Spring MVC is an architecture and framework for writing Web Application. Not specific to RAD. Are you just asking for how to add the Spring plugins for Eclipse? RAD is using Eclipse underneath. For the plugins you just point your IDE to the Spring plugin update site
Well, I am a couple of weeks into setting this up and now realized that the question that I had asked is invalid....
I assumed that one could not use the springsource tutorial for RAD and also RAD might have some templates ready for setting up MVC.
I now know that the first part is wrong for sure since I am half way thru the setup. As far as the second part is concerned, I need to go over the website that you had send http://springide.org/updatesite/ to check if it would speeden up the setup of Spring MVC
