在浏览器中运行时，Java Applet图像不会显示

Question

I finally managed to get my java applet to run in my browser, however I now face the issue that none of my images will display. The only thing that displays is black text that is drawn in the screen in the applet.

In order to get the applet to work at all, I had to export as a jar and sign it myself. Now, I'm wondering why it is that the images won't display. I checked and the jar file does include all the image files. Likewise, the applet runs perfectly well in Eclipse.

What could be the issue here?

mainscreen = new ImageIcon("main.png").getImage(); is the first image that should be accessed.

Additionally, all of my classes including the applet class are in packages. The images are all outside of those packages.

ImageIcon("main.png").getImage() suggests that you are trying to load an icon from a File , which is not the case for applets

With embedded resources you need to use getClass().getResource("/path/to/resource") . This will allow your application to search within it's class path to find the resource...

Try something more like ImageIcon(getClass().getResource("/main.png")).getImage() , assuming that the main.png resides within the root folder of the jar file...
