Java security in applet

As a novice of Java in general, I basically understand its security model,
particularily the inability to access the local file system from a browser.
However, one Java textbook I have seems to indicate that you can change 'permissions'
of sort, from the browser to possibly allow Java applets to write a file
to the local drive. I tried this in Internet Explorer, and there appears
to be a series of configs in IE's 'options' that would allow applets more
control in reading/writing files locally. However, after making the settings
in IE, my applet still doesn't appear to be able to write a file to the hard
drive. Does anyone know if this can work ( also it is for use on an inside
Intranet, where security is less of a concern ).Many thanks..

I think you need a digitally signed certificate if you want an applet
to play outside of the Java sandbox.
