I assume this plan involves running Rhino as the server side Javascript engine? I don't think that's a good idea. Validator shouldn't have to start up a Javascript engine on the server just to do some validations. Javascript is a client side validation tool that's a convenience to users. The real benefit from Validator is the server side checks it performs which should remain in Java.
