In order for an applet to read and write to a local
file system, it's "sandbox" must be set up correctly. Your program will
work fine if you either:
a) convert to an application
b) create a signed applet and pay the "Gods"
of verisign $400 a year.
c) modify your applet permissions from your
applet control panel (How do this varies from system
to system, complicating
matters when trying to deploy and writing the user manual! ;-) .)
If you find out a d) please let me know
;-)

Helllllllllllllllllp!
You cannot access local files from an Applet due to security
restrictions.
Your code should work fine as an application.
