Solution

  • When exporting your JAR file, you've to make sure you're also including the image files in your JAR file. For example: If you have a folder called 'res' containing the images, you have to check the checkbox before this folder in order to make sure this folder, and the images are being included.

    You might want to add some trouble shooting code. For example: Add some code that prints in the console if this image file exists. Export your JAR file, run your JAR via the console/terminal and check the result. If this shows you the image doesn't exists, you know it's a problem with your exported JAR file.

    You might want to try reaching the image as a resource steam, give the following code sample a try:

    java.net.URL logoOneUrl = getClass().getResource("logo.png");
Icon logoOne = new ImageIcon(logoOneUrl );
