Hi Sarah,
Thanks for your email. Yes this project is still active, in fact many of its features are being added to JSF 2.0.
This project does not provide many components, so if you're looking for a component to allow uploading files from the client (browser) to the server, I suggest looking at Woodstock's, Ice Faces's, or
Scales's download components. Jason Lee is a JSFTemplating dev on this alias, and also created the Scales download component -- so he may have some more advice for you.
If you want the server to upload to the client, then JSFTemplating might be a good choice for you. JSFT has a feature called "FileStreamer" that helps you stream any content from within a JSF environment. Jason and I have both written blogs about this feature. Let me know if you need more details
