In JBossAS 5.0, JBoss Messaging has replaced JBossMQ. The new configuration file for the default destinations is server/xxx/deploy/messaging/destinations-service.xml. Note that this file contains only the required default queues and not the
testing queues and topics that were in the old JBossMQ destinations file; but you can download JBoss Messaging and get the set of testing queues from there,
There is no change to the datasource configuration files - the example *-ds.xml files are still located in docs/examples/jca. (There is no mcs-oracle-ds.xml file in the server/xxx/deploy directory in the 4.0.4 distribution - if you have one there you must have placed it there.)
