If you packaging your war inside the ear(which also includes the ejb jars), then the remote/home interfaces need not be in the war file, since the war is *part of the ear application* which contains the necessary interfaces. However if you want the war to be a separate archive(outside the ear), then you will have to ship the remote/home interfaces of these ejbs since your war is no longer a part of the ear application - the war and the ear will act as two separate independent applications View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977602#...
