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

Tue Sep 24 07:04:46 EDT 2013

    [ https://issues.jboss.org/browse/CDI-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12806853#comment-12806853 ] 

Bauke Scholtz commented on CDI-129:
-----------------------------------

Dupont Dupont has a very valid question in #4. This is currently completely blocking the usage of JSF utility library OmniFaces in multiple WARs in the same EAR which is deployed to a Java EE 6 compatible container. See also https://code.google.com/p/omnifaces/issues/detail?id=251. 

I only wonder, isn't specifically this issue already fixed by https://issues.jboss.org/browse/WELD-1259? Haven't tried Weld 2 yet as JBoss AS 7 / EAP 6 can't be upgraded to use Weld 2.

> 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.
