From which Jar is a class Loaded

I post this for future reference.

public class Main {

public static void main(String[] args) {
System.out.println(findJar(System.class));
}

public static String findJar(Class clase) {
String name = clase.getName();
name = name.substring(name.lastIndexOf('.') + 1) + ".class";
String jar = clase.getResource(name).toString();
return jar;
}

}
