Design of File Choosers

I would like to have a file chooser that lets me look at all of the entries
in a Jar (and maybe a Zip file) the way that a standard JFileChooser lets me
look at all of the entries in a directory. Ideally, the jar could be located
in the filesystem, on or off the classpath, or even online at a location
described like this: jar:http:/xyz.com/images/photoJar!/

Standard JFileChoosers don't have any constructors for finding files in a
jar. Would I be able to get that functionality by subclassing JFileChooser
and adding new constructors that handle files in jars? Or would I have to
create a whole new class that reads jars?

I'd like to leverage the functionality built into existing JFileChoosers if
possible but my theory is weak in some areas and I can't quite figure out
how to do so.

Can anyone suggest a good approach?
