Applets normally do not have access rights to things such as exec()
since that would be a *big* security hole (large enough to drive a truck
or two through without even looking)
Anyway, applets can do this if they are given the security clearance
which can happen with signed applets or applets run from local servers
with security turned off from the applet viewer.
