[cdi-dev] [JBoss JIRA] (CDI-129) Clarify behaviour of @ApplicationScoped in EARs

Wed Oct 24 06:01:03 EDT 2012

    [ https://issues.jboss.org/browse/CDI-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12728802#comment-12728802 ] 

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

@Alternative is pretty much broken in Weld. I'd rather make the 'User' class in the shared lib an interface and test that. But pretty busy today. Feel free to fork and extend the tests. In any case that what this example shows gets pretty heavily used in the wild - most CDI based multi tenant apps work that way.

> 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.
