            reader = new BufferedReader(new InputStreamReader(request
                    .getInputStream(), "utf-8"));
            String line = null;

            while ((line = reader.readLine()) != null)
            {
                sb.append(line);
            }
        } catch (IOException e)
        {
            e.printStackTrace();
        } finally
        {
            try
            {
                if (null != reader)
                {
                    reader.close();
