[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - em.persist(entity) ignores transaction

I am using JBoss 4.0.5GA and mysql 5.0 database. 

in web tier: 

UserTransaction userTransaction = 
  | (UserTransaction)new InitialContext().lookup("java:comp/UserTransaction"); 
  | userTransaction.begin(); 
  | // in session bean, em is EntityManager 
  | em.persist(entity); 
>From mysql console, the entity was created immediately in database(mysql). 

I expected it to be created after calling 

in web tier. 

For debugging, I added the following code around em.persist(entity): 

  | Session session = ((HibernateSession)em).getHibernateSession(); 
  | Transaction t = session.getTransaction(); 
  | t.begin(); 
  | em.persist(entity); // the enitty was created immediately in database (see from mysql console) 
  | t.rollback(); 
  | boolean committed = t.wasCommitted(); // value is false 
  | boolean rollback = t.wasRolledBack(); // value is false 
after the rollback, the created entity did not roll back. The transaction was ignored. 

Is this a bug? How to use UserTransaction with entityManager? 

Thanks for any help!
