Hi, do you need this for a JavaEE5 JAR/EAR/WAR? If yes: do you use the Eclipse WebToolsPlatform plugin? Here, all JBoss jars are automatically added to the build path, and thus you should not have any problems. For WTP and non-JavaEE-projects: Maybe you can add a server runtime container to the build path. Hope this helps Wolfgang View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4206908#...
