[jboss-user] [Messaging, JMS & JBossMQ] - onMessage:catching all Throwable but message redelivered

[dkane]

Dear colleagues, 

My onMessage method of MDB calls session bean that performs database operations. 
Some database errors (constraint violation, etc.) are normal cases and should not cause message redelivery. So I wrapped the whole onMessage code into the try..catch . But even if I catch all Exceptions and even Throwables, message is being redelivered. 
When no error happens, it is not being redelivered. 
How to avoid this unwanted redelivery ? 

Thank you.
