This project provides a lightweight framework to serialize/deserialize (or marshall/unmarshall) java objects into XML. The implementation is based on standard SAX (Simple Api for Xml) but it follows a original approach based on the strong data encapsulation paradigm of Object Oriented (OO) programming.

The newest version!
