JAXB and Inheritance - Using XmlAdapter

In previous posts I have covered how to map inheritance relationships in JAXB. This can be done by element name (via @XmlElementRef), by the xsi:type attribute, or in EclipseLink MOXy using another XML attribute (via @XmlDescriminatorNode/@XmlDescriminatorValue).  In this post the type indicator will be an XML attribute/element unique to that type, and we will leverage an XmlAdapter to implement this behaviour.

How Does JAXB Compare to XMLBeans?

In previous posts I compared JAXB (JSR-222) to Simple and XStream when starting from Java objects.  In this post I'll compare JAXB to XMLBeans when starting from an XML schema.   I will use XMLBeans 2.5.0 (December 2009) which is the latest release.
