I'm attempting to make use of the EntityManager in a non-managed environment, however, I'm receiving a HibernateException with a description of "No TransactionManagerLookup specified" when I attempt to get an object using EntityManager.find(). Does anyone know what might be the problem?

Hibernate version: hibernate-3.1alpha1, hibernate-annotations-3.1beta3, hibernate-entitymanager-3.1beta1

Mapping documents:

persistence.xml


hibernate.cfg.xml



Code between sessionFactory.openSession() and session.close():

EntityManagerFactory emf = Persistence.createEntityManagerFactory("bb_bb60");
EntityManager em = emf.getEntityManager();
CourseRole cr = em.find(CourseRole.class, "S");

getEntityManager() is not allowed in a non managed environment

Heh, thanks Emmanuel, good eye. I mistakenly was using getEntityManager() instead of createEntityManager(). It works now. Thanks.
