How to create a JAX-RS service where the @Path sub-resource does not have a leading slash

I created the JAX-RS service (MyService), which has a number of additional resources, each of which is a subclass of MySubResource. The selected auxiliary resource class is selected based on the parameters specified in the MyService path, for example:

@Path("/") @Provides({"text/html", "text/xml"}) 
public class MyResource {
  @Path("people/{id}") public MySubResource getPeople(@PathParam("id") String id) {
    return new MyPeopleSubResource(id);
  }
  @Path("places/{id}") public MySubResource getPlaces(@PathParam("id") String id) {
    return new MyPlacesSubResource(id);
  }
}

where MyPlacesSubResource and MyPeopleSubResource are subclasses of MySubResource.

MySubResource is defined as:

public abstract class MySubResource {
  protected abstract Results getResults();

  @GET public Results get() { return getResults(); }

  @GET @Path("xml") 
  public Response getXml() {
    return Response.ok(getResults(), MediaType.TEXT_XML_TYPE).build();  
  }

  @GET @Path("html") 
  public Response getHtml() {
    return Response.ok(getResults(), MediaType.TEXT_HTML_TYPE).build();  
  }
}

Results are processed by the corresponding MessageBodyWriters, depending on the type of response image.

While this works, it leads to paths like / people / Bob / html or / people / Bob / xml, where what I really want is /people/Bob.html or / people / Bob.xml

Does anyone know how to accomplish what I want to do?
