First of all, please follow the conventions of the mailing list and
prepend the name of the relevant component to the subject line, in
square brackets. That way, people know at a glance which component
your question is about.

Why? I mean, why do you need to *read* them in several different
functions? Why can't you read them once and then pass them around?

That's actually what you're going to have to do. Once you've called
parseRequest(), the request input stream has been consumed, and cannot
be read again. This is not something that FileUpload can do anything
about - it's just how streams work.
