After authentication from google servers for google docs, I do a simple getResponse, but I get a 400 Bad Request. I can’t understand where am I going wrong. The sample code is, below

  private void executeRefreshAlbums() {
        HttpRequest request = transport.buildGetRequest();
        request.url = GoogleDocsUrl.forDefaultPrivateFull();
        System.out.println("URL = "+request.url);
        try {
            HttpResponse response = request.execute();
            System.out.println("Response = "+response.getContent());

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

  }

The sysout prints the correct url as

03-12 17:36:59.573: INFO/System.out(451): URL = https://docs.google.com/feeds/default/private/full

But When I do this, I get 

03-12 17:43:41.360: WARN/System.err(3958): com.google.api.client.http.HttpResponseException: 400 Bad Request

    At the other thread user @Merlin provided the solution which solved similar issue. His solution was to specify the API version number 3.0 in the request as stated in the “Google Documents List Data API” document:

    Important: If you make a request to the API that uses a feature only
    available in version 3, but forget to set the version, you will most
    likely receive a 400 Bad Request response. Since the URL structure is
    different between versions 2 and 3, this is a common mistake made by
    new users of the API.

    To specify a version number, use the
    GData-Version HTTP header. The value of this header must be 3.0. The
    decimal and the zero are required.

     GData-Version: 3.0

    Alternatively,
    you can specify v=3 as a query parameter in the URL. This is often
    needed when working behind a firewall that strips HTTP headers, or
    from some JavaScript requests. Use of the HTTP header is recommended
    when possible.
