Howdy,
You shouldn't be doing File I/O operations from JSPs or servlets in
general.
You can't get the server directory or webapp directory in a
servlet-specification compliant way. In fact, they might not even
exist, e.g. if you're running from a packed WAR on a database server.
The only directory you are guaranteed read/write access to is the
context temporary directory. It's available via (File)
getServletContext().getAttribute("javax.servlet.context.tempdir");
