If you are using EJB3 I recommend using a persistence.xml file. such as... <persistence-unit name="metadata"> <jta-data-source>java:/it</jta-data-source> org.hibernate.ejb.HibernatePersistence </persistence-unit> In your ejb instead of trying to create a jdbc connection use the annotation in your ejb @PersistanceUnit(unit="metadata") EntityManagerFactory factory in your method you can access the query object such as EntityManager em = factory.createEntityManager Query query = em.whatYouNeedToDo... Or if you need more advance features of the Hibernate Query object //in your ejb or where you need it. private EntityManagerFactory factory = new HibernatePersistence().createEntityManagerFactory(GUI, new HashMap()); in your method Session session = session = ((HibernateEntityManagerFactory)factory).getSessionFactory().getCurrentSession(); HTH View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044697#...
