Problem session Hibernate and JBoss

[tads]

Hi,

I´m using Hibernate 2.0.2, Oracle 8.1.7 and JBoss 3.2.3.

I have a method as follows:

// Obs.: the attribute dsTest of test is updated in called of
the method insertTest(..)


public void insertTest(Test test)
{
 Session session = null;
 Transaction tx = null;

 try
 {
 session = dataSource.openSession();
 tx = session.beginTransaction();

 session.update(test, session);

 // gets from database
 Test aux = session.load(Test.class, test.getIdTest());

 // if the object from database (aux) is different than test
 if (!test.getDsTest().equals(aux.getDsTest()))
 {
 session.update(teste.getOtherObject(), session);
 }

 tx.commit();
.
.
.

}

Out of JBoss, the method is correct, but in JBoss
The method updates the test and when gets from the database, the data
of test is already updated, but I didn´t commit the transaction.

What is wrong???
Somebody can help mee please?

Thanks

Ho, sorry... I forgot...

I was created a service in JBoss with MBean
and I´m using JTATransaction. It seems that it is using this Transaction Manager and the first sess.update was commited before
tx.commit().
