Where are the RESTful frameworks for Java?

I've been doing some research into RESTful web services recently. We may be going down this route, so I've been tasked with giving a presentation to the development team on the topic. As part of this, I checked out what Java frameworks are available to simplify the process. The answer seems to be - not many. I've found Gomba and sqlREST which both turn data exposed via JDBC into RESTful web services. But that's it.

I'd expect that there'd be something along the lines of Hibernate that would allow you to declare resources, their URIs and how the different operations (GET, POST etc) map to method calls in Java.

Maybe I'm not looking hard enough, or I've overlooked some reason why such a framework isn't worth writing?
