Java EE (Java Enterprise Edition) General Discussion

Hi, I have read through the user guide but I don't understand what are the steps as to implementing the functions...

http://commons.apache.org/fileupload/using.html

How do I Create a servlet to read the contents(filename) of te dir where the files are, then create a collection (ArrayList for instance) with the files path and send this collection back to a jsp page.In jsp page, iterate through the collection and build the links (with scriptlets or c tags)

Can help? Thanks for the guidance!
