Hello 
   I have some problem with my database connection.
   When i want to persist my object to my database, the server don't throw an exception but it don't insert into my table.
   And when i see my debug log, it says 

14:50:21,848 DEBUG [org.hibernate.engine.transaction.internal.TransactionCoordinatorImpl] (http-localhost-127.0.0.1-8080-1) Skipping JTA sync registration due to auto join checking

  public static EntityManager getEntityManager()

    EntityManagerFactory emf;
    try

      emf = (EntityManagerFactory)InitialContext.doLookup("java:jboss/EntityManagerFactory"); //$NON-NLS-1$
      if (emf != null)
      {

      }
      else
      {

      }
    }
    catch (final NamingException e)
    {
      throw new IllegalStateException("EntityManagerFactory cannot create entity manager"); //$NON-NLS-1$
    }
    return em;
  }
 
 
 
 


     It's an datasources error or and bad persistence.xml ?

Thanks
