Answer 2

Below code works for me.

StringBuilder stringBuilder = new StringBuilder(); BufferedReader bufferedReader = null; try { String streamLength = request.getHeader("Content-Length"); int streamIntLength = Integer.parseInt(streamLength); InputStream inputStream = request.getInputStream(); if (inputStream != null) { bufferedReader = new BufferedReader(new InputStreamReader( inputStream)); char[] charBuffer = new char[streamIntLength]; int bytesRead = -1; while ((bytesRead = bufferedReader.read(charBuffer)) > 0) { stringBuilder.append(charBuffer, 0, bytesRead); } } else { stringBuilder.append(""); } } catch (IOException ex) { throw ex; } String body = stringBuilder.toString(); //System.out.println(body); byte[] bytes = body.getBytes(); System.out.println(StringUtils.newStringUtf16Le(bytes));
