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:
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.
