Question

I am using jboss5.1.x, ejb3.0

I have a transaction which goes like this:
MDB listen to JMS Queue.
MDB takes msg from JMS writing to Database.

in some of the catch clauses i throw “New EJBException(..)”, in order to have rollbacks when specific exceptions occurs.

beside of that I have configured a re-try mechanism, after 3 times the msg going to error queue.

What i wanna achive is:

when Iam having a rollback, i want to increase the current re-try number, so if some1 is observing the database, he/she can see on-line the current re-try number.

the problem is: when I do rollback, so even the “insert_number_of_retry” query is being rolled back itself, which preventing from me to add the current retry number to the database

how can I solve this?

Thanks,

ray.

You can try to execute your logging method inside a separate transaction by annotating it with @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW).
