I try to retrieve XML data from an external server and to display informations on my GWT application.

The problem is that I don't succeed to display the xml informations.

my java code :

    protected void retrieveXmlDataTop(final VerticalPanel c) {

        url = "http://ift.tt/1GwDnKJ";

        RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,URL.encode(url));

        try
        {
            builder.sendRequest(null, new RequestCallback() {

                @Override
                public void onError(Request request, Throwable exception) {
                    // Couldn't connect to server (could be timeout, SOP
                    // violation, etc.)
                    Window.alert("Couldn't retrieve XML");

                }

                @Override
                public void onResponseReceived(Request request, Response response) {

                    if (200 == response.getStatusCode())
                    {
                        // Process the response in response.getText()
                        parseMessage(c , response.getText());
                    }
                    else
                    {
                        // Handle the error. Can get the status text from
                        // response.getStatusText()
                        //Window.alert("Error: " + response.getStatusText());
                        Label error = new Label("Error");
                        c.add(error);
                    }
                }


            });
        }
        catch (RequestException e)
        {
            // Couldn't connect to server
            Window.alert("Couldn't connect to server to retrieve the XML: \n");
        }
    }

    private void parseMessage(final VerticalPanel c, String messageXml)
    {
        try
        {
            // parse the XML document into a DOM
            Document messageDom = XMLParser.parse(messageXml);

            String tag1Value = messageDom.getElementsByTagName("ranking").item(0)
                    .getFirstChild().getNodeValue();
            String tag2Value = messageDom.getElementsByTagName("title").item(0)
                    .getFirstChild().getNodeValue();

            //Window.alert("Ranking Value: " + tag1Value + "\n" + "Title Value: " + tag2Value);
            Label result = new Label("Ranking Value: " + tag1Value + "\n" + "Title Value: " + tag2Value);
            c.add(result);

        }
        catch (DOMException e)
        {
            Window.alert("Could not parse XML document.");
        }
    }

And my xml page :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<movies>
 <movie>
  <idIMDB>tt0111161</idIMDB>
   <ranking>1</ranking>
    <rating>9.2</rating>
     <title>The Shawshank Redemption</title>
      <urlPoster>http://ift.tt/1GwDnKL;
       <year>1994</year>
 </movie>
</movies>

I obtain always the message "Error".

Thank you for your help
