So I am deploying a war. Off the root of the war I have a path say myApp.war\somedir\ inside that directory resides a jar file. Inside that jar file is a lib directory, so we would have myApp.war\somedir\myJar.jar\lib\otherJar.jar. The classes inside the otherJar.jar are not being loaded, so the classes inside the myJar.jar are throwing NoClassDefFoundErrors for classes that are in the otherJar.jar Are these classes supposed to be loaded? If so, why would I get these errors. It works in AS 4.x but not in AS 5 Beta 2. Thanks Mark View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043993#...
