Java 1.4 and AES Algorithm PLEASE HELP!!

Question

I hope this question has not already been asked. I have spent a long time searching the archives and documentation.
I am attempting to migrate from jsdk1.3 to jsdk1.4 but have come up against the following problem.
I need to create keys and encrypt files and was doing it by using the following:
import java.security.*;
import cryptix.provider.key.RawKeyGenerator;
import xjava.security.KeyGenerator;
And in my code am using:
SecureRandom rnd = new SecureRandom();
rnd.nextInt();
RawKeyGenerator kg = (RawKeyGenerator)KeyGenerator.getInstance("AES","Cryptix");
kg.initialize(rnd, 32);
key = kg.generateKey();
But I now get the following exception.
Unexpected exception in IJCE_SecuritySupport.registerTargets()
Please report this as a bug to <[email protected]>, including
any other messages displayed on the console, and a description of what appeared to cause the error.

at java.lang.Thread.run(Thread.java:536)
The KeyManager error at line 96 mentioned above is in my code and is related to the snipit of code mentioned above.
I need 1.4 as I need to use the new 1.4 plug-in on the clients to unencrypt the data.
I have not sent an email to the address mentioned above as I assume it is a migration problem.
I also had a message saying:
Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead.
I cannot do this as I need the java 1.4 plug-in for something else on the client. If I compile with 1.3 and run with 1.4 there seems to be an incompatibility problem.
I would be grateful for any advice as I need to ship this soon.
Thanks Andrew Mercer.

Hi!
I was trying to run some examples from the JXTA platform with jdk_1.3 (the classic HelloWorld), and got a very similar exception. The problem is I'm quite a newbie with JXTA and have no idea whatsoever about security in java, so I don't know what to do about it. I got the same messages about migrate the security model and report the whole thing as a bug, and I actually tried to send the message, but the address doesn't exist, so I'm stuck. If you've come across a solution or someone who might help, I would really like to know it! I copy below the text for the exception, in case it's helpfull to you somehow.
Kind regards,
Marta
