I'm trying to implement a calculator web service on GAE using Java Restlets... it works perfectly fine on localhost but when I upload my project to the Google App Engine everytime I try the web service link it says the link is broken. Here's the code I used:

public Restlet createInboundRoot() { // Create a router Restlet that routes each call to a // new instance of HelloWorldResource. Router router = new Router(getContext());

    Restlet restlet = new Restlet() {  
        public void handle(Request request, Response response) {  
            // Print the requested URI path  
            String parameters = request.getResourceRef().getRemainingPart();
            String message;
            if(parameters.charAt(0)=='?'){
                message = "" + Calculator.calculate(parameters.substring(1));
            } else {
                message = "";
            }
            response.setEntity(message, MediaType.TEXT_PLAIN);  
        }  
    };  

    // Defines only one route
    router.attachDefault(restlet);

    return router;
}

The Application it's on is mapped to the /calcservice but as I said when I upload to GAE it comes back with a broken link error. I'm developing on Eclipse 3.4 and I'm wondering if there are any parameters I have to change to include the Restlet classes.
