btw, before i forget , what is the difference between the isoalted parameter and the one in the jboss-app.xml file (java2ParentDelegation=false)

It just applies at different levels. The isolated flag in the ear-deployer.xml sets this at the server instance level which means that all applications deployed in that server instance will follow that setting.

Whereas using the jboss-app.xml is per application setting which means that an application A might use isolated deployments whereas some other application on the same server instance may not.

that's what i thought at first, but when i placed the one in jboss-app i saw additional required jars (NoClassDefFound) for rife-contnations what that is, so i figured it might be something else.

once i removed all jars (and there half of them) can i be sure i would no longer have differences in was ?

also dont' know if this is the right place can you tell me what's the diiffence between javaasists and cglib from hibernate's point of view? (meaning if changing one, effects hibernate in functionality level.

When configuring classloading, you should package the right "set" of jars. So if you are trying to package your own version of hibernate, you should be sure that you package the correct versions of hibernate "dependencies" too. Not doing so can lead to some classes being picked up from the server's library and those classes may be of a different version. All this can lead to classloading issues like NoClassDefFoundError.

I assume, was = WebSphere Application Server? Ideally you shouldn't have any issues, but it again depends on how you configure classloading there. Remember, jboss-app.xml will be of no use there. You will have to go through their configuration guide to see how classloading isolation can be achieved.

Hibernate user forum would be a better place https://forum.hibernate.org/viewforum.php?f=1
