Hi,
I'm using JBoss 4.0. I have a container-managed stateful session bean which
will call a stateless session bean for some business logics. What I'm trying to
do is to simulate a transaction rollback scenario to see my beans' behaviour.
Something I don't understand, when I get a
"TransactionRolledbackLocalException" in the stateless session bean, the caller
bean (stateful) will do an activation when I re-invoke the method call. I've
simulated this scenario few times, and each time, it gives the same result.
From the log files, it didn't show the stateful session bean passivated. It
only shows attempting to activate.

==========================================
Any idea why is this happened?
My own thought is, do correct me if I'm wrong, the statelss session bean by
default is using the same tx as the stateful session (for container-managed)
bean. When "TransactionRolledbackLocalException" occurred, both beans is
marked as "rollback only", hence caused the stateful session gone?
My objective is not to cause the stateful session gone/passivated even there's
a transaction rollback in the stateless session bean. One solution I could
think of is to set the stateless session to Bean-managed and set "RequiresNew"
tx attribute to the stateless session bean methods.
Can I set tx attribute when it is a container-managed bean?
Any better suggestion? Do advise.
Thank you.
Regards,
bb
