  | I mean really dude, you are treating this RAR as the 'holy grail' of Timer integration when all it really does, stupidly might I add,  is register an MDB listener for a single Quartz job. So I guess if I am intersted in listening  to say...3 jobs...do I need 3 endpoints? How about 10?  What if I never deploy an endpoint at all...do I still want the Scheduler up and running....doing nothing but showing up in a ThreadDump.

  | At the very least, I think for 4.0.5, the RAR should go in the docs directory giving the client a choice if they want to deploy the adapter or not.

You are not listening to me.  I'm not looking for this to be the "holy grail" for Timers.  I just want it available as an optional Quartz deployment mechanism and integration with MDB.  That RAR *IS NOT*, I repeat *IS NOT* the basis for any Timer integration.

All this RAR is a simpler User API for using Quartz so that a quartz job can post to an MDB.  Nothing more.

  |      </activation-spec>
  |    </message-driven>
  | </ejb-jar>

The idea of this RAR is that it is portable to *ANY Java EE Vendor*.  Yes, it is bare bones, but it works.  And, it is documented somewhat as a EJB3 tutorial.

To be honest, since all you guys have been assholes about this crap, then do whatever the hell you want.  I seriously don't care anymore.
