You can't call methods on a null object reference.. you actually need to have a URL first...  you haven't shown any object being assigned to your URL reference.

What does this have to do with Java 3D?

Thanks to everyone!

I solve my problem la!
it is not the URL object problem,it can point to
a url.
I make a mistake in string.
I use URL.toString().substring(index) to solve.
