In a Roll back EJB exception is thrown

[Ransika deSilva]

Hi all,
I am using JPA with hibernate in a stateless session been and and that bean is called from a servlet. I am using CMP and when ever a roll back occurs it is thrown back to the servlet as a EJBException. My problem is, since EJBException is thrown for other reasons as well, how to figure out whether it was thrown for a roll back or some other reason. At the same time, can't we catch the Transaction aborted exception in the EJB. I tried using RuntimeException in the catch clause, but it didn't work. Anticipating a reply. Thanks.

That's the wrong way roung, isn't is? The EJBException causes a transaction to be rolled back, not a rollback causing an EJBException? Or am I misunderstanding you?

What other reason causes it to be thrown?

Hi, thanks for the reply. Yes good point, EJBException is thrown and then roll back happens. That's the way it should be. But the problem I am having is, when I try to add a record with the same primary key, I get this problem. I really don't know what to do, meaning, what exception which I need to capture. I am using JPA with hibernate.

Thanks and expecting a reply soon.
