Java APIs

allright this is my server code:

        ServerSocket serverSocket = new ServerSocket(27016);
        while (true) {
            Socket clientSocket = serverSocket.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
            BufferedWriter out = new BufferedWriter(new OutputStreamWriter(clientSocket.getOutputStream()));

            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                System.out.println(inputLine);

            }
            out.write("hello client!");
            out.flush();
        }

client code:

$fp = fsockopen("67.184.204.230", 27016, $errno, $errstr, 5);
if (!$fp) {
    echo "$errstr ($errno)";
} else {
    fwrite($fp, "hello server\r\n"); // send data to server
    echo fread($fp, 200); // @@@@ read output from the server
    fclose($fp);
}

the problem is that I get no output from the server at all, the client script runs for about 10 seconds and then apparently it times out and all i get is a "white" empty page, but the weird thing is that the server DOES get my "hello server" message...
so what could be the problem? Believe me i made hundreds of google queries and apparently no one has ever tried this in the history of the internet.

please help?
