[jboss-user] [JBoss Seam] - Pb Initializing database on app startup with postInitializat
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") :

Any help ?
