Reflex framework can transform any JDO to JSON/XML and back with a simple interface. It depends on XStream(xstream-1.1.2.jar) , xpp3(xpp3-1.1.3.4-RC8.jar) and org.json(json-20070829.jar).

The reflexworks provides a library and source code that make it easy to develop applications that provide feed data in JSON format and in XML formats.
