Question

I need some help regarding the following issue with JAXB 2.1.

Answer 1

The EclipseLink JAXB (MOXy) implementation offers a means of representing the metadata as XML that you could use:

• http://wiki.eclipse.org/EclipseLink/Examples/MOXy/EclipseLink-OXM.XML

You can specify some of the metadata using annotations, and the rest as XML. Below is what your document would look like:

<xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm">

    <java-types>

        <java-type name="Person" xml-transient="true"/>

    </java-types>

</xml-bindings>

Answer 3

You can provide mappings for third-party classes using Annox.

Answer 4

OK, this was a pain in the you-know-what. Finally, after sifting through many a blog postings, here's what I did,

added a package-info.java class in the 'third-party class' package like this,

@javax.xml.bind.annotation.XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.NONE) package third-party-package;

In my case, it was just one package so it was easy. Obviously, you will have to do this for for every separate package structure. I haven't tried doing it at a master package level.

You can annotate your SuperPerson class with @XmlTransient, that will instruct JaxB not to automatically marshal all properties. And then annotate each getter (or field) you want to serialize with the relevant annotation.

This approach is not very elegant, but it should work
