Response Status 401 while trying to retrieve project areas from RM Catalog!!!

Hi

I am trying to retrieve project areas from the RM catalog through OSLC URL https://localhost:9443/rm/discovery/RMCatalog through the following java code

private String fetchProjectXML(String login, String password,
            String catalogURI) {

        String server = "https://localhost:9443/rm";
        String mediatype = "application/rdf+xml";
        String node = null;
        try {
            // Setup the HttClient
            HttpClient httpclient = new DefaultHttpClient();
            HttpUtils.setupLazySSLSupport(httpclient);
            HttpGet documentGet = new HttpGet(catalogURI);
            System.out.println("document get :: "+documentGet.toString());
           
            documentGet.addHeader("Accept", mediatype);
            documentGet.addHeader("OSLC-Core-Version", "2.0");
            HttpResponse response = HttpUtils.sendGetForSecureDocument(server,
                    documentGet, login, password, httpclient);
           
            System.out.println("Response"+response.toString());

            System.out.println("Response Status Code"+response.getStatusLine().getStatusCode());
           
            if (response.getStatusLine().getStatusCode() == 200) {
                HttpEntity entity = response.getEntity();
                String responseString = EntityUtils.toString(entity, "UTF-8");
                 System.out.println("response=="+responseString);
           
                node = responseString;

                HttpUtils.printResponseHeaders(response);

            }
 
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InvalidCredentialsException e) {
            e.printStackTrace();
        } finally {
            // Shutdown the HTTP connection
            // httpclient.getConnectionManager().shutdown();
        }
        return node;
    }

public static HttpResponse sendGetForSecureDocument(String serverURI, HttpGet request, String login, String password, HttpClient httpClient)
            throws IOException, InvalidCredentialsException {
        DEBUG=true;
        // Step (1): Request the protected resource
        if (DEBUG) System.out.println(">> GET(1) "+request.getURI());
        HttpResponse documentResponse = httpClient.execute(request);
        System.out.println("Reponse status"+documentResponse.getStatusLine().getStatusCode());
        if (DEBUG) {
            System.out.println(">> Response Headers:");
            HttpUtils.printResponseHeaders(documentResponse);
        }
       
        if (documentResponse.getStatusLine().getStatusCode() == 200) {
            Header header = documentResponse.getFirstHeader(AUTHREQUIRED);
            if ((header!=null) && ("authrequired".equals(header.getValue()))) {
                documentResponse.getEntity().consumeContent();
                // The server requires an authentication: Create the login form
                HttpPost formPost = new HttpPost(serverURI+"/j_security_check");
                List<NameValuePair> nvps = new ArrayList<NameValuePair>();
                nvps.add(new BasicNameValuePair("j_username", login));
                nvps.add(new BasicNameValuePair("j_password", password));
                formPost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

                //Step (2): The client submits the login form
                if (DEBUG) System.out.println(">> POST "+formPost.getURI());               
                HttpResponse formResponse = httpClient.execute(formPost);
                if (DEBUG) HttpUtils.printResponseHeaders(formResponse);
               
            header = formResponse.getFirstHeader(AUTHREQUIRED);
                if ((header!=null) && ("authfailed".equals(header.getValue()))) {
                    // The login failed
                    throw new InvalidCredentialsException("Authentication failed");
                } else {
                    formResponse.getEntity().consumeContent();
                    // The login succeed
                    // Step (3): Request again the protected resource
                    if (DEBUG) System.out.println(">> GET(2) "+request.getURI());
                    HttpGet documentGet2;
                    try {
                        documentGet2 = (HttpGet)(request.clone());
                        return httpClient.execute(documentGet2);
                    } catch (CloneNotSupportedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
        }
    }
        return  documentResponse;
    }

I am getting a 401 response status for the above code. I understand that this error occurs if the user is unauthorized, but care is taken that the user has JazzAdmin Repository permission as well as necessary license.

It would be very helpful if some one could address this issue.

Thanks in advance.
