Accessing Resource files in java

what's the best way to access resource files in java?

I am just trying some java3d examples and it uses a resource loader that creates an URL object with the file name,but i can't get it to work, any suggestions?

BufferedInputStreamAccessResource bisar = new BufferedInputStreamAccessResource();
a real java programmer would write it like this:
BufferedInputStreamAccessResource MyBufferedInputStreamAccessResouceWithANameThatIsSeventyFiveCharactersLong = new BufferedInputStreamAccessResource();
