How to call Controller from View?

Does it make sense to talk of Model-View-Controller when building GWT applications?

• As far as I understand "page-based" frameworks such as Spring, Rails, etc. are "Model-View-Controller" frameworks where the next page is decided by the "Controller".  But what about for AJAX-ey style web apps where there are no page reloads, and only portions of the screen are changed at any one time?  Does it make sense to design an AJAX-ey app in an MVC kind of way? For example, I've built a GWT web application: I use about 6 classes for my "model"; about 40 classes (extending Composite) for my "view"; and one big static class that updates parts of the screen (I guess you could call this the "controller"). Is this a good way of designing a GWT app?  Or have I really missed the mark with GWT and/or MVC?

• Answer:

  Google recommends using the Model-View-Presenter pattern when developing GWT applications. You can take a look at GWTP (http://www.gwtplatform.com) that offers an open source implementation of the pattern. It also includes quite a bit of documentation and links to relevant Google IO talks.
