Tried a few things on JBoss-5 CR1 and JBoss-4.2.2 GA. There are changes in the way the deployers are working in CR1. Earlier in JBoss-4.2.2 there was a jboss-web.deployer in the deploy folder. Only the ROOT.war which was inside this jboss-web.deployer would be first deployed, then the datasources (present in the deploy folder) and then the war files in the deploy folder. In CR1, the deployers have been moved to %JBOSS_HOME%\server\< serverName>\deployers folder. And the war files in the deploy folder are always deployed first and then the datasources. So yes, the ordering has changed and hence the issue that you are seeing. I will have to look into the documentation or the deployers folder to see if the order of the deployers can be changed to deploy the datasources first.
