Thanks Jeff.

How would this work in the below case?

  @Path("/customers")
  public class CustomersResource {
    @Context
    UriInfo uriInfo;
    @Context
    Request request;

    public CustomersResource(UriInfo uriInfo, Request request) {
      this.uriInfo = uriInfo;
      this.request = request;
    }

    @Path("/add")
    public CustomerResource getCustomerResource() {
      return new CustomerResource(uriInfo, request);
    }
  }

  public class CustomerResource {
    @Context
    UriInfo uriInfo;
    @Context
    Request request;

    public CustomerResource(UriInfo uriInfo, Request request) {
      this.uriInfo = uriInfo;
      this.request = request;
    }

    @POST
    @Consumes("application/xml")
    @Produces("application/xml")
    public Response addCustomer(Customer customer) {
      URI uri = uriInfo.getAbsolutePath();
            //how to generate the new URI with id?
      customer.setId(1234);
      Response r = Response.created(uri).build();
      customer.setUri(uri.toString());
      return r;
    }
  }

How would I create the new URI with customer Id?

Thanks!
