Applet Security (File Transfer) Questions

P: n/a
I've looked through a few books and various web sites. I'm still not clear
on this and would like to make sure I have this right.

I would like to use an applet in a web page. When the user presses an
"UPLOAD" button, a file chooser would appear, the user could select a file,
then the applet would read the file in and (instead of a regular upload),
e-mail it to a specific address (a program will be reading the emailed
files and processing them).

I think I read that as long as the user specified a specific filename (like
with a file chooser) and I converted the filename to a URL, I could read
that file without having a signed applet. Is this true? Can I read in a
specific file from an applet and e-mail it somewhere?

And, if I can't, it looks like it is really easy to sign an applet. Is it
as easy to create a signed class as it looks? If I upgrade the applet, do
I have to have it re-signed or done over so the new version is recognized
too?

Thanks!
