This isn't what you want to do. What you want is a POST with the content
of your file in the request body -- NOT in the request parameters.
That isn't to say that your attempt won't work... it's just that there
are many limitations on passing information through a URL (such as any
maximum URL length limits set by your web server).

This is a very odd way to do things. Why are you saving a file AND
serving a page to save files in the same servlet?

So, do you get a file in C:\TEMP\whatever? If so, what is the content of
the file. You said "a null"... do you mean a 0 byte file? Or the word
"null"?
