REST + json + JAXB + namespaces

Question

I am trying to wrap my head in POSTing json in a REST service and JAXB namespace. I use Resteasy to tag the server side method. I have the following service:

@POST
@Mapped(namespaceMap={@XmlNsMap(namespace="http://acme.com", jsonName=""))
@Path("/search")
@Consumes("application/json")
public List<I> search(SearchCriteria crit);

I have the following objects:

@XmlRootElement(namespace="http://acme.com")
public class DateCriteria {
    @XmlElement
    private Date start;
    @XmlElement
    private Date end;
}


@XmlRootElement(namespace="http://acme.com")
public class MultCriteria {
    @XmlElementRefs({@XmlElementRef(type=DateCriteria.class)})
    private List<DateCriteria> dateCriterias;
}

I can send the following JSON in a message and it works:

{ "acme.MultCriteria": { "acme.DateCriteria": { startDate: "2009/01/01", endDate: "2009/01/01" } } }

In the service, I get a MultCriteria object with a single list of DateCriteria items. Oddly enough, I have to pass the namespace in the JSON object, even if I marked the map service with an empty namespace.

If I try to send an array as follows:

{ "acme.MultCriteria": { "acme.DateCriteria": [ { startDate: "2009/01/01", endDate: "2009/01/01" }, { startDate: "2009/01/01", endDate: "2009/01/01" } ] } }

I get a MultCriteria object with an empty DateCriteria list. If I modify the DateCriteria object so that it has an empty namespace, then the syntax above works fine.

JAXB, @XmlRootElement(namespace="http://acme.com"), . , .

@XmlRootElement(namespace="http://acme.com")
public class MultCriteria {
