Post-Update Listener: not saving new Objects ?

Hello,

i'm using an post-update listener with hibernate 3.2.1 GA inside jboss. Have configured correctly persistence.xml and session binding to jndi.

Inside this listener i create a new audit-entry. Then i try to persist this transient object via following code:

Code:

  private void saveNewObjectFromWithinEventListener( Object myObject ) {
        try {
            InitialContext ctx = new InitialContext();
            SessionFactory factory = (SessionFactory) ctx.lookup("java:/hibernate/SessionFactory");
            factory.getCurrentSession().save(myObject);
        } catch (NamingException e) {
            throw new HibernateException(e);
        }

But the Audit entry get's never persisted in the database. No Exception is thrown. Is it impossible to create and persist objects inside an listener ?

you cannot use a session inside it's own event listener

But is it possible to use another (new) Session inside the listener? For example via:

Code:

factory.openSession(factory.getCurrentSession().connection())
               .persist(myObject);      

Will this work ?

Addition: it seems that even the way via

Code:

factory.getCurrentSession().save(myObject);

is working. I "only" explicitly have to flush() the session.

a new session on the connection is the safe way to do it
