Problem with updating the jTextArea - swing

Question

I am writing a RMI chat program. In my program I am able to receive and send messages, but i am not able to display it in the TextArea. I am not sure what is the error. I tried using Event Dispatch method also. It doesn't help.
public class client extends javax.swing.JFrame implements inter {
public client() {
initComponents();
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try {
final inter i = (inter) Naming.lookup("rmi://localhost:1111/client1");
final String msg = jTextField1.getText();
if (msg.length() > 0) {
jTextArea1.append("Me :" + msg);
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
try {
i.rcvMsg("Client 1 : " + msg);
} catch (RemoteException ex) {
}
}
});
}
} catch (RemoteException ex) {
} catch (NotBoundException ex) {
} catch (MalformedURLException ex) {
}
}
public void rcvMsg(String msg) {
final String s = msg;
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
System.out.println("server called");
System.out.println(s);
jTextArea1.append(s);
System.out.println("client msg" + java.awt.EventQueue.isDispatchThread());
jTextArea1.update(jTextArea1.getGraphics());
}
});
}
public static void main(String args[]) {
try {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new client().setVisible(true);
}
});
client c2 = new client();
inter stub = (inter) UnicastRemoteObject.exportObject(c2, 0);
Registry registry = LocateRegistry.createRegistry(1113);
registry.bind("client2", stub);
} catch (AlreadyBoundException ex) {
} catch (AccessException ex) {
} catch (RemoteException ex) {
}
}
}
Please help...

Answer 1

just sharing some information using getGraphics() is not appreciated and can cause problems,
jTextArea1.update(jTextArea1.getGraphics());
and i have also created chat application with RMI:
Pass by reference problem in RMI? there is also client written over there, may be that would be useful for you.

Answer 2

In main after creating c2, call c2.setVisible(true);
The code in rcvMsg is being called on the c2 instance of client. Since the c2 instance is never made visible, you see no change.
You probably want a client to connect to a server, not directly to another client. The client-to-client will work for 2 endpoints. But what happens if you want to add a third? A forth? You really want a server that will act as an intermediary for all the clients.
