public static String getStringFromInputStream(String filepath) {

         BufferedReader br = null;

         StringBuilder sb = new StringBuilder();

         String line;

         try {

             br = new BufferedReader(new FileReader(filepath));

             while ((line = br.readLine()) != null) {

                 sb.append(line);

             }

         } catch (IOException e) {

             e.printStackTrace();

         } finally {

             if (br != null) {

                 try {

                      br.close();

                 } catch (IOException e) {

                      e.printStackTrace();

                 }

             }

         }

         return sb.toString();
