Threads et connection

Voilà mon problême : je voudrais créer un prog' en java qui lance un thread qui se connecte à un hôte puis l'endormir et le réactiver quand l'utilisateur veut envoier une demande, recevoire la réponse puis se réendormir et ainsi de suite. Voici mon prog', il est un peu long mais bon... :

import java.io.*;
import java.net.*;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class TrivialApplication
{
public static void main(String[] args)
{
OmenFrame frame = new OmenFrame();
frame.show();
}
}
public class OmenFrame extends Frame implements ActionListener
{
TextField address;
Button connect;
TextArea message;
TextArea response;
public OmenFrame()
{
setTitle("The Omen Connecter");
setSize(300, 400);
setLocation(50, 50);
setResizable(false);
setLayout(new FlowLayout());

s = new OmenThread("127.0.0.1", 21);

address = new TextField("", 32);
connect = new Button("Envoier");
message = new TextArea(8, 40);
response = new TextArea(16, 40);

add(address);
add(connect);
add(message);
add(response);

setBackground(Color.gray);
setForeground(Color.black);
address.setBackground(Color.white);
connect.setBackground(Color.white);
message.setBackground(Color.white);
response.setBackground(Color.white);
repaint();

Font font = new Font("Monaco", Font.PLAIN, 10);
address.setFont(font);
connect.setFont(font);
message.setFont(font);
response.setFont(font);

response.setEditable(false);

connect.addActionListener(this);
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
dispose();
System.exit(0);
}
});
}
public void actionPerformed(ActionEvent e)
{
if(!s.getParam().equals(address.getText())) s = new OmenThread(address.getText().substring(0, address.getText().indexOf(":")), toNumbers(address.getText().substring(address.getText().indexOf(":") + 1, address.getText().length())));
else
{
s.WakeUp();
response.append(s.Write(message.getText()));
response.append(s.Read());
s.Sleep();
}
}
OmenThread s;
public int toNumbers(String line)
{
int num = 0;
boolean more = true;
int i = 1;
while(i < 65535)
{
if(line.equals("" + i + ""))
{
num = i;
break;
}
else i++;
}
return num;
}
}
public class OmenThread extends Thread
{
String host;
int port;
Socket s;
boolean sleepy;
public OmenThread(String ihost, int iport)
{
host = ihost;
port = iport;
}
public void run()
{
try
{
s = new Socket(host, port);
sleepy = true;
while(true) Sleeping();
}
catch(IOException i)
{
}
catch(InterruptedException i)
{
}
}
public String Read()
{
String response = "";
try
{
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
String line;
while((line = in.readLine()) != null)
{
response += "" + line + "\r";
}
}
catch(IOException i)
{
}
return response;
}
public String Write(String message)
{
String response = "";
System.out.println(message);
try
{
BufferedReader text = new BufferedReader(new StringReader(message));
PrintWriter out = new PrintWriter(s.getOutputStream());
String mes;
while((mes = text.readLine()) != null)
{
out.println(mes);
out.flush();
response += "" + mes + "\r";
}
}
catch(IOException i)
{
}
return response;
}
public synchronized void Sleeping() throws InterruptedException
{
while(sleepy) s.wait();
}
public void Sleep()
{
sleepy = true;
}
public synchronized void WakeUp()
{
sleepy = false;
s.notify();
}
public String getParam()
{
return host + ":" + port;
}
}

Vous seriez vraiment sympa de m'expliquer pourquoi cela ne marche pas.

PS: j'ajouterait que je l'ai fait de mes mains donc merci de ne pas le réutiliser.
