Fetch Data from URL

[Rajkumar balakrishnan]

We are developing a web application where user can fetch data's from their mobile phone just by typing the reference number and send to a number. If he send a message it will hit the SMS API and we can get that details from a unique URL assigned the SMS provider to us. I am using the below code to fetch the data but it always returns null. I sent around 5 messages to check that but still i am getting null value. The URL is tested and it works fine

Code is

package com.sms.utility;

import java.io.*;
import java.net.*;

public class WebCat {
    public static void main(String[] args) throws Exception {	
    	 try{
    	      URL url = new URL("http://smsurl");
    	      URLConnection connection = url.openConnection();
    	      connection.setDoInput(true);
    	      System.out.println("Connection Details are : "+connection.getContentLength());
    	      InputStream inStream = connection.getInputStream();
    	      BufferedReader input = new BufferedReader(new InputStreamReader(inStream));
    	      System.out.println("Output would be : "+input);
    	      String line;
    	      while ((line = input.readLine()) != null){
    	         System.out.println(line);
    	      }
    	   }
    	   catch (Exception e){
    	      e.printStackTrace();
    	   }
      }
}
