Can I use tar or jar command bundle the classes? IF not I may need to do it in the JBOSS applicaiton server as follow: Change the EJB3 tutorial (in the JBOSS server) so that when it creates a JAR file, it should make a directory path com/ip6networks/calling_card_registration/... and bundled all classes according this path, then copy the JAR file into tomcat/lib/ folder before running the EJB client app. Thanks Sam View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4244808#...
