Hi

Using JBoss 4.0.2 (Sun or JRockit JVM) on Windows XP.

I have an MDB that in some cases takes a number of minutes to process its 
message. There can be a number of these working on messages concurrently. In 
development, I have logging during processing so I can see % complete.

I just found out that if I try to either redeploy my EAR, or if I try to 
shutdown JBoss on the console (CTRL-C), any of these MDBs that are running will 
continue running until they complete--and the shutdown process will simply wait 
for them. No call to ejbRemove() is made, and there don't seem to be any other 
callbacks I can register.

I've only see one posting on this forum related to this, and there was one 
proposal--using a sort of Singleton in a separate queue to act as a semaphore 
if the server was shutting down. Doesn't sound like a very clean (or reliable) 
solution.

Any ideas on the correct way to trap a server shutdown and stop my MDB 
processing cleanly? The message can stay in the queue, it can be retried 
later--the issue is just that I can't stop this long-running processing.

TIA
Patrick
