   Hallo,
   ich bin wiedereinmal am verzweifeln. Ich versuche nun schon den ganzen Tag eine SSL verbindung aufzubauen. Mit diesem beispield das ich gefunden habe geht es:

   public class SSLSocketExample {
    
       /**

        */
       public static void main(String[] args) {
           Executors.newSingleThreadExecutor().execute(new Server());
           Executors.newSingleThreadExecutor().execute(new Client());
       }
    
       static class Server implements Runnable {
           public void run() {
               try {
                   SSLServerSocket serverSocket = (SSLServerSocket) SSLServerSocketFactory
                           .getDefault().createServerSocket(5678);
                   System.out.println("Server ready..." + serverSocket);
    
                   System.out
                           .println("Supported Cipher Suites: "
                                   + Arrays
                                           .toString(((SSLServerSocketFactory) SSLServerSocketFactory
                                                   .getDefault())

                   SSLSocket socket = (SSLSocket) serverSocket.accept();
                   SSLSession sslSession = socket.getSession();
                   String cipherSuite = sslSession.getCipherSuite();
                   System.out.println(cipherSuite);
    
                   Scanner scanner = new Scanner(socket.getInputStream());
                   System.out.println("Reading...");
                   while (scanner.hasNextLine()) {
                       System.out.println("Server received: " + scanner.nextLine());
                   }
                   scanner.close();
    
                   socket.close();
    
                   serverSocket.close();
               } catch (IOException e) {
                   e.printStackTrace();
               }
           }
       }
    
       static class Client implements Runnable {
           public void run() {
               try {
    
                   SSLSocket socket = (SSLSocket) SSLSocketFactory.getDefault()
                           .createSocket("localhost", 5678);
                   PrintWriter printWriter = new PrintWriter(socket
                           .getOutputStream());
                   System.out.println("Client -> sending...");
                   for (int i = 0; i < 100; i++) {
                       String message = "Hallo: " + i;
                       System.out.println("Client sent: " + message);
                       printWriter.println(message);
                       printWriter.flush();
                       TimeUnit.SECONDS.sleep(1);
                   }
                   socket.close();
               } catch (Exception e) {
                   e.printStackTrace();
               }
           }
       }
   }

   
   
   aber bei mir geht es nicht:
   
   Client Socket erstellen
   

   SSLSocket socket = null;
   
   				do {
   					try {
   						System.out.println("connecting");
   						socket = (SSLSocket) SSLSocketFactory.getDefault()
   								.createSocket("localhost", 5678);
   
   					} catch (IOException e) {
   						e.printStackTrace();
   					}// end try
   				} while (socket == null);
   
   				connection = new Connection(socket);// klasse für
   													// String senden
   													// und empfangen
   
   				String version = Connection.send("test:-version");

   
   
   
   Connection class:
   

   private static SSLSocket socket;
   	private static OutputStream outputStream;
   	private static InputStream inputStream;
   
   	public Connection(SSLSocket socket) {
   		Connection.socket = socket;
   		try {
   			Connection.outputStream = Connection.socket.getOutputStream();
   			Connection.inputStream = Connection.socket.getInputStream();
   		} catch (IOException e) {
   			JOptionPane.showMessageDialog(
   					null,
   					"An error occured. Please call your administrator\n"
   							+ "and show this message if it occures twice.\n"
   							+ "error;init.Connection.IOException\n"
   							+ e.toString(), "Error", JOptionPane.ERROR_MESSAGE);
   			System.exit(0);
   		}
   
   	}
   
   	public static String send(String data) {
   		byte[] returnedData = null;
   		String answerBuffer = "";
   		try {
   			outputStream.write(data.getBytes());// nachricht schicken
   		} catch (Exception e) {
   			//<-----HIER TRITT DER FEHLER AUF
   			e.printStackTrace();
   			System.exit(0);
   		}

   
   
   Der Fehler ist :
   javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
   
   
   Server:
   

   try {
   			
   			serverSocket = (SSLServerSocket) SSLServerSocketFactory
                       .getDefault().createServerSocket(5678);
   		} catch (IOException e) {
   			// TODO Auto-generated catch block
   			e.printStackTrace();
   		}
   		new Thread() {
   			public void run() {
   				while (true) {
   					SSLSocket client = null;
   					System.out.println("fetching client");
   					try {
   						client =(SSLSocket) serverSocket.accept();
   						
   		                SSLSession sslSession = client.getSession();
   		                String cipherSuite = sslSession.getCipherSuite();
   		                System.out.println(cipherSuite)

   
   
   
   Falls mir jemand helfen könnte oder noch infos braucht kann er mich auch in Skype adden [den.ganzen.tag.lang] .
   
   Danke schonmal im vorraus
