Lisa, In addition to Thomas' link there is another good document to start with: http://code.google.com/webtoolkit/doc/latest/DevGuideRequestFactory.html
It describes well how RF bridges client and server sides. The Roo- generated code will become easier to understand after reading this article. Even though the document describes to 2.1.0, 2.1.1 additions (ServiceLocator) will become easier to grasp.
