Let's start with the jars that you are packaging as part of your WAR file. Can you post the output of jar -tf decisionserver.war similar to what you had done for the EAR. You might have to extract that war to some place outside the ear to run this command. What i am interested is the list of jar files contained in this WAR. That might give us a starting point to debug this issue. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126212#...
