[RESOLVED] Complex loop question on a client app

[Pouncer]

Basically, I want my client to be continously able to send messages to the server, but *also* at the same time be able to recevie and display any messages from the server. This is the loop I have in its current state on the client

	while (true) {
	    try {
		System.out.println("Enter a message to send to the server:");
		nextline = stdIn.readLine();
		if (nextline != null) out.println(nextline);

		fromServer = in.readUTF();
		if (fromServer != null) System.out.println("From server " + fromServer);
		
		else {
		    out.close();
		    in.close();
		    csocket.close();
		    stdIn.close();
		}
		
	    } catch (Exception e) { }
	}

It asks me to enter a message, I enter something and it sends it to the server.. perfect. BUT it just doesnt do anything after that, it just halts. I want it to print 'enter a message' again, and also be able to print messages from the server. Hope someone can help.
