I'm developing a GWT application with a Spring backend that uses JSR 303 validation. The application can go offline and use the browser HTML5/Gears database instead.

What is the best way to implement the client validation? So far I have found gwt-validation framework (http://code.google.com/p/gwt-validation/) but it seems it is no longer active.

Thanks!

UPDATE:

There is a new GWT official project to support JSR 303 Bean Validation (link here). IMO this is the way to go once the project is mature enough.
