Hi all, You've probably seen this, but in case you haven't, I responded to David Van Couvering's blog (http://weblogs.java.net/blog/davidvc/archive/2007/04/jpa_and_rollbac.html) where he cites problems with JPA's rollback behavior. I also responded on the TSS.com thread (http://www.theserverside.com/news/thread.tss?thread_id=45173).
