Gerhard Petracek commented on OWB-652:
--------------------------------------
one bean-manager per ear and one per web-app (and the bean-manager/s of the
web-app/s can delegate to the bean-manager of the ear) is fine for me.
however, we have to ensure that the #getBeans methods return useful results.
> Introduce HierarchicBeanManager

> Key: OWB-652
> URL: https://issues.apache.org/jira/browse/OWB-652
> Project: OpenWebBeans
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1.3
> Reporter: Mark Struberg
> Assignee: Mark Struberg
> Fix For: 1.1.4
>
>
> The currently implemented BeanManager cannot properly deal with multiple
> ClassLoaders forming an isolation hierarchy.
> This mainly hits EAR deployment in Java EE servers. The spec is not really
> clear about this scenario and in fact no existing EE server currently solves
> this problem sattisfyingly.
> I already explained quite a few times how we can overcome this problem:
> http://mail-archives.apache.org/mod_mbox/openwebbeans-dev/201202.mbox/%[email protected]%3E
> GERONIMO-6005
> https://issues.jboss.org/browse/CDI-142
> https://issues.jboss.org/browse/CDI-18
> https://issues.jboss.org/browse/CDI-129
> The solution:
> Each ClassLoader which has a BeanArchive will get it's own Beans. Any Beans
> accessible through a parent BeanManager will not be contained. Instead they
> must be resolved via the parent ClassLoader.
> It should be possible to easily implement this by introducing a
> HierarchicScannerService as a child-Interface of ScannerService which knows
> how to exclude parent BDAs. If a HierarchicScannerService is configured, the
> BeanManager will automatically delegate the detection to it's parent
> BeanManager. Otherwise all remains the way it is right now.
