Help with XML Encryption

I'm sure this is a repeat question, but I can only see two weeks of this list.

Please help:
Using Apache XML Security I can sucessfully create and verify a signature, but 
I don't have sample code for encrypting (and decrypting) with the lib.  Can 
anybody give me some sample code, please?  Any code will do, even without any 
comments.

Thank you,
Daniel
