You don't have to check for type of operation system to use proper slash. Class File provide separator which automaticaly detect OS and apply relevant slash.
For example if your file return absolute path as C:\Test to create new File you do
which will return then absolute path as C:\Test\fileName.In case of unix file return absolute path home/Test return would be home/Test/fileName
Sun tutorial aviable here
I'm not clear how you retrive the files from user pc, but once you get file source destination which you can have as File or String(in case of String you have to create new File out of it) you call method getName()
whitch return String with the name of your file
For example if your file return absolute path as C:\Test to create new File you do
File fileTwo = new File(file.getAbsolutePath() + File.separator + fileName);

anyone writing such crap in a JSP gets what he deserves when (and it will) it doesn't work.

Maybe as an example of what not to do?
Or for the IT version of the freaky horror show?

Yes, but the Rocky Horror Picture Show is, at least, funny. That's just scary, and, maybe, a little sad. ;-)
