Hibernate version: 2.1.5
JBoss version: 4.0.0

I configure Hibernate as an mbean service with the following:
Code:
   <mbean code="net.sf.hibernate.jmx.HibernateService" name="jboss.jca:service=HibernateFactory, name=HibernateFactory">
       <depends>jboss.jca:service=RARDeployer</depends>
<!--       <depends>jboss.jca:name=PostgresDS, service=LocalTxCM</depends> -->
       <attribute name="MapResources">
           test/web/project/beans/Event.hbm.xml, test/web/project/beans/User.hbm.xml
       </attribute>
       <attribute name="JndiName">java:/hibernate/HibernateFactory</attribute>
       <attribute name="Datasource">java:PostgresDS</attribute>
       <attribute name="Dialect">net.sf.hibernate.dialect.PostgreSQLDialect</attribute>
       <attribute name="TransactionStrategy">net.sf.hibernate.transaction.JTATransactionFactory</attribute>
       <attribute name="TransactionManagerLookupStrategy">net.sf.hibernate.transaction.JBossTransactionManagerLookup</attribute>
       <attribute name="UserTransactionName">UserTransaction</attribute>
   </mbean>

The I created a stateful session bean, which is responsible for the data in/out of the persistent storage. And inside the session bean, it basically uses normal hibernate stuff. So the interface would provide something like that:
Code:
  public void addSomething(Object something) ...

And in that method:
Code:
        try {
            Session session = sessionFactory.openSession();
            Transaction tx = session.beginTransaction();

            User theUser = new User();
            theUser.setFirstname(firstname);
            theUser.setLastname(lastname);
            theUser.setAge(age);

            id = (Long) session.save(theUser);

            tx.commit();
            session.close();
            }
        } catch (HibernateException e) {
            log.error("storeUser() - Exception : " + e);
        }


SessionFactory is retrieved via JNDI. A servlet can invoke the method in the ejb and everything is working fine.

Now, I want to do batch insert instead of one-by-one. So the ejb provides two more methods:
Code:
    public void beginTransaction();
    public void commitTransaction();

And the work to open session is being done in beginTransaction(), and the commit and close session is in commitTransaction(). In this case, it just won't work, with the following error. Is there anything I did wrong?
