Title Body

I want to use GWT's RequestFactory for all client-server communication, if possible. My understanding is that you have to map /gwtServlet to RequestFactoryServlet in your web.xml , and then use @Service annotations to tell the RequestFactoryServlet how to map client-side requests to their appropriate services. Can someone provide a complete code example of this process , both on the client- and on the server-side? I'd like to send a Widget object from the client side to a WidgetProcessor service on the server-side: public class Widget { // This is a domain object (POJO). } public class WidgetProcessor { public void processWidget(Widget w) { // Inspect the Widget. If certain properties contain certain // values, place it on a queue. Else "process" the Widget // and persist it to a DB. if(w.containsSpecialValues()) QueueManager.sendToQueue(w); else { // Process widget... WidgetDAO.save(w); } } } In a non-GWT context, I would just define a WidgetProcessorServlet , map it to /processWidget , and make it look like: @Override public void doGet(HttpServletRequest request, HttpServletResponse response) { WidgetProcessor widgetProcessor = new WidgetProcessor(); widgetProcessor.processWidget(getWidgetFromRequest(request)); } How does this work in RequestFactory -land? Thanks in advance.
