Writing/reading HTTP with plain sockets

Question

Hello,
I�m trying to send an HTTP request and read response with a plain socket, not URLConnection.
My code below is not working - bufferedReader.readLine() returns null.
If I change to URLConnection everything works as expected.
What is wrong in my code?
Thanks in advance.
public static void main(String[] args) throws IOException {
        /* -- THIS CODE WORKS --
        URL url = new URL("http://localhost:8080");
        URLConnection urlConnection = url.openConnection();
        OutputStream outputStream = urlConnection.getOutputStream();
        InputStream inputStream = urlConnection.getInputStream();
        // Tomcat is running on localhost port 8080
        Socket socket = SocketFactory.getDefault().createSocket("localhost", 8080);
        OutputStream outputStream = socket.getOutputStream();
        InputStream inputStream = socket.getInputStream();
        // send request
        OutputStreamWriter writer = new OutputStreamWriter(outputStream);
        writer.write("GET /");
        writer.flush();
        // read response
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder strBuilder = new StringBuilder();
        String str;
        while ((str = bufferedReader.readLine()) != null) {
            strBuilder.append(str);
        // print response
        System.out.println(strBuilder);
        socket.close();
    }

Your HTTP request-line(s) syntax is quite wrong.
