You  can manually add users via the OrganziationalEntity table:

 

User, Administrator

User, myuser

Etc.

 

I am doing the following to start the task server:

 

        Environment env = KnowledgeBaseFactory.newEnvironment();

        taskServerEntityManagerFactory = Persistence.createEntityManagerFactory("org.drools.task");

        env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, taskServerEntityManagerFactory);

       

        taskService = new TaskService(taskServerEntityManagerFactory, SystemEventListenerFactory

                .getSystemEventListener());

       

        server = new MinaTaskServer(taskService);

        Thread thread = new Thread(server);

        thread.start();

I did see that I need to populate users, but I didn't at first seen any instructions on how to do so. Reading more carefully, I think I see how to do it now, i.e. by calling "addUser()". I'll give that a try a little later today. Another thing that may give me a problem is that I didn't know what the second argument should be to the TaskService() constructor below. The documentation shows only one argument, but it seems that there is no one argument constructor anymore. Any help with that? Really appreciate your help and time! -Chuck

private static void startTaskService()

        {

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

               TaskService taskService = new TaskService(emf,null);

               MinaTaskServer server = new MinaTaskServer( taskService );




               Thread thread = new Thread( server );

               thread.start();

        }

I see that problem before. It means that you need to populate some users first. Insert in the database an administrator user before running the process.

I did manage to put some code together but I didn't feel from reading the
documentation that I knew exactly what I was doing. I think it would be very
helpful and many questions would be avoided if a worked out example could
be provided with the drools distribution. Anyway, I really appreciate your
help. The error I got is indicated below.
