way to create and persist the UserImpl directly - as User is now an interface?

Does jBPM 6 support dynamic user creation and handling at all?

ok, playing around directly with UserImpl is not a good idea.

Registering a user (adding a user) to the task seems also to be an obsolete concept in jBPM 6.2.

The solution to my problem is indeed adding the bpmn2:potentialOwner element to bpmn2 like in the Evaluation.bpmn example. Then passing arbitrary user as a parameter on process start in Java code.

However, to be able to give the task to any user I had to use my own simple UserGroupCallback in the test class:

Here is the constructor:

public MyJbpmJUnitBaseTestCase(boolean arg0, boolean arg1) {
    super(arg0, arg1);
    userGroupCallback = new UserGroupCallback() {

        @Override
        public List<String> getGroupsForUser(String userId, List<String> groupIds, List<String> allExistingGroupIds) {
            List<String> groups = new ArrayList<String>();
            groups.add("myGroup");
            return groups;
        }

        @Override
        public boolean existsUser(String userId) {
            return true;
        }

        @Override
        public boolean existsGroup(String groupId) {
            return true;
        }
    };
}
