Using Hibernate 3.4 in JBoss 5.1

I've come across some problems using Hibernate 3.4 on JBoss 5.1.
Hibernate 3.4 is a JPA 1.0 implementation so it should be fine to be used in JBoss 5.1. The thing is JBoss has its own version of Hibernate, which is located at /common/lib whereas I don't want to use the version provided by JBoss. What I did is that I removed the hibernate-annotations.jar, hibernate-commons-annotations.jar, hibernate-core.jar, hibernate-entitymanager.jar, hibernate-jmx.jar and hibernate-validator.jar from that folder and put my Hibernate 3.4 jars into server/default/lib directory. I also compiled hibernate-validator.jar 3.1.0 into my war file because it seems otherwise JBoss cannot recognize where the validator is. After I have done all the above, I packaged my war file and deployed it to the deploy folder.

The server started with no issue. But when I tried to access my web application it throws an error:

It looks like it still cannot find the validator. But it is already in the war file. What have I done wrong here?

If you include (alone) the hibernate-validator.jar under the WEB-INF/lib you will have issues because Hibernate core classes are loaded from a different Classloader. What kind of error do you get when placing ALL Hibernate jars under server/<yourserver>/lib ?
