Hi Jim, it seems your app is not bundled according to the JavaEE spec. It should be (taken your sample): Shop.ear | |---META-INF\application.xml (this file is not required) | |---Shop.jar | |--META-INF\manifest.mf | |--META-INF\ejb-jar.xml (optional) | |--EJB classes and interfaces | |---Shop.war | |--META-INF\manifest.mf | |--WEB-INF\web.xml | |--WEB-INF\lib\yourlibraries.jar | |--WEB-INF\classes\.... | |--web\some.jsp The "Shop.war" must not contain any classes which are already contained in "Shop.jar". Seems the classes in your WAR are in the wrong location. Hope this helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4236387#...
