HTTP Error 401 at accessing Socialcast API

Question

I receive 401 Unauthorized when trying to connect to Socialcast API (Demo). This is my code:

ClientConnectionManager connectionManager = new BasicClientConnectionManager();
    HttpClient client = new DefaultHttpClient(connectionManager);
    HttpHost proxy = new HttpHost("myproxy", myport);
    client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

    Authenticator.setDefault(new MyAuthenticator("emily@socialcast.com", "demo"));

    HttpGet httpGet = new HttpGet("https://demo.socialcast.com/api/authentication.xml".toString());
    HttpResponse httpResponse = client.execute(httpGet);
    int statusCode = httpResponse.getStatusLine().getStatusCode();
    if (statusCode == HttpStatus.SC_OK) {
        InputStream is = httpResponse.getEntity().getContent();
        System.out.println(httpResponse.toString());
    } else {
        System.out.println(httpResponse.toString());
    }

Error message:

What is wrong about it?

Answer 1

I solved it, this code works:

    System.setProperty("proxySet", "true");
    System.setProperty("proxyHost", "myproxy");
    System.setProperty("proxyPort", "myport");

    Authenticator.setDefault(new Authenticator() {
        @Override
        protected PasswordAuthentication getPasswordAuthentication() {
            System.out.printf("url=%s, host=%s, ip=%s, port=%s%n", getRequestingURL(),
                    getRequestingHost(), getRequestingSite(), getRequestingPort());

            return new PasswordAuthentication("emily@socialcast.com", "demo".toCharArray());
        }
    });

    URL url = new URL("https://demo.socialcast.com/api/users");
    System.out.println(new Scanner(url.openStream()).useDelimiter("\\Z").next());
