Sorry, I had about five projects open in NetBeans when I recommended
that sample and I think I confused the Bookmarks and Storage examples.
What you need to do is to create a JAXB bean with @XmlRootElement on
the class. Write a JAX-RS bean with a method that returns the JAXB
bean and is annotated with @ProduceMime("application/json") something
like:
@XmlRootElement
public class States {
...
}
@UriTemplate("states")
public class StatesResource {
@HttpMethod
@ProduceMime("application/json")
States getStates() {
...
}
}
The JAXB provider will automagically convert the returned States
class instance into JSON for you. I'm sure Jakub's example will show
this in more detail.
