Sending object via Server to Client (receiving a not updated object) - server

Question

I have a simple server updating an object and sending it to a client every second. The problem is that in the client always arrive the object not updated. Can anyone help me with this?
Client.java
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.UnknownHostException;
public class Client {
public Message returnMessage;
public Client() throws UnknownHostException, IOException, ClassNotFoundException{
System.out.println("welcome client");
Socket socket = new Socket("localhost", 4444);
System.out.println("Client connected");
ObjectInputStream is = new ObjectInputStream(socket.getInputStream());
while(true){
Message me = (Message) is.readObject();
//returnMessage = (Message) is.readObject();
System.out.println("A =" + me.getA());
}
// socket.close();
}
public static void main(String[] args) throws UnknownHostException,
IOException, ClassNotFoundException {
new Client();
}
}
Server.java
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.io.*;
import java.net.*;
public class Server {
public static final int port = 4444;
private ServerSocket ss = null;
private long time = 0;
public void runServer() throws IOException, ClassNotFoundException{
ss = new ServerSocket(port);
System.out.println("Sistema pronto ad accettare la connessione");
Socket socket = ss.accept();
ObjectOutputStream os = new ObjectOutputStream(socket.getOutputStream());
//ObjectInputStream is = new ObjectInputStream(socket.getInputStream());
Message m = new Message(1, 32);
while (true){
if ((System.currentTimeMillis()-time) > 1000){
time = System.currentTimeMillis();
m.setA(m.getA()+1);
os.writeObject(m);
}
}
// socket.close();
}
public static void main(String[] args) throws ClassNotFoundException, IOException {
new Server().runServer();
}
}
Message.java
import java.io.Serializable;
public class Message implements Serializable {
private static final long serialVersionUID = -5399605122490343339L;
private int A;
private int B;
private int Result;
public Message(int firstNumber, int secondNumber ){
this.A = firstNumber;
this.B = secondNumber;
}
public int getA() {
return A;
}
public int getB() {
return B;
}
public int getResult() {
return Result;
}
public void setA(int a){
A = a;
}
public void setResult(int X) {
Result = X;
}
}
I know that in this example there is no need to send an object but I will need later on..
Thank you!
