Mark Struberg commented on CDI-129:
-----------------------------------
What you say is that the Servlet would operate on a
different instance of the same R bean than the MailService?
No of course not! At least not in my model, but in your approach this exact problem would
happen!
In my model a call stack would ALWAYS get the same contextual instance for the same
injection points! Dude there are serious understanding problems we should clarify it
seems. Go back a few meters and take a look at it again. We could also again do some tele
conference together with pete to clarify the behaviour. You can also take a look at OWB
where this perfectly works.
And PLEASE do avoid the term 'bean'. I like to NEVER read BEAN in this thread
again, pretty please! It's sooooo ambiguous! Please erase it from your mind :)
What happens in my scenario is that the same shared class T could resolve to different
Bean<T> depending on the webapp. But as each webapp has it's own contextual
instances the same code @Inject T t; might end up as T1 in webapp1 and T2 in webapp2. This
is not a problem - not even in CDI 1.0 - as the two webapps would get different contextual
instances and always see the whole classes of all it's own webapp!.
Clarify behaviour of @ApplicationScoped in EARs

Key: CDI-129
URL:
https://issues.jboss.org/browse/CDI-129
Project: CDI Specification Issues
Issue Type: Clarification
Components: Contexts
Affects Versions: 1.0
Reporter: Mark Struberg
Assignee: Pete Muir
Fix For: 1.1 (Proposed)
Since @ApplicationScoped currently is defined in 6.5.2 as to be 'like in the Servlet
specification' this means that you will get a new instance for every WebApplication
(WAR file).
There is currently no specified CDI scope for providing a single shared instance for a
whole EAR.
We could (ab-)use @Singleton for that, but this is currently not well defined at all.
Alternatively we could introduce an own new annotation like @EnterpriseScoped or likes.
