I don't understand why there is a long discussion. It's clearly a bug. The WARStructure is adding WEB-INF/classes/META-INF as a metadata location, but not the META-INF folders of the nested jars. | // Create a context for this war file with WEB-INF as the location for metadata | // Some wars also might have metadata in WEB-INF/classes/META-INF, e.g. persistence.xml | context = createContext(structureContext, new String[]{"WEB-INF", "WEB-INF/classes/META-INF"}); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173378#...
