Running on JBoss 4.2.3 with some EJB2 and some EJB3 MDBs spread amongst various jar/sar files. I had found that I could use the invoker which pertained to an MDB queue to stop/start message deliver and tested it using invocation calls through twiddle. This works great for EJB2 deployments. For my EJB3 MDBs, there isn't an invoker for the queue so what's the difference? Does JBossMQ queue deployment work differently between the two versions of EJB? Looking at the JMX console, I can see that there are queues for all my MDBs, regardless of the EJB version. To get more of an idea what I did get to work with the EJB2 MDBs check out... http://www.vijaykandy.com/archives/9 Any help is greatly appreciated!! p.s. If this is off topic, kindly point me in the right direction. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249713#...
