However in my app, the request is sometimes a POST with a body, sometimes it's just a GET. I can see that the example will have to be extended to handle such cases. > So now, here's the complete meat in action.

One thing I will add is stuff from Hupa (http://svn.apache.org/repos/asf/labs/hupa/src/main/java/org/apache/hupa/) that handles authentication and authorization. > It's work in progress, I have a couple things to do to generalize the > process on server side, and multiple type of objects actually doesn't > work verry well (For Batching purpose), I chose XML over json for this > very purpose. Yes, I can see that. In another application, I used XML (Perl <--> JavaScript) for just that reason. It seems you are using Eclipse? I found that the XML & DTD editors were quite helpful constructing complex structures. The DTD was also input to an XML parsing/validating editor so that users could construct source documents in XML. These documents were sent to the client to be rendered as a questionnaire. The user responses were added to the questionnaire and the resulting document POSTed to the server for transformation via XSLTPROC into HTML.

Well, you're clearly doing exactly what I've been trying to do: take lessons learned from gwt-dispatch and formulate into something that works w/ RequestBuilder. I'm just not good enough at Java to understand how to get There from Here. Thank-you very much for taking the time to post this code. I will take the time to study it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
