STILL need help w. Security Exception

[Steve Burrus]

Hi all again, I still find myself in need of some help/assistance with
always getting the Java Exception "java.security.AccessControlException"
when I try to see a compiled Swing applet in my favorite web browser!!!
Here is a dump from the Java Console for your inspection :

"Java(TM) Plug-in: Version 1.4.1_02

It's telling you exactly what the error is. You're evidently trying to
read a local file (tiger.gif) on the local filesystem from an unsigned
applet.

AccessControlException

see http://mindprod.com/jgloss/errormessages.html

Roedy, while I really do appreciate your attempted help/assistance with
my problem with getting that Java Exception, I must say that you have
sent me that link to your website before, and I went to it, BUT it
really didn't help me out at all!!!

I mean, I never saw any explicit reference to my specific problem with
getting that "javax.security. AccessControl java.io.FileNotFoundException"!!

Do u feel like helping me out of my "terrible" [sic] problem or not, I
might directly and pointedly ask you right now??? And after you have
answered my question of you, I would like to know just what your
"mindprod.com" is??? Are you based up there in Canada??? In what city
anyway? But back to this exception, I HAVE corrected this problem in
the past by putting this line of code into the file : (now this is
trying to get a graphic file seen. )

"ImageIcon ic = new
ImageIcon(getClass().getResource("['nameofgraphicfile']"));
