Tracert or Traceroute in Java, without calling the OS

Question

I am developing a web application that will test the servers and will bring the result equal to a tracert of Windows or the traceroute Linux. I am developing in Java and using the commands mentioned in the following way:

I identify the server and call:

Runtime.getRuntime().exec("tracert " + hostCanonicalName);

After the execution I pick up the String and assemble a chart (Vis.js) with the path through which the request went.

I’ve already researched the web and I haven’t found anything in Java that does otherwise.

Is there any framework do that? I read something about HttpCliente and I did not receive a satisfactory reply.

I don’t want to use something directly related to the OS and I still can’t fully understand the commands, because with each IP I test it returns a different pattern.

I also searched and on the first page appeared interesting results. I do not know if they solve what you want but seem to be what you need:

• Independent API for traceroute (apparently discontinued as Victor comments)
• Code of a complete class (uses the following solution as dependency)
• A simpler solution - Jpcap (needs to work a little to get the result)
• Solution of ping found by Gordon Christie in the OS

Code:

import java.net.InetAddress;

public class Ping {
    public static void main(String[] args) {
        try {
            if (args.length != 1) {
                System.out.println("Usage: java Ping <hostname>");
                System.exit(-1);
            }
            String host = args[0];
            int timeout = 3000;
            boolean status = InetAddress.getByName(host).isReachable(timeout);
            System.out.println(host + ": reachable? " + status);
        } catch (java.net.UnknownHostException e) {
            e.printStackTrace();
        } catch (java.io.IOException ioe) 
            ioe.printStackTrace();
        }
    }
}

I put in the Github for future reference.

The ping is the basis of traceroute. From it it is possible to construct an algorithm to plot the route.
