Socket problem - readline won't work properly

Question

I try to code a client and server connection using socket. The problem is my client can\'t read the response from the server (it hangs on the readline).

Here is some

OK, I made several editing in the code and now it run nicely :

The server :

    try {
        // Create the server socket.
        portNumber = Integer.parseInt(myParam.get("socket.portNumber"));
        mainSocket = new ServerSocket(portNumber);

    } catch (IOException ioe) {
        System.out.println("Error Message : " + ioe.getMessage());
    }

    // Accept connections    
    try {
        clientSocket = mainSocket.accept();
    } catch (IOException ioe) {
        System.out.println("Error Message : " + ioe.getMessage());
    }
    BufferedReader in = null;
    PrintWriter out = null;

    while (true) {
        try {
            in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
            out = new PrintWriter(new OutputStreamWriter(clientSocket.getOutputStream()));
            //Read The Message
            **StringBuffer buffer = new StringBuffer();
            while (true) {
                int ch = in.read();
                if ((ch < 0) || (ch == '\n')) {
                    break;
                }
                buffer.append((char) ch);
            }
            String clientRequest = buffer.toString();**

            SocketServerThread st = new SocketServerThread(clientRequest, out);
            st.start();
        } catch (IOException ioe) {
            System.out.println("Can't accept connection. Error message :" + ioe.getMessage());
        }
    }

I change the readline with read and it work, so the assumption that "\n" is the problem is correct.

The thread : a minor change in the thread (remove the reading request part since I already done that in the server)

The Client: change the readline into read just like the server one.

Thank you all for the help
