JSR 303 and JVM Web Framework Support

Emmanuel Bernard recently sent an email to the JSR 303 Experts Group about the next revision of the Bean Validation JSR (303). Rather than sending the proposed changes privately, he blogged about them. I left a comment with what I'd like to see:

+1 for Client-side validation. I'd love to see an API that web frameworks can hook into to add "required" to their tags for HTML5. Or some service that can be registered so the client can make Ajax requests to an API to see if an object is valid.

Emmanuel replied that most of the necessary API already exists for this, but frameworks have been slow to adopt it.

Hi Matt,

The sad thing is that the API is present on the Bean Validation side but presentation frameworks are slow to adopt it and use it :(

RichFaces 4 now has support for it but I wished more presentation frameworks had worked on the integration. If you can convince a few people or have access to a few people, feel free to send them by me :)

The integration API is described here. Let me know if you think some parts are missing or should be improved. We should definitely do some more buzz around it.

In the interest of generating more buzz around it, I decided to do some research and see what JVM Frameworks support JSR 303. Here's what I've come up with so far (in no particular order):

Struts 2 has an open issue, but doesn't seem to support JSR 303. Since I did a quick-n-dirty google search for most of these, I'm not sure if they support client-side JavaScript or HTML5's required. If you know of other JVM-based web frameworks that support JSR 303, please let me know in the comments.
