ValidationEventHandler example:
JAXBContext jc = JAXBContext.newInstance("mypkg.schema.es.itecban.wsdl.datosfirma");
Unmarshaller u = jc.createUnmarshaller();
u.setEventHandler(new ValidationEventHandler() {
public boolean handleEvent(ValidationEvent event) {
System.out.println(event.getMessage());
return true;
}
});
