This might be due to the fact that you are installing the applet
locally.

How are you invoking the applet?

Are you loading this URL into a browser?

http://java.sun.com/sfaq/example/writeFile.html

or, are you copying the applet to your computer, and then running it?

Unless you have set up your system to accept signed applets, and
unless you have it configured so that signed applets are allowed to
write to disk, then an applet cannot read or write to your local
disk. Probably you have seen this page already, but check out
http://java.sun.com/security/signExample/

*If* you installed the applet on your local computer, and if you are
accessing it that way, *then* the applet is treated like a part of the
local trusted file system, and it has full access. This is one way
you can have an applet read and write files on Explorer or Navigator
today.

Down the road, you will be able to configure your system to allow
particular applets to read and write particular files, based on where
the applet came from and who signed it. This is coming in the next
release.
