[jboss-user] [Installation, Configuration & DEPLOYMENT] - How to isolate my class from the lib jar

Problem: I need to use an old version of Hibernate3.jar but in JBoss 4.0.4 there is a new version that I do not want Solution 1: delete Hibernate3.jar from \lib folder. Works, but it's so ugly. I've tried to add in my jboss-app.xml: <loader-repository> jboss.test:loader=my.ear <loader-repository-config> java2ParentDelegation=true </loader-repository-config> </loader-repository> But, nothing changes, I see that \lib jar are seen before mine. (I've made a test class with same name but different behaviour in the \lib folder and in my ear folders and I see the \lib one) If I write java2ParentDelegation=true ... JBoss do not start at all, because during deploy of my.ear I need, of course, some of the \lib jars of JBoss. My .ear is somehow "strange" because I do have many subfolders and the path of them is written in the jboss-service.xml of the .sar (inside .ear), using the classpath tag. Thanks for any suggestion.
