The example is available at http://mediacast.sun.com/share/japod/JsonFromJaxb.zip

I have bundled all necessary jar files, so everything you need to run the example
is to unzip the archive, cd to JsonFromJaxb and run

% ant dist

It will produce dist/JsonFromJaxb.war, which you can deploy to your favorite Java web container.
My favorite container is GlassFish, so I would continue with

% $AS_HOME/bin/asadmin deploy dist/JsonFromJaxb.war

The flights resource should be then available at something like
http://localhost:8080/JsonFromJaxb/flights
depending on your web container configuration.

Please see how it works for me at the following screenshot:

If you want (i.e. you set Accept HTTP header to "application/xml")
to get XML representation, you will GET this:

<flights>

  <flight flightId="OK123">

    <company>Czech Airlines</company>

    <number>123</number>

    <aircraft>B737</aircraft>

  </flight>

  <flight flightId="OK124">

    <company>Czech Airlines</company>

    <number>124</number>

    <aircraft>AB115</aircraft>

  </flight>

</flights>

If you want JSON, the following is what you will GET:

{"flights":{"flight":

[{"@flightId":"OK123","company":{"$":"Czech Airlines"},"number":{"$":"123"},"aircraft":{"$":"B737"}},

{"@flightId":"OK124","company":{"$":"Czech Airlines"},"number":{"$":"124"},"aircraft":{"$":"AB115"}}]}}

The example contains Netbeans project files,
so you might want to open it in the NB IDE. If you want to see the most important
part of the source code, just look at src/java/com/sun/ws/rest/samples/jsonfromjaxb/resources/FlightList.java.

You can see what is inside bellow. Please note, that you can not only GET the JSON representation,
but also PUT a new one.

@UriTemplate(value = "/flights/")

public class FlightList {



    static Flights myFlights;

    public FlightList() {

    }


    @HttpMethod(value = "GET")

    @ProduceMime({"application/json", "application/xml"})

    public Flights getFlightList() {

        return getFlights();

    }


    @HttpMethod(value = "PUT")

    @ConsumeMime({"application/json", "application/xml"})

    public Response putFlightListAsJson(Flights flights) {

        Response.Builder rBuilder = Response.Builder.noContent();

        setFlights(flights);

        return rBuilder.build();

    }


    private synchronized void setFlights(Flights flights) {

        myFlights = flights;

    }


    private synchronized Flights getFlights() {

        if (null == myFlights) {

            myFlights = (new ObjectFactory()).createFlights();

            FlightType fligth123 = new FlightType();

            fligth123.setCompany("Czech Airlines");

            fligth123.setNumber(123);

            fligth123.setFlightId("OK123");

            fligth123.setAircraft("B737");

            FlightType fligth124 = new FlightType();

            fligth124.setCompany("Czech Airlines");

            fligth124.setNumber(124);

            fligth124.setFlightId("OK124");

            fligth124.setAircraft("AB115");

            myFlights.getFlight().add(fligth123);

            myFlights.getFlight().add(fligth124);

        }

        return myFlights;

    }

}
