Best Tool for Mass File Uploads?

[eluser]Tom Schlick[/eluser]
Hello all,

im creating an application for schools and am trying to think of the best tool for mass photo uploads. Im thinking either Java Applet based or Flash based. does anyone know of a good tool that is flash or java based and allows you to upload alot (hundreds) or files at a time? It must be able to select alot of files (or folders of files) at a time. Kind of line facebook's java based photo uploader (dont know if they still use it or not)

Thanks

I'm not sure myself, but another great example is box.net. They have a click and drag version and I think they built 2 versions - one in Flash and the other in Java.
