title: "java.lang.UnsupportedOperationException: Not supported yet."
body: <p>What I am trying to do :</p>
  
  <p>I am trying to connect to Web Portal [that uses https]using Java.
  I have written code for supplying user credentials using Authenticator class.When I run the program I get an Exception:</p>
  
  <blockquote>
    <p>"java.lang.UnsupportedOperationException: Not supported yet"</p>
  </blockquote>
  
  <p>I have the code posted :</p>
  
  <pre><code>public class Main {
  
      public class MyAuthenticator extends Authenticator {
  
          protected PasswordAuthentication getpasswordAuthentication() {
              String username = "username";
              String password = "password";
              // Return the information
              return new PasswordAuthentication(username, password.toCharArray());
          }
  
          @Override
          public Result authenticate(HttpExchange he) {
              throw new UnsupportedOperationException("Not supported yet.");
          }
      }
  
      public static void main(String[] args) {
          // TODO code application logic here
  
  
          TrustManager[] trustClients = new TrustManager[]{
              new X509TrustManager() {
  
                  public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
                      throw new UnsupportedOperationException("Not supported yet.");
                  }
  
                  public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
  
                      throw new UnsupportedOperationException("Not supported yet.");
                  }
  
                  public X509Certificate[] getAcceptedIssuers() {
                      return null;
                      //throw new UnsupportedOperationException("Not supported yet.");
                  }
              }
          };
          try {
              SSLContext sslcontext = SSLContext.getInstance("SSL");
              sslcontext.init(null, trustClients, new java.security.SecureRandom());
              HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext.getSocketFactory());
  
          } catch (Exception e) {
              System.out.println("in 1st catch " + e);
          }
  
  
          try {
              URL url = new URL("https://someURL.server.com/fmk/jsp/ltpaLogin.jsp");
              URLConnection urlconnection = url.openConnection();
              System.out.println(urlconnection);
              System.out.print(urlconnection.getInputStream().toString());
  
  
  
  } catch (Exception e) {
              System.out.println("in 2ndcatch " + e.getMessage());
          }
      }
  }
  </code></pre>
  
  <p>the exception "java.lang.UnsupportedOperationException: Not supported yet"is raised in the 2nd Try.Is my approach correct ? if not is there any alternative to do so ?</p>
  
  <p>When I open the page in web browser I get the login page;Once I supply my credentials the web portal is displayed</p>
  
  <p>Can any one please suggest how to hit the webportal and supply my credentials and check the authentication is success or not ?
  Any sample code snippets will be really helpful
  Thanks in advance..</p>
