For an applet to get permission to access any URL on the Web (which is what you need), you will need to "sign" your applet's jar file before uploading it to the Gallery. This is not simple, and may well cost real money. Applet signing is described in many places, including here and here. If you want other users to run your scenario, you'll need to buy a "code signing certificate" that th

Elevator
