Actually your best bet is to write a custom ContextResolver Provider like the following that uses natural building of JSON.

   @Provider
   public class YourContextResolver implements ContextResolver {

    private JAXBContext context;
    private Class[] types = { YourSpecialBean.class };

    public YourContextResolver() throws Exception {
        this.context = new JSONJAXBContext(
                JSONConfiguration.natural().build(), types);
    }

    public JAXBContext getContext(Class objectType) {
        for (int i = 0; i < this.types.length; i++)
            if (this.types[i].equals(objectType)) return context;

        return null;
    }
}

The only thing special here to notice is the YourSpecialBean.class in the Class[]. This defines an array of class types that this provider will resolve naturally.
