I don't quite follow it.
I'm simply asking why the method which has already been generated and is
available on the ObjectFactory is ignored, what is the point of generating
such methods ?
I'm also asking when such ObjectFactory JAXBElement getters are being used ?
Consider a set of classes being generated from a schema, like the one Karen
provided. It's not always possible to go and add @XmlRootElement to every
generated class. So I thought that is where ObjectFactory would help, as
guess what, it already has all the JAXBElement getters generated.
So why is it that such a getter is not picked up ? I'm about to provide to
provide a generic JAXBElement wrapper facility anyway but I'd like to
understand why ObjectFactory is not being utilized
cheers, Sergey
