ImageIcon not displayed after creating jar

i'm trying to make a small project in java with no luck if i'm compiling the program with eclipse everything is good, but when i'm i creating the jar file i get a blank window

this is the image i declared for:

public ImageIcon BACKGROUND = new ImageIcon() ;

I have tried to do the following stuff:

1.

new ImageIcon("Images/wood.jpg").getImage());

2.

this.BACKGROUND.setImage(Toolkit.getDefaultToolkit().getImage("Images/wood.jpg"));

3.

this.BACKGROUND = new ImageIcon(getClass().getRe开发者_如何学运维source("Images/wood.jpg"));

4.

/** Returns an ImageIcon, or null if the path was invalid. */
protected ImageIcon createImageIcon(String path,
                                           String description) {

    java.net.URL imgURL = getClass().getResource(path);
    if (imgURL != null) {
        return new ImageIcon(imgURL, description);
    } else {
        System.err.println("Couldn't find file: " + path);
        return null;
    }
}

1 & 2 showing the images after compiling and 3 & 4 returns null

another think is that i'm using mac and when i'm working with windows no image is displayed after compiling.

Here's a small working example if that helps:

public class ImageIconApplet extends JApplet {
    public void init() {
        URL url = getClass().getResource("/images/WhiteFang34.jpg");
        ImageIcon icon = new ImageIcon(url);
        JLabel label = new JLabel(icon, JLabel.CENTER);
        add(label);
    }
}

The jar for the applet on that page contains two files:

/com/whitefang34/ImageIconApplet.class
/images/WhiteFang34.jpg

I'm not sure if you're deploying an applet or a desktop swing app, however the code to load images and the packaging requirements are the same either way.

I have something...

ImageIcon icon = new ImageIcon(getClass().getResource("/package/image.png"));
JFrame.setIconImage(icon.getImage());

Place this inside your constructor.

Are you sure Images/wood.jpg is present in the .jar file?

I suggest you unzip the jar file and make sure that it's there. Otherwise you'll have to revise your build scripts (or what ever technique you use) that builds the jar.
