gcjwebplugin:
a plugin for the execution of Java™ applets in web browsers
WARNING:
The current version does not provide a security manager capable of handling Java (tm) applets. Applets have UNRESTRICTED access to your computer. This means they can do anything you can do, like deleting all your important data.
