I could not get the Hibernate bean validation feature to work in 4.0.x. For one thing, it's in the 'enterprise' feature set, which does not work at all without extra <repository> elements which I can't have. Even when I copied it out, I still couldn't get it to work.
So I made a working feature with Apache Bval. However, the Bval project seems to be perpetually asleep, and so I can't get a problem with one of their bundles fixed. So, I'm hoping that someone has an idea about how to rehab the hibernate solution.
