Hi,
I had something to this effect in my "todo list":
http://blog.vacs.fr/index.php?post/2010/06/27/Fault-tolerant-EJB-interceptor%3A-a-solution-to-optimistic-locking-errors-and-other-transient-faults
It's an interceptor which catches exceptions. You could use it to
rethrow your own exception when an optimistic lock exception occurs.
disclaimer: I haven't tried it yet.

There is no trivial way to get that in the client cause the spec requires
it to be wrapped.
As the exception is thrown during commit (flush at least), you can in the
business method (ie. the session bean method) force a em.flush() to
propagate the persistence context to the database and get all relational
constraints validated by the database.
Around the flush statement, you can catch the Optimistic Lock exception and
throw a business exception.
That's the best way from a design point of view to do and to deal with such
a situation.

Hi,
I am trying to migrate an application which works on Glassfish 3.1.2.2to
TomEE 1.5.
The application calls each component like this : JSF -> CDI -> Stateless
EJB -> JPA -> DB
On the Glassfish, a program(CDI) in the web tire can handle the
“OptimisticLockException” with the following code successfully.
:
} catch (Exception e) {
if (e.getCause() instanceof
javax.persistence.OptimisticLockException) {
:
However, on the TomEE 1.5, we got javax.transaction.RollbackException
instead of
javax.persistence.OptimisticLockException.
How can I catch “OptimisticLockException” in the CDI?
