Thank you.

Answer 1

Thank you
I want to complete the client code, to load some class, from the server side.
Am i clear?
...and "unload" a class, or "finalize" all the instances of a class located remotly (server side), is it possible?
Server:
import java.net.*;
import java.io.*;
public class Serveur{
public static void main(String[] args) throws Exception{
    ServerSocket serveur = new ServerSocket(5000);
    while(true) {
      Socket socket = serveur.accept();
      BufferedReader in = new BufferedReader(
         new InputStreamReader(socket.getInputStream()));
      String cmd = in.readLine();
// parle !!!
      DataOutputStream out = new DataOutputStream( socket.getOutputStream());
      if(cmd.equals("parle")){
        out.write("bonjour\n".getBytes());
      }else{
        out.write("commande inconnue ?\n".getBytes());
      socket.close();
}Client:
import java.net.*;
import java.io.*;
public class Client{
  public static void main(String[] args) throws Exception{
    Socket socket = new Socket("localhost", 5000);
    DataOutputStream out= new DataOutputStream( socket.getOutputStream());
    out.write(args[0].getBytes());
    out.write("\n".getBytes());
    BufferedReader in = new BufferedReader(
       new InputStreamReader(socket.getInputStream()));
    System.out.println(in.readLine());
    socket.close();
}
