Setting (un)marshaller options for JAXB using CXF?

[jmdev <jh...@yahoo.com>]

I am looking to be able to add behaviors to some of my JAXB generated
classes.  The JAXB documentation seems to suggest that I need to set a
property on the (un)marshaller class 

(i.e.

Unmarshaller u = context.createUnmarshaller();
u.setProperty("com.sun.xml.bind.ObjectFactory",new ObjectFactoryEx());
PersonEx p = (PersonEx)u.unmarshal(new StringReader("<person />"));

)

Is it possible to get access to the (un)marshaller classes in the course of
CXF web service call so that I can set properties?  If so, could you provide
a quick example of the method call(s)?

Thanks!

I don't think there is access to the actual unmarshaller/marshallers.   
However, the JAXBDataBinding object itself has maps for properties that are 
then copied over into any marshaller/unmarshaller that it creates.    If you 
look on the page at:
http://cwiki.apache.org/CXF20DOC/jaxb.html
it shows some starting points for how to configure the JAXB databinding.   
Looking into the JAXBDataBinding class, there are fields for:
    private Map<String, Object> contextProperties;
    private Map<String, Object> marshallerProperties;
    private Map<String, Object> unmarshallerProperties;
    private Unmarshaller.Listener unmarshallerListener;
    private Marshaller.Listener marshallerListener;
    private ValidationEventHandler validationEventHandler;

so those would be some of the properties that you could configure to do 
whatever customization that you may need.
