As a follow-up, I tried adding Envers to a web application deployed on AS7 today, using Hibernate provided with the AS. I got some class loading problems though with dom4j. See the forum discussion:
http://community.jboss.org/message/618823#618823 I also tried creating a separate Envers module which would depend on org.hibernate, but the Hibernate doesn't seem to see the Envers Integrator. Strong Liu: isn't it something you've prepared a patch for? I don't think it was included?
