[jboss-user] [EJB 3.0] - How to treat OptimisticLockException?

[fabricio.lemos]

In my application I want to show a message to the user when he is working with stale data.

I implemented Optimistic Locking, but the client application receives a JBossRollbackException instead of OptimisticLockException.

Here is the stack trace:
