    Pb Initializing database on app startup with postInitializat

    Zalder R Newbie

      I launch a method on application startup using the org.jboss.seam.postInitialization event. It work fine except if I access the database (and I need to) :

      using seam managed entity manager :

      @In
       private EntityManager em;
      
      @Observer("org.jboss.seam.postInitialization")
      private void setupAFewThings() throws ComentSystemException {
       MyObject w = new MyObject() ;
       w.setName("test_name") ;
       em.getTransaction().begin();
       em.persist(w) ;
       em.getTransaction().commit();
      }


      or manually creating a new entity manager like this :

      @Observer("org.jboss.seam.postInitialization")
      private void setupAFewThings() throws ComentSystemException {
       MyObject w = new MyObject() ;
       w.setName("test_name") ;
       EntityManagerFactory emf = Persistence.createEntityManagerFactory("myDatabase");
       EntityManager em = emf.createEntityManager();
       em.getTransaction().begin();
       em.persist(w) ;
       em.getTransaction().commit();
      }


      I get the same error ("java.lang.IllegalStateException: JTA EntityManager cannot access a transactions") :
      16:26:18,530 ERROR [[/coment_demo]] Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.jboss.seam.servlet.SeamListener
