I am testing BMP with Jboss. And I ran into transaction problems that I could not find any similar info on Google. I am using Hibernate 2, jboss 3.2.3 and postgresql 7.3. I am new to Hibernate/Jboss and I have no clue how to handle the error.

And this is the transaction attribute in ejb-jar

<assembly-descriptor>
<container-transaction>

<ejb-name>TuserBMP</ejb-name>
<method-intf>Local</method-intf>
<method-name>*</method-name>


<ejb-name>TuserBMP</ejb-name>
<method-intf>Remote</method-intf>
<method-name>*</method-name>

<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>

And this is the code for saving using hibernate

session = sessionFactory.openSession();
transaction = session.beginTransaction();
session.save(anUser, anUser.getUserid());
transaction.commit();
session.close();


I appreciate any glimpse of light that can show the way.


thanks
