Jersey: How to introduce EJB into an additional resource?

Question

I would like to add the buisiness bean service to an additional resource, which is defined in the allocated class and delivered by the auxiliary resources locator.

Code example:

• Root resource

  @RequestScoped
  @Path("service")
  public class MyResource {
  
      @Context
      ResourceContext resourceContext;
  
      // Sub resource locator
      @Path("subservice")
      public MySubResource locateToSubResource () {
          // I don't want to create it myself.
          return resourceContext.getResource(MySubResource.class);
      }
  }
  

• Corresponding resource

  @RequestScoped
  public class MySubResource {
  
      // Note that businessBean itself consists of
      // multiple ejbs that also need to be injected so that it can do its job!
      @Inject
      private BusinessBean businessBean; 
  
      @GET
      @Produces(MediaType.TEXT_PLAIN)
      public String get () {
          return businessBean.doStuff();
      }
  }
  

Jersey will not have CDI to cause dependencies ... Note that resources are managed objects. Otherwise, it would even be impossible to insert a bean in the root resource ( here I push the number of views of my other questions to get more opinions ;-) )

I tried everything I could, but it just won't work ...

I am currently using libraries that come with glass fish 4.

And, of course, thank you in advance (almost forgot)!

    return CDI.current().select(SubResource.class).get();
}
