This is not ready for a full review yet. But I want to get some early feed back.
I am using using the HibernateValidator during the compile. To do this I created user/src/org/hibernate/validator/HibernateValidator.gwt.xml and associated files. It might be better if this actually lived in the hibernate source. It should be easy to use a different Validator implementation like Apache BVAL The hibernate XxxValidator's sources must be available for GWT to compile them. I override some of them as needed to either use the GWT version, or always fail if they are actually called from the client. How shall we package the Hibernate Validation jars and Module? http://gwt-code-reviews.appspot.com/863801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
