Socket SSLServer Probleme

[LongBit]

Hallo Forum,
ich habe mich hier angemeldet, da ich mir schon seit Wochen den Kopf über eine SSLSocket verbindung den Kopf zerbreche...

package test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

import javax.net.ServerSocketFactory;
import javax.net.ssl.SSLServerSocketFactory;

public class SSLThread extends Thread {
   
    public ServerSocket serversocket;
    public Boolean Alive = true;
   
    @Override
    public void run() {
        System.out.println("Server started!");
        System.setProperty("javax.net.ssl.keyStore", "/key.jks");
        System.setProperty("javax.net.ssl.keyStorePassword", "pwd2015");
        while(Alive) {
            try {
                Socket s = serversocket.accept();
                BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
                String msg = in.readLine();
                System.out.println(msg);
            } catch (IOException e){
                e.printStackTrace();
            }
        }
        System.out.println("Server stopped!");
    }
   
    public SSLThread(int Port) {
        try {
            ServerSocketFactory factory =  SSLServerSocketFactory.getDefault();
            this.serversocket = factory.createServerSocket(Port);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
   
    public void kill() {
        this.Alive = false;
    }
}

Dieser Thread wird beim starten des Servers ausgeführt

Mein Client habe ich folgendermaßen programmiert:

import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.UnknownHostException;

import javax.net.SocketFactory;
import javax.net.ssl.SSLServerSocket;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

public class Test extends JFrame {

    private JPanel contentPane;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    Test frame = new Test();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
    /**
     * Create the frame.
     */
    public Test() {
        System.setProperty("javax.net.ssl.keyStore", "C:/Temp/key.jks");
        System.setProperty("javax.net.ssl.keyStorePassword", "pwd2015");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);
       
       
        JButton btnSsl = new JButton("SSl");
        btnSsl.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                try {
                    SocketFactory ssf = SSLSocketFactory.getDefault();
                    SSLSocket s = (SSLSocket) ssf.createSocket("172.30.1.102", 13000);
                    s.startHandshake();
                    PrintWriter pw = new PrintWriter(s.getOutputStream());
                    pw.println("Hello World");
                    s.close();
                } catch (UnknownHostException e1) {
                    e1.printStackTrace();
                } catch (IOException e1) {
                    e1.printStackTrace();
                }
            }
        });
        btnSsl.setBounds(150, 125, 89, 23);
        contentPane.add(btnSsl);
    }
}

Ich bekomme dann diesen Fehler:

Wo kann der Fehler liegen?

Danke an alle die es sich angeschaut haben, auch wenn sie zu keiner Lösung gekommen sind!

Mit Freundlichen Grüßen
