Pete Muir commented on CDI-129:
-------------------------------
Bill Shannon points out that we also need to consider visibility of the bean when
clarifying this. For example, if you have the same bean class specified in two separate
wars, both of which are application scoped, you can't share the state between the two
(as you would get a CCE).
In fact, this makes me wonder if there isn't an "obvious" solution staring
us in the face? If we clarify that @ApplicationScoped means "shared across the
ear" and also that the same bean class packaged in two locations which are not
visible to one another (e.g. warA and war B) and cannot share state. Now we provide both
options of ear scoped state and war scoped state, and the state is only shared if the bean
class is packaged in a shared library or shared module (e.g. ejb module).
This seems like a good solution:
a) it means we don't need to proliferate the number of "application scoped"
annotations
b) it makes logical sense (if a user wants per-war state, package the bean in a war, if
the user wants shared-ear state, then package it as a shared lib).
WDYT?
introduce @EnterpriseScoped (or similar)

Key: CDI-129
URL:
https://issues.jboss.org/browse/CDI-129
Project: CDI Specification Issues
Issue Type: Feature Request
Components: Contexts
Affects Versions: 1.0
Reporter: Mark Struberg
Fix For: 1.1 (Proposed)
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.
