How to enable CDI inject in web service (jaxrs/jersey) on java se running grizzly?

Question

How do I allow CDI injection of resources into restful web service resources? I am running on standard java using weld 2 (cdi), jersey (jaxrs), and grizzly (web server). Here is my simple web resource:

import training.student.StudentRepository;
import javax.inject.Inject;
import javax.ws.rs.*;

@Path("student")
public class StudentWebResource {
  @Inject
  private StudentRepository studentRepository;  

  @GET
  @Path("count")
  @Produces(MediaType.TEXT_PLAIN)
  public Integer getCount() {
    return studentRepository.studentCount();
  }
}

And here is how I've got weld starting my simple web server:

public class Main {
  public static void main(String[] args) throws Exception {
    startCdiApplication();
  }

  public static void startCdiApplication() throws Exception {
    Weld weld = new Weld();
    try {
      WeldContainer container = weld.initialize();
      Application application = container.instance().select(WebServer.class).get();
      application.run();
    } 
    finally {
      weld.shutdown();
    }
  }
}

And the code that I suspect will need to be modified to inform jersey to use weld for CDI inject resolution:

...
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;

public class WebServer implements Application {

  /*
   * startup the grizzly http server to make available the restful web services
   */
  private void startWebServer() throws IOException, InterruptedException {
    final ResourceConfig resourceConfig = new ResourceConfig().packages("training.webservice").register(new JacksonFeature());
    final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(getBaseUri(), resourceConfig);
    server.start();
    Thread.currentThread().join();
  }

  ...

  @Override
  public void run() throws IOException, InterruptedException {
    startWebServer();
  }
}

After seeing this stackoverflow post, I implemented the following solution. Not sure if it is the best route to take, but it worked.

I created an hk2 Binder and registered the Binder:

public class WebServiceBinder extends AbstractBinder {

  @Override
  protected void configure() {
    BeanManager bm = getBeanManager();
    bind(getBean(bm, StudentRepository.class))
        .to(StudentRepository.class);
  }

  private BeanManager getBeanManager() {
    // is there a better way to get the bean manager?
    return new Weld().getBeanManager();
  }

  private <T> T getBean(BeanManager bm, Class<T> clazz) {
    Bean<T> bean = (Bean<T>) bm.getBeans(clazz).iterator().next();
    CreationalContext<T> ctx = bm.createCreationalContext(bean);
    return (T) bm.getReference(bean, clazz, ctx); 
  }
}

Then modified the ResourceConfig instantiation from above to:

final ResourceConfig resourceConfig = new ResourceConfig()
    .packages("training.webservice")
    .register(new JacksonFeature())
    .register(new WebServiceBinder());
