I'm using jboss 4.0.1 and hibernate 2.1

I have a stateless session bean which accesses a DAO class which has heibernate code to insert, update... I noticed that if in this DAO class I use hibernate transactions, with transaction.begin() and transaction.commit() when the transaction.commit() line is executed the database is not updated.
Why that happens? Shouldn't the data be commited to the database when commit is executed?

Other thing I tried was to use JBoss' UserTransaction class but it also didn't work. How can I be sure that when the transaction.commit() is executed the database is really updated?

Thank you

Kelly.

Debug level Hibernate log excerpt:

SLSB can use JTA/CMT if you have configured the correct Transaction semantics for SLSB method(s), eg, tx required. If you do this then you do not need to call any Transaction API methods since the container will manage it. You do need to provide the rollback hint as per CMT standards if an error occurs or the situation requires a rollback.
