I am studying webcard material(see the attachment). And I saw the main() function in the java card applet.
Why is the main() function in the java card applet ?
I have never saw this in other applets. How strange it is.

two questions about waitExtension
I have two questions about waitExtension function.
Q1: If the card doesn't implement automatic timer mechanism, how long is the waiting time waitExtension function request from CAD?
Q2: If there is a long-playing processing, how should I request ?
Thanks a lot.
