Subject: [j2ee] Zipping a file in a client machine with an applet


Hi all,
I have to do an applet which zips  1-1.5 MB files before sending to our
server to reduce the net traffic.
I have looked around and saw that I must sign this applet's cab file
with our certificate and I did it but it is already given security
exception because of playing in the sandbox.
What do I need different for achieving this purpose?
Is there anysite to find about secure applet examples?
Best regards,
Burak
