Client/Server Socket problem

Hi, I have am trying to write a simple client/server, where the client
reads in a line of text and sends it to the server. the server
capitalizes the text and sends it back...but the server is never
finishing reading from the client socket input stream...any ideas?

client (snippet):

                // connect to the server
                sock = new Socket("127.0.0.1", 8000);

                byte[] bytes = msg.getBytes();

                // send the user input to the server
                BufferedOutputStream bos = new
BufferedOutputStream(sock.getOutputStream());
                bos.write(bytes);
                bos.flush();

-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

server (snippet):

            ServerSocket sock = new ServerSocket(8000);
            while (serving) {
                try {
                    Socket client = sock.accept();
                    int val = -1;
                    BufferedInputStream bis = new
BufferedInputStream(client.getInputStream());
                    while ((val = bis.read()) != -1) {
                        System.out.print((char) val);
                    }
                    System.out.println("done reading from client...");

                    BufferedOutputStream bos = new
BufferedOutputStream(client.getOutputStream());
                    bos.write("GOT IT!".getBytes());
                    bos.flush();

                    client.close();
                } catch (IOException e) {
                    e.printStackTrace();
                    serving = false;
                } finally {
                    if (sock != null) {
                        try {
                            sock.close();
                        } catch (IOException e) {}
                    }
                }
            }
            sock.close();

thanks
