What is the ObjectFactory role during JAXB-Unmarshalling?

Question

I\'m using JAXB 2.2.2 to parse a simple XML-REST stream. This is the piece of code:

JAXBContext jc = JAXBContext.newInstance( \"com.example.entities\" );
Unm         


        

Answer 1

The ObjectFactory class generated by the XJC compiler is not useful to the factoryClass and factoryMethod @XmlType annotation because the factoryMethod must be a static no-arg method and the XJC generate instance methods.

Answer 2

You can leverage the @XmlType annotation to control how the objects are created:

@XmlType(factoryClass=ObjectFactory.class, factoryMethod="createRsp")
public class Response {
}
