Okay, I've seen the recent OWB (or CDI) topics, so I thought I might
introduce a separate thread based on my experience today.
Months ago, I migrated from JSF managed beans to CDI manageds (and migrated
from Glassfish to TomEE/OpenWebBeans), two birds with one stone. During
that migration, I created the following for descendant managed beans in my
app.
@Qualifier
@Retention(RUNTIME)
@Target({TYPE, METHOD, FIELD, PARAMETER})
public @interface Descendant {}
which allowed me to implement the following ancestor class (for example):
@Default
@Named("pf_addressController")
@SessionScoped
public class pf_AddressController implements Serializable {
and develop descendants, which extend the ancestor as follows (for example):
@Descendant
@Named("pf_hotelAddressController")
@SessionScoped
public class pf_HotelAddressController extends pf_AddressController {
also, I was able to add the following to one of my pf_OrdersController
(which has 'no' descendant classes)
@Inject @Descendant
private pf_OrderCustomerPointOfContactController
orderCustomerPointOfContactController;
Everything mentioned above has worked in production ever since I started
using TomEE (almost 6 months ago).
Today, it was suggested that I use @Typed instead of this user-defined
@Descendant. @Typed seems to work well on/for extending managed bean
ancestors, but I replaced @Descendant (in the code above) with @Typed as
seen below (for bean 'member'):
@Inject @Descendant
private pf_OrderCustomerPointOfContactController
orderCustomerPointOfContactController;
and now, TomEE will not start, because of the following error:
