Jar get image as resource

Question

I\'m trying to get load an image from my jar. But no matter what string I supply for getResource() it always returns null.

try {
    System.out.println(Boots         


        

Answer 1

From the stack trace I see the Bootstrapper class lies in net.sharpcode.crawler package. It means the following path ./img/logo.png will be resolved to /net/sharpcode/crawler/img/logo.png. I guess /img is a top level directory, so either use absolute path:

Bootstrapper.class.getResource("/img/logo.png")

or load via ClassLoader:

Bootstrapper.class.getClassLoader().getResource("img/logo.png")

Answer 2

this.getClass().getResource("/net/sharpcode/crawler/img/logo.png")

Answer 3

Get rid of the "./" part - just use:

Bootstrapper.class.getResource("img/logo.png");

... that's if it's relative to Bootstrapper.class. If the img "directory" is in the root of the jar file, use

Bootstrapper.class.getResource("/img/logo.png");
