I can't access my images!!!

Question

Greetings
First I thought it might be an error in my code but upon executing the following code that calculates the images's height and width it returns -1 values? the test.jpg exists in the same folder as the ImageXY.java file and it's size is 100 * 100, I tried creating many other images, but the same problem persists. i'm using IDE3.6 with jdk1.4.2_05, although i coded it using dos prompt too.
import java.awt.*;
import javax.swing.*;
public class ImageXY
     public static void main(String[] args)
         Image image = Toolkit.getDefaultToolkit().getImage("test.jpg");
         ImageIcon icon = new ImageIcon(image);
         int height = icon.getIconHeight();
         int width = icon.getIconWidth();
         System.out.println("height"+height);
         System.out.println("width"+width);
[/code]
It's a really strange problem, I know there's something wrong with my java , can any body help?

thank you ChuckBing for your fast reply. i'll try it soon
I was trying to compile several java applications and it appeared that the problem is with NetBeans, compiling any file with NetBeans returns no errors, but executing don't display the image.
while compiling and executing in the dos window returns fine results!?
moreover, it doesn't matter if the images exist in the same folder in a different folder like in packages, all the tests that I did proved that the problem is with IDE. Does it have a different method to deal with images?
I'm starting to hate this IDE,
