At this time the XXX-persistence-service.xml files are not provided with JBossAS - you have to get them from the JBoss Messaging download. (I hope that this oversight is corrected in the CR1 release or definitely by GA. Hint. Hint.) 5.0.beta4 uses JBoss Messaging 1.4.1.Beta1. Download that exact version of JBoss Messaging binary, and the XXX-persistence-service.xml files are located in exemples/config. (Note that is you download the wrong version, it will not work!)
