JAXB Unmarshall Created an Empty Object

Question

I am using JAXB to unmarshal an XML file into an object tree. The root object is non-null, but all of it's members are null even though there is data in the XML file. My object classes were generated with Axis2 from wsdls. I have the ObjectFactory class, the jaxb.index class, the package.info annotation, etc.

My problem is the same as this discussion: http://old.nabble.com/AXIS2,-JAXB---Unmarshalling-td26847419.html

First and foremost: is there a way I can get it to fill the data properly?

If not, is there a good substitute library for either Axis2 or JAXB that does the same thing but that will play nicely with each other?

Answer 1

JAXB by default silently ignores errors. I cannot see any reason why this is the default configuration. Try adding this code to throw an exception if something goes wrong.

unmarshaller.setEventHandler(
    new ValidationEventHandler() {
        @Override
        public boolean handleEvent(ValidationEvent event ) {
            throw new RuntimeException(event.getMessage(),
                                       event.getLinkedException());
        }
});
