Pro and Cons to create a REST architechture using [SPRING MVC] or [GWT + MVP] (and using spring ROO)?

Question

I am asking this question because, I see that Roo include SPRING MVC and GWT...but
- GWT (on its website) shows an example of a MVP pattern but I think it is not comparable with the SPRING MVC framework (indeed Spring MVC has more features. I have never used it...but I read that it helps a lot to do website, and easily lets have a REST architecture (how to do as easily a REST architecture with GWT and a MVP plateform ?)...

Can you help me to choose between these technologies (taking care that I want to develop my app on GAE, and I will also want Mobile phone version) ?

I suggest you not to use GWT with Roo, its GWT support extremely buggy at the moment. (Saying this as a big fan of Roo)

Also, REST is architectural style which embraces HTTP as an application protocol, not only as a transport protocol, meanwhile GWT is a framework, or rather a toolset for creating rich web application which use JavaScript as a frontend, one has basically nothing to do with the other. You can however use Spring MVC to build RESTful applications:
