             for
               (int i=0, n=selectedFiles.length; i<n; i++) {
                     System.out.println("Selected: "

+ selectedFiles[i].getName());
System.exit(0);

Answer 1

You don't, it's Swing code, client side only. The JFileChooser will open up a file dialog used to open or save files on the client machine: you have no access to the client filesystem from a jsp.
