Dear sir or madam:

Sorry for bothering you- I am a student at the University of Texas at =
Arlington=20
currently writing my thesis on the benefits of JAVA in scientific =
programming.
I was recently investigating the security features in JDK 1.14, and ran =
across
the signed applet example ("Duke").

I successfully read the digital signature Duke.x509 and ran the signed =
applet
on both a Windows 95 machine (at home) and a Windows NT 4.0 machine (at =
work).

However, when I tried to duplicate the steps involved in creating a =
digital signature
and signing the applet, I was not able to get the Windows NT 4.0 machine =
to write
to my local disk (a security exception was thrown). I had no problems =
doing this
on my win95 machine at home. =20

Are there any peculiarities between the Windows 95 and NT 4.0 =
implementations?
Has the example been successfully tested under both operating systems? =
I am using
JDK 1.14 on both machines, and the class path is correctly defined on =
both machines.

I dont understand why I have no problem with Sun;s Duke.x509 file, but =
when I try
my Duke.x509 (which I created and tested successfully on my win95 =
machine) on
the NT 4.0 machine, the example continues to throw a security exception.

Any advice would be greatly appreciated. I'm using the doit script =
provided in the
example, and understand the basic javakey and jar requirements.

Thanks you,
mike=20
