[jboss-user] [EJB 3.0] - javax.resource.ResourceException: Transaction is not active

Hi Im getting javax.resource.ResourceException: Transaction is not active when this code executes. (em = EntityManager) | public getUserGoupById(Long id) { | Query dbQuery = em.createQuery("from UserGroup where id = :id"); | dbQuery.setParameter("id", id); | UserGroup ug = (UserGroup) dbQuery.getSingleResult(); | return ug //Here the exception will be thrown. | } | In debugmode Im able to see that ug is what Im looking for (right Id & name). But every time I trie to return it the exception will show. I use the same bean for getUserById(Long id), and it works fine. What could be wrong in the usergroup-case? Thanks!
