Did you get the Unlimited Strength Jurisdiction Policy Files from Sun?

Hi All, I am new to the encryption world. Going through Cryptix last couple
of days.

My need is to get my data encrypted with PGP encryption. Can I just get
this
done with out using any third party api?
I am intending to achieve PGP encryption by using SunJCE provider? examples
would help a lot.

I tried to run the Cryptix examples on jre 1.4.2, 1. when i run the
GenerateAndWriteKey.java with "Strong" but  limited crypto it works fine.
But when I switch to  "unlimited strength" cryto I am getting following
errors

2. With the Keys generated using "Strong" encryption, if I run Encrypt.java
I am getting following error.

please let me know what am i missing ???

thanks in advance
