Moxy can't unmarshal subclass field which overide supperclass

Question

When use the Moxy to unmarshaling the sample xml to child, it always can't get the name. It always is null.

Sample xml

<?xml version="1.0" encoding="UTF-8"?>
<child>
    <name value="test"/>
</child>

Sample class

public class Parent {

    private String name;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

@XmlRootElement
public class Child extends Parent {

    @Override
    @XmlPath("name/@value")
    public String getName() {
        return super.getName() == null ? "" : super.getName();
    }

    @Override
    public void setName(String name) {
        super.setName(name);
    }
}


JAXBContext jc2 = JAXBContext.newInstance(Child.class);
Unmarshaller unmarshaller = jc2.createUnmarshaller();
Child child = (Child) unmarshaller.unmarshal(new File("d:\\sample.xml"));

How can I get this value, if I can't make any change on the Parent class.

Thanks,

After dig with http://blog.bdoughan.com and stackoverflow.

OK, I finally found these on stackoverflow

<?xml version="1.0"?>
<xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
    version="2.6.0">
    <java-types>
        <java-type name="com.abc.Parent" xml-transient="true" />
    </java-types>
</xml-bindings>

With Code

    Map<String, Source> metadata = new HashMap<String,Source>();
    metadata.put("com.abc", new StreamSource( Volume.class.getClassLoader().getResourceAsStream("sample.xml"))); 
    Map<String,Object> properties = new HashMap<String,Object>();
    properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, metadata);
    JAXBContext jc2 = JAXBContext.newInstance(new Class[] {Child.class}, properties);

Then could get/set the value in superclass.

If you use the maven this article may help you for the xmlbinding file location.

How do I solve EclipseLink's (MOXy) 'getting property "eclipselink.oxm.metadata-source" is not supported'?
