Can/Should I list inherited properties for a JAXB mapped bean in the "propOrder" annotation?

I have a bunch of JAXB annotated classes that have a field in common, so I moved that field to a super class, like this

public class Base {
    protected SomeType commonField;
}

@XmlRootElement(name = "foo") @XmlType(propOrder = { "commonField", "fooField" })
public class Foo extends Base {
    private SomeOtherType fooField;
}

@XmlRootElemen开发者_JAVA百科t(name = "bar") @XmlType(propOrder = { "commonField", "barField" })
public class Bar extends Base {
    private SomeOtherType barField;
}

Now whenever I marshall one of Foo or Bar I get an IllegalAnnotationException complaining about commonField being listed in propOrder but not present in the class. Removing it from the propOrder annotation everything works fine, but I thougt I was supposed to list all of the mapped fields. What am I missing?

The fields/properties from the inherited class will always appear before the fields/properties on the child classes. This means that by default you can not specify them in the propOrder on the child type. If however you mark the parent class as @XmlTransient the fields/properties will be treated as belonging to the child classes and can be included in the propOrder.
