Próbuję połączyć się z usługą Google w aplikacji GAE hostowanej w chmurze GAE:

private String doPost(String URL) throws ClientProtocolException, IOException {
    // Params:
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("accountType", "HOSTED_OR_GOOGLE"));
    params.add(new BasicNameValuePair("Email", _DEFAULT_USER));
    params.add(new BasicNameValuePair("Passwd", _DEFAULT_PASS));
    params.add(new BasicNameValuePair("service", "ah"));
    // Call
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost post = new HttpPost(URL); // URL:
                                        // https://www.google.com/accounts/ClientLogin
    post.setEntity(new UrlEncodedFormEntity(p_params, HTTP.UTF_8));
    post.getParams().setBooleanParameter(
            CoreProtocolPNames.USE_EXPECT_CONTINUE, false);
    HttpResponse response = httpClient.execute(post);
    return _ProcessResponse(response); // Process...
}

Egzekucja rzuca: com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'remote_socket' or call 'Resolve()' was not found.

Jakieś pomysły? Jestem całkowicie zagubiony ...
