Help using cxfbean to return class as json

[Edward Mostrom]

Can't figure out how to return a custom class as a json string.  Here is
what I was trying but when I hit:
http://localhost:8080/example/person/4
I get:

No message body writer has been found for response class Person.

class Person {
  Integer id
  String name
}

@Path("/example")
class MyExampleResource{

  @GET
  @Produces("application/json")
  @Path("person/{id}")
  public Person getPerson(@PathParam("id") Integer id){
    Person p = new Person()
    p.id = id
    p.name = "Bob"
    return p
  }
}


CamelContext cxt = new DefaultCamelContext()
cxt.registry = new SimpleRegistry()
cxt.registry.registry.put("myResources", [new MyExampleResource()])
cxt.registry.registry.put("jsonProvider", new
org.apache.cxf.jaxrs.provider.JSONProvider())

cxt.addRoutes(new RouteBuilder(){
  void configure(){
    from("jetty:http://localhost:8080?matchOnUriPrefix=true";)
    .to("cxfbean:myResources?providers=#jsonProvider")
  }
})

cxt.start()
