gwt: making remote calls fails - sop?

I am writing some interface for users to collect data and send to a server. I went for GWT for various reasons.

Now, when I try to call my server:

String url = "http://127.0.0.1:3000/data/collection.xml";
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, URL.encode(url));

Request request = builder.sendRequest(data, new RequestCallback() {     

        public void onResponseReceived(Request request, Response response) {

              if (200 == response.getStatusCode()) {
                  result.setText("SUCCESS!");
              } else {
                  result.setText("ERROR with code: " + response.getStatusCode());

My server gets the request (a POST with some data) but I get ERROR with code: 0 (!) all the time. I guess this has to do with SOP. I read lots about this SOP but I am even more confused now. I tried to follow this tutorial but that's using a different approach (I managed to adapt it to issue GET calls only, but return objects are always null).

Can anyone point me into the right direction? thanks

You can not call any service from another server because of SOP. What you can do, you can use your original server as proxy to other servers.. I would recommend you to read this tutorial.
