ok - i created http://jira.jboss.com/jira/browse/JBIDE-1367 but looking at the comments for seam2 project creations it looks like the ds.xml file in the WAR is used as the ds.xml for testing. but the resources/*ds.xml is what gets deployed. Follow the jira if you want to know the resolution of it. p.s. you always add/remove these ds.xml as you please - you just need to remember to deploy at least one other with the same datasource name.
