Hi Samuel Ni,
i do not see the attached code. However, you might want to try
to modify the json-from-jaxb example a bit, to see how the thing works:
at com.sun.jersey.samples.jsonfromjaxb.jaxb.Flights class, modify the @XmlRootElement annotation to (line 79) put an explicit namespace there:
@XmlRootElement(name = "flights", namespace="
http://jersey.dev.java.net")
at com.sun.jersey.samples.jsonfromjaxb.config.JAXBContextResolver class,
modify the creation of the conext (line 68), with:
this.context = new JSONJAXBContext(JSONConfiguration.mappedJettison().xml2JsonNs(new HashMap<String,String>(){{put("
http://jersey.dev.java.net", "jersey");}}).build(), cTypes);
now run the app and try to:
% curl -Haccept:application/json -i
http://localhost:9998/jsonfromjaxb/flights
HTTP/1.1 200 OK
server: grizzly/1.9.8
Content-Type: application/json
Transfer-Encoding: chunked

{"jersey.flights":{"flight":[{"flightId":"OK123","company":"Czech Airlines","number":123,"aircraft":"B737"},{"flightId":"OK124","company":"Czech Airlines","number":124,"aircraft":"AB115"}]}}
You can see the "jersey.flights" JSON name incorporates the mapped namespace.
I suspect your JAXBContexResolver#getContext method does not return
the right JSONJAXBContext instance,
or you are missing the @Provider annotation there, or something else
is going wrong, which is really hard to tell without access to the whole codebase
of your app.
HTH,
~Jakub
