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). H

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 getBean(BeanManager bm, Class clazz) {
    Bean bean = (Bean) bm.getBeans(clazz).iterator().next();
    CreationalContext 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());
