Hi Wolfgang, yes I had to add "Shop.war", because the helper classes which are called from the index.jsp are located unter web/ i.e. the war file contains 2 directories META-INF/ and web/ and under web these helper classes are located. Surely, the war file is packed in an EAR file named Shop.ear which contains it's own META-INF subdirectory, namely META-INF/MANIFEST.MF and META-INF/application.xml and the above mentioned war file Shop.war as well as a jar file Shop.jar where the entities and session beans are packed. Best wishes, Jim WebShop.jar WebShop.war View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4236369#...
