Martin is correct :o) Also be aware that very very large files can exceed the setting of Java temp space (memory) allocation is some containers and crash them.
One approach that works is to write a simple file upload script in Perl. This allows you to check content-type, size, etc. and reject the upload before trouble happens. It is also platform independent to a "reasonable" degree. Just another $.02 worth...
