Look for DeliveryActive on this wiki http://www.jboss.org/community/docs/DOC-9334 Not exactly, i mean that i want it to never start unless i call start on the MDB's MBean (the one you pointed me to). In other words i want it to start as inactive, and programmatically call start/stop. I tried using DeliveryActive but it says the property doesn't exist? This seems to be somewhat of a recurring theme in the JIRA links my googling found, that's why i thought i would ask you if there was another way, or something to do about making DeliveryActive work.
