Guess 1: A -ds.xml is deployed before an ear so it wouldn't be suprising if it couldn't find the classes - see Vicky's comment Guess 2: If the ear is scoped and the -ds.xml is outside the ear then you also have to tell the -ds.xml what classloader repository to use. If you don't it will use the default repository which won't know about any classes from the ear. This is the same as for a -service.xml that depends upon a scoped ear: http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration e.g. | <connection-factories> | <loader-repository>jboss.j2ee:service=EARDeployment,url=myapp.ear</loader-repository> | | <etc/> | Or whatever you called the scoped repository in jboss-app.xml View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127861#...
