The typical non-Flash way is to do the file upload in an iframe. The iframe doesn't have to contain more than a simple form with a single file field. There's some trickery involved getting the UI to work seamlessly and synchronizing the backend, especially if you need it to look like it operates together with some other forms and form fields, but I'm sure you are more than capable to handle it :) I recall building an iframe-based upload component for Tapestry 4 at some point.
