Joda DateTime Format for XMLGregorianCalendar Type

Question

I'm using JAXB 2.2.8-b01 impl and I have a schema which has a xs:date element which creates a XMLGregorianCalendar instance. I'm trying to get a Joda-Time DateTime timestamp format but since I have to have a XMLGregorianCalendar instance, I'm not sure its possible. Any ideas?

Schema XSD:

<xs:element type="xs:date" name="date-archived" minOccurs="0" maxOccurs="1" nillable="false"/>

JAXB Generated Property:

@XmlSchemaType(name = "date")
protected XMLGregorianCalendar date;

XML Conversion Class:

//java.util.Date being passed


private XMLGregorianCalendar converToGregorianCal(Date date) {
    DatatypeFactory df = null;
    try {
        df = DatatypeFactory.newInstance();
    } catch (DatatypeConfigurationException e) {
        LOG.error("error getting DatatypeFactory instance " + e.getMessage()); 
    }
    if (date == null) {
        return null;
    } else {
        GregorianCalendar gc = new GregorianCalendar();
        gc.setTimeInMillis(date.getTime());
        return df.newXMLGregorianCalendar(gc);
    }
}

This is a short way:

public DateTime convert(final XMLGregorianCalendar xmlgc) {
    return new DateTime(xmlgc.toGregorianCalendar().getTime());
}
