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

Mon Oct 22 18:48:01 EDT 2012

    [ https://issues.jboss.org/browse/CDI-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12728482#comment-12728482 ] 

Stuart Douglas commented on CDI-129:
------------------------------------

Note that this approach actually solves some other problems as well, such as what happens when an extension in a war modifies a shared bean? At the moment this change will be visible everywhere, which violates the 'wars are isolated' principle. If you set the war to be an isolated deployment then this will not longer be an issue, as the war will only modify its own copy of the bean.

> 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.
