[cdi-dev] [JBoss JIRA] Commented: (CDI-129) introduce @EnterpriseScoped (or similar)

[Mark Struberg (JIRA)]

    [ https://issues.jboss.org/browse/CDI-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602349#comment-12602349 ] 

Mark Struberg commented on CDI-129:
-----------------------------------

I checked the spec again, and the terminus technicus 'application' is used for all kinds of 'applcations'. 
A few examples:

> An application that takes advantage of these services may be designed to execute in either the 
> Java EE environment or the Java SE environment. 

6.7.3:
> during the service() method of any servlet in the web application

also 6.7.3
> The application context is destroyed when the application is shut down.
There is a well defined webapp shutdown but nothing like that in the whole EE spec for EARs! Each EE Server has an own internal API for such things afaik.

also 
> The application context is shared between all servlet requests, web service invocations, EJB remote
> method invocations, EJB asynchronous method invocations, EJB timeouts and message deliveries to
> message-driven beans that *execute within the same application*.

The important part here is *execute within the same application* 
This part would not be needed if this would work across all the EAR anyway, isn't?


This is a pretty hairy area and I see that it's not so 100% clear. We should think really hard about how this is going to be used in real world projects.

> 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.
