| Why is demo.jar looking in ./icons instead of in demo.jar?

demo.jar doesn't look anywhere.  Your app specifies to look in the
filesystem (see highlighted path above).  What you want is (in Java) :

// you need the 'getResource' method with is found in instances of the
// 'Class' class
URL path = (new Object()).getClass().getResource( "/icons/right.gif" )
// now make the icon getting the gif from the url
ImageIcon = new ImageIcon( path )


If you are doing it from the Jython side use :

path = java.lang.Object().getClass().getResource( "/icons/right.gif")
icon = javax.swing.ImageIcon( path )

and it should work.  Be sure and print the url if it doesn't work so
you can see where getResource() thinks that resource is.
