Hi,
My environment : Jboss3.2.3, Hibernate2.1.2 , windows-xp( this o/s is only for development env.)

High level architectural flow

Stateless session bean -> Hibernate -> my data source ->database

1) Data source : local-tx-datasource
I

If you use CMT or JTA Transactions, don't forget to set hibernate.transaction.manager_lookup_class, hibernate.transaction.factory_class and jta.UserTransaction

In session beans, I do not use the Hibernate transaction. Instead, I get a session from the factory bound to JNDI, use it and then flush and close the session. Exceptions cause a roll back.

I believe (someone please confirm) that the Hibernate session from the factory bound to JNDI is tied to the session bean transaction.

So don't use Hibernate transactions in session beans.
