Hi,
I’m having problem loading Url images from jar file.
The image files are in the same package as the Class

By using this source loading resource in eclipse works fine:


for(int i=1;i<=6;i++){
URL url =CanvasResourceViewеr.class.getClassLoader().getResource("r"+i+".png");
this.resourceImages[i-1] = ImageIO.read(url);
}

But when i Export it in jar file i get an error:
java.lang.IllegalArgumentException: input == null!
at javax.imageio.ImageIO.read(Unknown Source)
at client.framework.CanvasResourceViewer.(CanvasResourceViewer.jav
a:22)
at client.local.GameClient.(GameClient.java:65)
at client.local.Run.main(Run.java:25)
Any ideas ?
