Hi,
I have a problem with getting bean managed transaction or more appropriately
user managed transaction to work on my Session Bean (EJB3 specs.)
I have a session bean with the EntityManager "em" already defined and I have a
method xxx() which is suppose to rollback all which persistence when one of
them failed.
I tried to obtain the EntityTransaction by calling:
EntityTransaction trxn = em.getTransaction();
try
{
trxn.begin();
//do something...
trxn.commit();
}
catch(Exception ex)
{
trxn.rollback();
}
Unfortunately, JBoss throws IllegalStateException while calling
em.getTransaction(). May I know how do I configure the session bean to be able
to handle user managed transaction instead of container managed transaction
(like the old days where we could define that in the ejb-jar.xml)? I'm running
on JBoss 4.0.4RC1.
Any help will be greatly appreciated. Thank you.
