title: Java SSL code throwing NoSuchAlgorithException
body: <p>I'm working on a project that I want to add SSL to, so I created a simple client/server test implementation to see if it worked and I get a NoSuchAlgorithmException.  The following is my server code which is throwing the exception:</p>
  
  <pre><code>import java.io.*;
  import java.net.*;

  import java.security.KeyStore;
  import java.security.KeyStoreException;

  import java.security.cert.CertificateException;

  public class SslServer
  {
      private static final int PORT = 5555;
  
      public static void main(String[] args)
      {
          SecureRandom sr = new SecureRandom();
          sr.nextInt();
  
          try {
              //client.public is the keystore file that holds the client's public key (created with keytool)
              KeyStore clientKeyStore = KeyStore.getInstance("JKS");
              clientKeyStore.load(new FileInputStream("client.public"), "clientpublicpw".toCharArray());
  
              //server.private is the key pair for the server (created with keytool)
              KeyStore serverKeyStore = KeyStore.getInstance("JKS");
              clientKeyStore.load(new FileInputStream("server.private"), "serverprivatepw".toCharArray());
  
              TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
              tmf.init(clientKeyStore);
  
              //This next line is where the exception occurs
              KeyManagerFactory kmf = KeyManagerFactory.getInstance("TLS");
              kmf.init(serverKeyStore, "serverprivatepw".toCharArray());
  
              SSLContext sslContext = SSLContext.getInstance("TLS");
              sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), sr);
  
              SSLServerSocketFactory sf = sslContext.getServerSocketFactory();
              SSLServerSocket ss = (SSLServerSocket)sf.createServerSocket(SslServer.PORT);
              ss.setNeedClientAuth(true);
  
              BufferedReader in = new BufferedReader(new InputStreamReader(ss.accept().getInputStream()));
  
              String line = null;
              while((line = in.readLine()) != null)
              {
                  System.out.println(line);
              }
              in.close();
              ss.close();
          } catch (IOException e) {
              e.printStackTrace();
          } catch (NoSuchAlgorithmException e) {
              e.printStackTrace();
          } catch (CertificateException e) {

          } catch (KeyManagementException e) {
              e.printStackTrace();
          }
      }
  
  }

  <p>The stacktrace I get is:</p>
  
  <pre><code>java.security.NoSuchAlgorithmException: TLS KeyManagerFactory not available
      at sun.security.jca.GetInstance.getInstance(Unknown Source)
      at javax.net.ssl.KeyManagerFactory.getInstance(Unknown Source)
      at SslServer.main(SslServer.java:32)
  </code></pre>
  
  <p>I tried replacing "TLS" with "SSL" and I still got the same exception.  That Didn't make sense to me.  How can TLS and SSL not be supported?  This is my first time trying to implement SSL and it seems difficult to find good resources about this with code examples that are well explained.  Can anyone tell me why I am getting this exception or point out something wrong with my code?</p>
