GWT 2.1 has introduced new framework: RequestFactory for working with server object (entity or not entity) more easily.
According to Google, GWT-RequestFactory is data-oriented and GWT-RPC is service-oriented. In my opinion, GWT-RequestFactory works like lightweight remoting-object mechanism with 2 hands; in otherwise, traditional GWT-RPC works like remoting-method mechanism.
The 2 hands of GWT-RequestFactory are EntityProxy and RequestContext:
-EntityProxy: remotes getters/setters of server object
-RequestContext: remotes methods of server object
With RequestFactory, developers can build their app more data-oriented and more object-oriented. Below is an example for building a simple app by using GWT-RequestFactory in MVP framework.
