	   BufferedReader entree =
	       	  new BufferedReader(new InputStreamReader(System.in));
 
       ServerSocket server = new ServerSocket(3008);	  
 
       while(true){
    	   Socket client = server.accept();
 
 
    	   BufferedReader in =
    		   new BufferedReader(new InputStreamReader(client.getInputStream()));
 
 
    	   DataOutputStream out = 
    		   new DataOutputStream(client.getOutputStream());
 
 
 
    	   if(in.ready()){
    		  String phrase = in.readLine();
    		  System.out.println("Client dit : "+phrase);
