Security Restrictions
Applets are said to live in a sandbox. Living in the sandbox
imposes the following security restrictions:
Applets cannot run any executable code on the local machine.
Applets can neither read nor write to the file system on the
local machine.
Applets can only establish network connections with the host
which they were downloaded.
All windows that pop up from an applet have a warning message
that alerts users not to enter sensitive information.
The restrictions are enforced by a SecurityManager
class instance on the browser. Each browser may have different security
restrictions.
