Using RemoteServiceServlet in a mobile application with phonegap

[albergebin]

I am trying to use RemoteServiceServlet within a mobile app. (GWT 2.7.0)

Server Side :
public class MyRpcServiceImpl extends RemoteServiceServlet implements MyRpcService{

private static final long serialVersionUID = 1L;

@Override
public String getString(String widgetRequest)
throws IllegalArgumentException {
return "String from server";
}

}

App Side :
public void onModuleLoad() {
myRpcServiceAsync.getString("", new AsyncCallback<String>(){

@Override
public void onFailure(Throwable caught) {
SC.warn(caught.getMessage() + "\n" + caught.toString());
}

@Override
public void onSuccess(String result) {
SC.say(result);
}

});
....

Works fine when I test under eclipse/Jetty.

When I deploy to PhoneGap (developper) and test, I receive the message from SC.warn...

WARNING
0
com.google.gwt.user.client.rpc.StatusCodeException
0

It looks like node.js is not able to handle my servlet.
I cannot see any error message in phonegap log.

Could you help ?
Any other way to use Jetty/Tomcat instead of node.js within Phonegap.

I would save redevelopping backend services if I could make it work.

Thanks for help

Hello,

I have a missing link
1. smartgwt.mobile project is deployed by Eclipse to the cloud where GAE generate javascript + html pages for browsers
2. when I developed phonegap projects I put 100% javascript in the package for app generators, all locally.
I never used localy the java to javascript generator. How did you start it ?

Regarding your problem I do not understand the server part. Shouldn't be something like this ?

public class CountriesDataProviderServlet extends HttpServlet{
    @Override
    protected void doPost( HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
                .... prepare data for the client and send it ....    
    }
     .... doGet ....
}

There are some examples in the showcase
