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

"Now the question is: why the hack do we need that? Just use an @Singleton EJB if you like to share state between different WAR files, MDB and stuff!"

The problem with this is that this only works for EE applications. So if you want a singleton bean, you have to use @javax.ejb.Singleton for EE apps, and @ApplicationScoped for non EE apps, which I don't think is that great.

> 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.
