Send multiple strings over TCP - Like messenger service

Question

Hello all Java Coders,
I'm new with TCP programming.
I'm beggining to learn about TCP and sockets connections in Java. In order to achieve this, I was coding a mini-program so I can learn a little bit about this.
I'm trying to make a simple TCP program.
The server sends a string to a client...
I already searched for a couple of hours in google and so on, about what I'm doing wrong.
[The server code (Just click)|http://pastebin.com/m39fd1273]
[The client code (Just click)|http://pastebin.com/m57471803]
I hope that someone can help me with this and, if you have patience, please tell me the reasons my code doesn't work.
Many thanks,
Freiheitpt
P.S.: I think that the problem is on the server side...

Sorry jverd.
I was just trying to put things organized.
Well, I can't get the String to be sent to the client.
No error occurs.
Server:
       try {
            srvr = new ServerSocket(1234);
            System.out.println("Connecting...");
            skt = srvr.accept();
            System.out.println("Connected!\nPreparing data exchange...");
            stream = skt.getOutputStream();
            out = new PrintWriter(stream, true);
            System.out.println("Done!\nReady to Send!");
        } catch (IOException ex) {
            System.out.println("Ups, didn't work!");
            System.exit(1);
        while(!data.equalsIgnoreCase("end")) {
            System.out.print("String to send: ");
            data = input.nextLine();
            System.out.print("Sending string: '" + data + "'\n");
            out.print(data);
        }Client:
        try {
            skt = new Socket("localhost", 1234);
            System.out.println("Connecting...");
            if (skt.isConnected()) {
                System.out.println("Connected!\nPreparing data exchange...");
                stream = skt.getInputStream();
                inputStream = new InputStreamReader(stream);
                in = new BufferedReader(inputStream);
                System.out.println("Done!\nReady to Receive!");
            } else {
                System.out.println("Server not available!\nExiting...");
                skt.close();
                System.exit(1);
        } catch (IOException ex) {
            System.out.println("Ups, didn't work!");
            System.exit(1);
        while (!data.equalsIgnoreCase("end")) {
            while(!in.ready()) {}
            data = in.readLine();
            System.out.println("Received String: '" + data + "'");
        }
