In a legacy project I need the SessionFactory.

My persistence.xml:

<persistence-unit name="User">

  <jta-data-source>java:/OracleDS</jta-data-source>

  <exclude-unlisted-classes>true</exclude-unlisted-classes>

  <properties>

  <property name="hibernate.ejb.cfgfile" value="/user/hibernate.cfg.xml" />

  <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />

  <property name="hibernate.transaction.factory_class"

  value="org.hibernate.transaction.JTATransactionFactory" />

  <property name="hibernate.transaction.manager_lookup_class"

  value="org.hibernate.transaction.JBossTransactionManagerLookup" />

  <property name="hibernate.current_session_context_class"

  value="jta" />

  <property name="hibernate.session_factory_name" value="java:/hibernate/UserSessionFactory" />

  </properties>

</persistence-unit>

In the EJB3 I use it like this:

@Resource(mappedName = "java:/hibernate/UserSessionFactory")

private SessionFactory sf;

private Session getSession() {

  return sf.openSession();

}

But it seems that there is no transaction active as there are no update statements generated.

What's wrong?
