How to stopped applet from interruting my games . The applet shut down my game. I want it to stopped messing up my games. – user76910 Apr 16 '11 at 21:02

Only if either:

  • You explicitly grant the applet increased rights (this also requires the applet to be cryptographically signed, which in theory allows you to find out who wrote it and sue them when it turns out to be damaging)
  • Your JVM or Java browser plugin has a security hole that the applet exploits - unfortunately in recent years there has been a constant stream of such security holes being found.

(You can cryptographically sign your jars with a completely made up certificate. The users will see a differently coloured dialog.) – Tom Hawtin - tackline Feb 16 '10 at 23:53

No. Java has a built in security mechanism will prevents applets from performing certain method calls. See the documentation for Runtime#exec(), for example.
