Applet Security (File Transfer) Questions

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!

Hal

Hello, I've been reading up on security in Java Applets and whilst I understand the concept, I can't successfully get my applet to read a file on my local machine. I discovered from http://java.sun.com/sfaq/#read: ----- Sun's appletviewer allows applets to read files that are named on the access control list for reading. The access control list for reading is null by default, in the JDK. You can allow applets to read directories or files...

Hy! My next problem is to make an applet from my program. I have just add the "extend applet" to my class and removed the main-method by the start-method of the applet. I was thinking that this is enough, but it does not work, the file does not appear on the server. I have tried to start the applet local and also from the server, but it does not work. Here is the code: *****************************************

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.
