padding error
Hi,
I'm hoping someone can help me with this error.
I get the following output and error when trying to run the sample
Encrypter.java:
Data: AES
Key encryption key stored in file: c:/SampleCode/XMLencrypt/testXMLenc/kek
javax.crypto.spec.SecretKeySpec@141349b0

I found this thread:
http://mail-archives.apache.org/mod_mbox/xml-security-dev/200406.mbox/%3c24761.1086951999@www38.gmx.net%3e
But none of that helped. It didn't seem to help the other guy either as
there is another thread 10 days later where he still talks about the
problem. His email is now defunct so I can't ask him how he eventually
solved it or if he did.
Any ideas?
I've got the bouncy castle provider jar in <java_home>\lib\endorsed.
That location is also in my classpath.
Also, I get the following output from the following code:
------output----------
Cipher provider: SunJCE version 1.42

Security.addProvider(new
org.bouncycastle.jce.provider.BouncyCastleProvider());
try {
Cipher cipher = Cipher.getInstance("DES");
System.out.println("Cipher provider: "

System.out.println("Cipher algorithm: "
+ cipher.getAlgorithm());
}
catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
catch (NoSuchPaddingException e) {
e.printStackTrace();
}
}

By the way, it's the same error when I put it as number one.
If I use another app to list the providers it finds the BC provider fine.
I removed the explicit "BC" from the getInstance calls.
Now I get this error:

It's a bug in JDK 1.4.2. If a Cipher implementation doesn't support a
particular padding scheme, it doesn't fallback and check the remaining
providers. If you upgrade to 1.5 (5.0), the problem will go away.

Last question...
I fixed the problem. The last issue was also my fault. I had changed the
algorithm to DES when I was troubleshooting and for some reason it doesn't
like algorithms under 128 bit. But I don't know why it didn't work
previously.
Why couldn't it find the provider at number 6?
I'm new to java encryption so I'll figure out how why it didn't like DES
vice triple DES.
I just don't know why the providers didn't cascade.
Thanks for the assistance.

Ok, one more update. The last error was entirely my fault.
I was searching for an element that didn't exist.
But I'm still getting errors.
Current configuration:
BC provider at number 2.
searching for text1 element.
Still using j2se 1.4.2
This is the latest output and error:

Ok, I placed the BC provider at number 2 and now I get this error:

Note that it says I don't have a handler installed for URI BC.
I have the provider in both <javaHome>\lib\ext and <javaHome>\lib\endorsed.
Both locations are in my classpath.
But that did cause a change. I'm downloading j2se 5.0 and maybe that will
solve everything. I'd still like assistance with this issue just in case
5.0 is not the fix.
Thanks.

From the stack trace, it seems like you are picking up Sun's JCE
implementation, and not BouncyCastles. Are you using JDK 1.4? Sun's JCE
implementation in 1.4 does not support the ISO10126Padding scheme. You
need to upgrade to at least JDK 1.5 if you want to use Sun's JCE provider.
Otherwise, it should fallback and still find BC's provider, but it
doesn't seem to be doing that. Try putting BC's provider preference
higher in the java.security file (before Sun's provider).

Did you add an entry like the following to the
