I had everything working great in my WebSphere Application Server 6.0 instance with DB2 V8.1 and Hibernate 3 with a non-XA data source using WAS's JTA. Rollbacks were working fine in my stateless session beans whenever an exception was thrown.
However, due to a limitation in WAS, I needed to change my data source to an XA type, which I did and verified that the connection was working okay. Now I am still able to run queries, update entities, etc, via Hibernate and the XA based data source, but rollbacks are not working and Exceptions are not being handled as they should in my stateless session beans.
I noticed that when one of my DAOs caught a valid RuntimeException from Hibernate and threw a custom Exception to the calling stateless session bean, instead of the bean’s exception block catching the exception from the DAO, it went directly to the finally block. In addition,
made thus far – major issue. I also noticed a warning reported from Hibernate’s AbstractBatcher occasionally when a session closes, stating that I may have left a result set open, but from what I read (can’t find the article right now), it was simply an issue in the log and shouldn’t be a concern.
The lack of roll-backs, even when I issue a session.getTransaction().rollback(), does concern me though. Do I need to make further mods to my Hibernate config file below? Am I missing something?
