I have a .EAR with about 15 wars. When the .EAR is deployed, I found out from server.log, any jars in the webapp.ear/lib are copied "number of .war" times by the jboss main deployer. Say for example, I have jdom.jar in the .ear, and it's copied 15 times, for each war within the ear..... is there anyway to resolve this? Is copying the jars the only way to share libraries between .wars within a .ear??
