Is there a way to listen to Transaction?

Hi,

Is there a way to listen to a transaction in JBoss? I want to listen to a transaction and upon its completion, I'd like to send an email out. How would you implement this in JBoss? Thank you very much.

Yes it is possible and it is defined in EE spec.

take a look at http://docs.oracle.com/javaee/6/api/javax/ejb/AfterCompletion.html

but it all depends on what are you doing and how.

Thanks for the reply. We have some database inserts that we want to listen to, and if it successfully posts, then we'd like to send out a jms message to down stream systems. One question is we don't use any StatefulSession bean in our system, and it looks like I have to use a StatefulSession bean. Does implementing AfterCompletion require a transaction to be started FROM a stateful session bean? Or just create a stateful session bean that listens to transactions? Thank you very much.

You can use CDI transactional observers. See the links below for details:

Thanks! This sounds like something we should look into. Thanks again.
