But doesn't that imply that I need to set up a server on my computer and then copy the files to that server? Or is there some simple way to use localhost to point to a specific file or directory on my hard drive that I've forgotten? I'm not coming up with anything like that in my Google search for localhost examples....

It's been a few years since I last messed with localhost and it's just not coming back to me clearly. Google isn't getting me to the right place yet either.... Sorry for being so dense! I really just want to be sure that I can get a trivial program using JavaFX to work both on my laptop and on a server before I start to put major time into learning how to write JavaFX code for myself. -- Rhino
