Websphere Deployment Issue (Hibernate and Oracle)

[Parsu nurani]

Hello Kyle Please Help: I have spent a long time with this issue and am under tight timelines...

I have an web application (Non EJB) that based on servlets, JSP, struts, and Hibernate, and Oracle 9i. The application works fine in Tomcat 4.1.x. However when I deploy in Websphere (I am deploying a manually created war file without using WSAD) I notice the following:

1) All reads from the database are working fine
2) Inserts work first time and fail on second time and subsequent times
3) I see the following error messages:

javax.servlet.ServletException: LocalTransaction rolled-back due to setRollbackOnly
at
com.ibm.ws.webcontainer.webapp.WebAppTransactionCollaborator.postInvok (WebAppTransactionCollaborator.java:224)
at
com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.dispatch(WebAppRequestDispatcher.java:671)
...

It is accompanied by:

WLTC0033E: Resource jdbc/cdb rolled back in cleanup of unresolved LocalTransactionContainment.

and:

WLTC0032E: One or more resources rolled back. An unresolved LocalTransactionContainment had an unresolved action of rollback

Questions:

1) Why is WAS trying to rollback transaction?
2) How can I disable this so I have full control of transaction?
3) Has anyone deployed a simple webapp (Non-EJB) app using hibernate, WAS, and Oracle? If so please atleast guide me...

Thanks,
