Ich schaue auf diesen Link und versuche, Anfragen an den Server zu senden

http://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html

public class Test {
    public static void main(String[] args) throws ClientProtocolException, IOException {

        DefaultHttpClient httpClient;
        URL url = new URL("https://9.5.127.34:443");
        httpClient = getSSLHttpClient(url);
        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
                new AuthScope("https://9.5.127.34", AuthScope.ANY_PORT),
                new UsernamePasswordCredentials("root", "passw0rd"));


         httpClient.setCredentialsProvider(credsProvider);


        HttpGet httpget = new HttpGet("https://9.5.127.34/powervc/openstack/volume/v1/115e4ad38aef463e8f99991baad1f809//volumes/3627400b-cd98-46c7-a7e2-ebce587a0b05/restricted_metadata");
        HttpResponse response = httpClient.execute(httpget);
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        while ((line = rd.readLine()) != null) {

            System.out.println(line);

            }   
        }

Aber es gibt mir als Fehler

Authentication required

Bitte sag mir, was ich falsch mache. Vielen Dank im Voraus
