Get URL for class

Question

Is there any Java API that will allow me to get the URL of the JAR file or directory that contains a particular class? I'm looking for somrthing similar to getResource(String) in the Class class that will tell me which JAR file or directory the class loader is pulling stuff from.

Answer 1

The URLClassLoader has a method called getURLs(). I hope this snippet of code could help!
import java.net.URLClassLoader;
import java.net.URL;
import java.net.MalformedURLException;
public class Main {
    public static void main(String[] args) {
        try {
            URL[] urls = new URL[3];
            urls[0] = new URL("file:p/");
            urls[1] = new URL("http://java.sun.com/");
            urls[2] = new URL("file:/tmp/c.jar");
            // Create URLClassLoader
            URLClassLoader cl = URLClassLoader.newInstance(urls);
            URL[] retUrls = cl.getURLs();
            for (int i = 0; i < retUrls.length; i++) {
                System.out.println(retUrls[ i ]);
        } catch (MalformedURLException e) {
            e.printStackTrace();
