I think Marcel has the right of it.  You should be using getResource() 
(or getResourceAsStream()) to load this file.

However the basic problem is that you need to include the file.  You 
should be using a build script that automatically copies the file.  Most 
IDEs will do this *if you put the image in the source directory.*

I see here you've deliberately excluded the image from the source. 
That's normally wrong.  Try something like:

src/my/stuff/Abc.java
src/my/stuff/abc.png

Most build system will now automatically figure out that you want the 
PNG file to be included in the Jar file, and do the copy for you.  If 
you're using entirely home-rolled tools, you'll have to do the copying 
yourself, but at least add it to an automated build script so you don't 
have to do the copy manually each time.

Notice on this page how they do that exact thing just by calling 
getResource():
