The one that you posted is the jboss-app.xml. Based on the EAR hierarchy you posted, the Application.jar is at the root of your EAR. This won't be added to the classpath, unless you have an module entry for this jar, in the application.xml or you move it to a folder named lib at the root of the EAR. Like this: | Application.ear | | | |--- lib | | | | | |--- Application.jar | | | | | |--- Application.war View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4165806#...
