Hm, maybe I'm misunderstanding the purpose of the mapping file. I simply want to map from an XML file containing data into a Java object representation of that data. The Castor mapping XML file seems like the most logical way to do this without having to write a Java XML parser. The XSD merely provides requirements on how the XML file should be formed.
I simply followed the guide at http://www.castor.org/how-to-enable-xml-validation.html to get my XML file validated against the XSD, but I'm having the issues I previously mentioned. What are you talking about when you mention "internal descriptor classes"? I looked over your website, and it primarily talks about the mapping file, so I'm a little confused. I don't see any mention of "internal descriptor classes." Thanks for your help.
