URL file chooser

I would like to modify my project to allow customers to specify
configuration files with URL syntax rather than straight files to allow
more flexibility in accessing remote configuration options. On my
server side all worked very well but the GUI guys are not sure how to
approach this. I don't have much of any experience on the GUI side of
Java myself. I guess they are currently using a FileChooser widget to
allow the customer to choose the configuration file. Is there an
equivelent widget that works for URL syntax?

Thanks!
