I am trying to a stream bytes by byte to a embedded display. It worked for text and Image but when i share it with Video, video getting corrupted.

I run the class offline and find its working but when sending on HTTP if fails. Below is ServerSide and ClientSide code

Server Side

byte[] b = readByte()// my function which return bytes of Data
ServletOutputStream stream = httpServletResponse.getOutputStream();
stream.flush();
stream.write(b);
stream.flush();

Client Side

            URL url = new URL("localhost" + fp);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setDoInput(true);
            conn.setDoOutput(true);
            conn.connect();
            InputStream is = conn.getInputStream();
            System.out.println("Connection Open");
            int pos = 0;
            byte[] b = new byte[buffLength];
            while (pos != -1) {
                pos = is.read(b, pos, b.length - pos);
            }
           write2File(b);
