Thread: ImageIcon Erratically Loading URL Image

I've got an interesting issue.

I have a class that extends JPanel and paints its background to be an Image that it gets from a URL. I am using ImageIcon to build and paint the image.

Now, while this works fine on my personal computer, for some reason it doesn't work on my computer at work. I have tested it with a bunch of different images, but all yield the same result.

Here is the snippet of code for when I build the ImageIcon:

    			try{
		    	URL url = new URL("http://www.java2s.com/Tutorial/JavaImages/ButtonwithImageIcon.PNG");
		    	ImageIcon anotherIcon = new ImageIcon(url);
		    	currentImage = anotherIcon;
		    	}catch(Exception ex){ex.printStackTrace(); 	}

And it is painted by saying:

public void paintComponent(Graphics g)
    {
    	super.paintComponent(g);
    	currentImage.paintIcon(this,g,(int)x,(int)y);
...}

Like I said, this works on my personal computer, but it would seem that ImageIcon is just not working in general on my work computer. What would be causing this?

You'd think they would have mentioned that in the API.

I am getting the following error:
