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();

Subject: Re: [rules-users] Human Task Example
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.
