How do I change the default application icon in Java?

I'm using NetBeans, trying to change the familiar Java coffee cup icon to a png file that I have saved in a resources directory in the jar file. I've found many different web pages that claim they have a solution, but so far none of them work.

Here's what I have at the moment (leaving out the try-catch block):

URL url = new URL("com/xyz/resources/camera.png");
Toolkit kit = Toolkit.getDefaultToolkit();
Image img = kit.createImage(url);
getFrame().setIconImage(img);


The class that contains this code is in the com.xyz package, if that makes any difference. That class also extends JFrame. This code is throwing a MalformedUrlException on the first line.

Anyone have a solution that works?

Answer
java.net.URL url = ClassLoader.getSystemResource("com/xyz/resources/camera.png");

May or may not require a '/' at the front of the path.
