Can Moxy be used to transform an XML message from one version of an XSD to a newer version of an XSD? If it can, what are the basics of accomplishing this? The newer XSD has some new tag and prefix names and a few new fields. I briefly looked at Dozer to map between the two sets of JAXB classes and have also changed the DOM by parsing thru with XPATH commands, but there must be a better way.

Hi Steven,

Yes MOXy can be used to support mapping an object model to multiple versions of an XML schema by leveraging MOXy's external metadata.

Typical Approach

1. Map the object model to one version of the XML schema using annotations. Create a JAXBContext on this model.
2. Leverage MOXy's mapping document to override the mappings that have changed for the new version. Create another JAXBContext that leverages the annotations and mapping document.
3. You can apply multiple mapping documents so you could have one that represents the delta for each version.

If the document format changed a lot, then you can specify that the mapping document completely replaces any metadata supplied via annotations.
