Loading resources from jar - problem

Question

I've got a problem when loading resources from jar.
My code:
package game.player;
import javax.swing.ImageIcon;
import java.awt.Image;
import game.map.Map;
import game.map.MapReader;
import game.emptyclass.EmptyClass;
import java.net.URL;
public class Data
    ClassLoader cl = EmptyClass.class.getClassLoader();
    Image image1 = new ImageIcon(cl.getResource("data/sprites/man6.png")).getImage();
    Image image2 = new ImageIcon(cl.getResource("data/sprites/man5.png")).getImage();
    Image image3 = new ImageIcon(cl.getResource("data/sprites/man4.png")).getImage();
    Image image4 = new ImageIcon(cl.getResource("data/sprites/man3.png")).getImage();
    Image image5 = new ImageIcon(cl.getResource("data/sprites/man2.png")).getImage();
    Image image6 = new ImageIcon(cl.getResource("data/sprites/man1.png")).getImage();
    public Image tile1 = new ImageIcon(cl.getResource("data/maps/test/tile1.png")).getImage();
    public Image bg = new ImageIcon(cl.getResource("data/maps/default/bg.png")).getImage();
    public Map map = new MapReader(cl.getResource("data/maps/test/test.map").getPath()).getMap();
    public int getImageWidth()
        return image1.getWidth(null);
    public int getImageHeight()
        return image1.getHeight(null);
}I get a NullPointerException.
Thanks in advance!

Hi ,
getResource() method argument is not begin with the
character '/' , ex.
Image image1 = new
ImageIcon(cl.getResource("/data/sprites/man6.png")).ge
tImage();
I thought of that, but it's not applicable here because getResource is being called on the ClassLoader, not the Class.
