How to refer to the jar filepath relatively?

wtver87

Hey guys,

I'm finishing up on my newest apps and I need to store a file in a location of my .jar. So here's my situation:
I got a jar at C:\

so essentially, in the command line i made this call:
javaw -jar C:\myjar.jar C:\Mydocs\myfile1

I need to store something at C:\ but if I use relative path, the file is stored on C:\Mydocs\ instead. I cannot use absolute path however since when my user install the apps, I couldn't possibly force them to install on a specific location, I want it to be with the .jar.

Any idea on how to do this?
Thanks

My English is not yet too sophisticated so I did not quite get what you are asking. If you could go into it again it would be helpful and I can tell you an answer or idea would come from all sides...

Also, if you have a pseudocode or outline, please add here for looks. Be sure to fetch results within this forum, something may have been posted.

See you soon!

 import java.net.*;

import java.security.*;
 
public class FromWhere {

    public static void main(String[] args) {

        Class cls = FromWhere.class;

        ProtectionDomain domain = cls.getProtectionDomain();

        CodeSource source = domain.getCodeSource();

        URL url = source.getLocation();

        System.out.println(url);

    }

}

This code may help. It works if your class file is not jarred or if the class file is in a jar that is in the file system.

An alternative is to use the user's home directory:

String homeDirectory = System.getProperty("user.home");
