Answer 1

if the applet runs locally, and you want to connect to your DB locally with the applet, it won't work (except if you adjust the security settings of your browser, maybe). That's because applets don't have access to the computer they're running on (except some information), since that would mean that any applet could just access your computer, so, it's not possible for security purposes.
On the other hand, they don't have to right to connect to anything, except the server they're downloaded from ( so the webserver's ip).
But I'm not sure about connecting to a DB through JDBC that way.
