JAXB/MOXy - Unmarshall values of child and nested children in a single class including support for element with the same name

Question

I'd like to unmarshall a xml file with nested children with same name to a single class. I tried everything I found but nothing work, the values of nested children remain null.

What is wrong ?

jaxb.properties

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

myFile.xml

<?xml version="1.0" encoding="UTF-8"?>
<clock>
  <name>myClock</name>
  <times>
    <starttime>09:00</starttime>
    <endtime>12:00</endtime>
    <starttime>13:00</starttime>
    <endtime>17:00</endtime>
  </times>
</clock>

Clock.java

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Clock {

    @XmlElement
    private String name;

    @XmlPath("times/starttime[1]/text()")
    private String amStartTime;

    @XmlPath("times/endtime[1]/text()")
    private String amEndTime;

    @XmlPath("times/starttime[2]/text()")
    private String pmStartTime;

    @XmlPath("times/endtime[2]/text()")
    private String pmEndTime;

}

Test code

File file = new File("myFile.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(Clock.class);

Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Clock clock = (Clock) jaxbUnmarshaller.unmarshal(file);

Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(clock, System.out);

Ouput

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<clock>
    <name>myClock</name>
</clock>

What do you get if you fully populate your object model and marshal it? Also if you call `.getClass()` on your `jaxbContext` what do you see as the real class? — bdoughan, Jul 10 '14 at 20:02
`` `` ` myClock` ` 1:00` ` 2:00` ` 3:00` ` 4:00` `` and `class com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl` — elfdev, Jul 10 '14 at 20:39
I finally found where was my mistake. My jaxb.properties was not read because it wasn't in the package of my domain class. Now it works perfectly ! — elfdev, Jul 10 '14 at 21:08
Can you add that as an answer? This will help people in the future who encounter this in the future and find your question. — bdoughan, Jul 10 '14 at 21:12

2 solutions found here : JAXBContext, jaxb.properties and moxy

I can either put the jaxb.properties in the package of Clock.java or get my JABXContext instance this way :

JAXBContext jaxbContext = JAXBContextFactory.createContext(new Class[] {Clock.class}, null);
