According to your input XML, the only thing you need is your Appointment
class.
So unmarshal and marshal to this class.
You can then manually set your Request and Message in your own code such
as:
//-- setup Unmarshaller
Unmarshaller unmarshaller = new Unmarshaller(Apppointment.class);
unmarshaller.setMapping(...);
//-- read Appointment
Appointment app = unmarshaller.unmarshal(reader);
Request req = new Request();
req.setAppointment(app);
Message msg = new Message();
msg.setRequest(req);
Hope that helps.
