Question

I am using Eclipse, and I wish to export some images in the “img” source folder along with my .jar, so they show up in the JAR.

My Heirarchy is :

Project>src>Package>FILE.java

Then in project is another source folder called :

img>IMAGE.png

I am currently linking to the images using :

lblNewLabel_1.setIcon(new ImageIcon("img/logo1.png"));

And that works fine, until I export it.

I am exporting it as an Runnable JAR file with Extract required libraries ticked, as the middle one will not allow the .jar to open. Extract allows it to open, but the images do not show.

Path are not the same when you load data inside a JAR.

You can use this method to load image when you run from a JAR:

/**
  * Create an instance of ImageIcon with the given path
  * @param path  String - path of the image
  * @return  ImageIcon - ImageIcon made with the image at the given path
  */
private ImageIcon createImageIcon(String path) {
    if (path != null) {
        URL tmp = getClass().getResource(path.replace("\\", "/"));
        if(tmp!=null)
            return new ImageIcon(tmp);
        else
            return new ImageIcon();
    } else {
        System.err.println("Couldn't find file: " + path);
        return null;
    }
}
