Getting injection point from Bean#create
by arjan tijms
Hi,
In a producer method it's trivial to get access to an InjectionPoint
instance representing the point where the value produced by the
producer will be injected.
When registering a Bean manually from an extension using
AfterBeanDiscovery#addBean, this is not immediately obvious.
After some fumbling with the CDI APIs I came up with the following
code that seems to work on both Weld and OWB (didn't test CanDI yet).
It uses a small "dummy" class, which is used to grab an InjectionPoint off:
In a Bean:
public Object create(CreationalContext<Object> creationalContext) {
InjectionPoint injectionPoint = (InjectionPoint)
beanManager.getInjectableReference(
resolve(beanManager,
InjectionPointGenerator.class).getInjectionPoints().iterator().next(),
creationalContext
);
With InjectionPointGenerator being the following class:
public class InjectionPointGenerator {
@Inject
private InjectionPoint injectionPoint;
}
And resolve being the following method:
public static <T> Bean<T> resolve(BeanManager beanManager, Class<T> beanClass) {
Set<Bean<?>> beans = beanManager.getBeans(beanClass);
for (Bean<?> bean : beans) {
if (bean.getBeanClass() == beanClass) {
return (Bean<T>)
beanManager.resolve(Collections.<Bean<?>>singleton(bean));
}
}
return (Bean<T>) beanManager.resolve(beans);
}
As mentioned, while this seems to work, I wonder if it's the best approach.
Kind regards,
Arjan

Feedback of CDI F2F
by Antoine Sabot-Durand
Hi all,
We had a great time in Paris last week in our Face to Face meeting.
First I'd like to thank all the participant who brought their ideas,
experience and knowledge to this nice meeting:
- Martin Kouba (Mr Weld)
- Tomas Remes (Mr TCK)
- Antonio Goncalves (Mr Java EE)
- Emily Jiang (Ms Liberty Profile)
- Yann Blazart (Mr End user on OpenWebBeans)
And as a guest star: Emmanuel Bernard (Mr Third Party Spec)
I initially wanted to share the feedback here, but it's too long, so I'm
preparing a blog post on the website. It'll be published tonight or
tomorrow morning.

Hi guys,
So the meeting is starting friday in Paris. So far beyond the Red Hat guys
I have only 2 or 3 participants:
- Antonio
- Emily
- Werner (maybe)
Did I forget someone ?

[JBoss JIRA] (CDI-383) Clarify that session context is also destroyed at shutdown/undeploy
by Antonio Goncalves (JIRA)
[ https://issues.jboss.org/browse/CDI-383?page=com.atlassian.jira.plugin.sy... ]
Antonio Goncalves commented on CDI-383:
---------------------------------------
In Servlet 3.1 spec §11.3.4 Notifications At Shutdown
{quote}
On application shutdown, listeners are notified in reverse order to their declarations with notifications to session listeners preceding notifications to context listeners. Session listeners must be notified of session invalidations prior to context listeners being notified of application shutdown.

[JBoss JIRA] (CDI-497) session scope doesn't follow session lifecycle
by Antonio Goncalves (JIRA)
[ https://issues.jboss.org/browse/CDI-497?page=com.atlassian.jira.plugin.sy... ]
Antonio Goncalves commented on CDI-497:
---------------------------------------
In Servlet 3.1 §7.5 it's written :
{quote}
The session invalidation will not take effect until all servlets using that session have exited the service method

> ATM session destroyed event is bound to the request. this means a logout will not be able to access the right session when destroyed since most of the time logout = session destruction and then you can recreate a session (login case).
> Would be great to align CDI scopes - and then events - to the real lifecycle of the underlying observed event.

Re: [cdi-dev] Opening CDI F2F meeting to the community
by Werner Keil
Guys,
Only getting this digest now, but wanted to reply in any case. Sorry, I
could not make it this time. Primarily due to more travel coming up, as
DevoXX BE in Antwerp also invited me and 2 JSR 363 EG members to talk.
A significant number of EG members, especially those in Paris or France are
likely to go there, if they're not already at JavaOne (I should be at the
EC F2F and JavaOne, as long as PMO approves the travel request to go there
and tickets are still available ;-) thus I will meet almost all of those in
Paris now at either of these occasions or both.
Enjoy the stay and see you soon,
Werner

> Today if a user want to deactivate an observer at deployment time, she needs to observes {{ProcessAnnotatedType}} with {{(a)WithAnnotation(Observes.class)}} and replace the annotatedType by a new one without the {{@Observes}} annotation. It's quite heavy to manage.
> We could add a {{veto()}} method in {{ProcessObserverMethod}} to do this in a far easier and intuitive way.

[JBoss JIRA] (CDI-526) Include filters
by Martin Kouba (JIRA)
[ https://issues.jboss.org/browse/CDI-526?page=com.atlassian.jira.plugin.sy... ]
Martin Kouba updated CDI-526:

> CDI has support for exclude filters in the beans.xml where a certain part of a bean archive (no matter whether "annotated" or "all" type) can be excluded from CDI processing on a package level, e.g:
> {code:XML}
> <exclude name="com.acme.rest.*" />
> {code}
> With the rise of fat jars and CDI support for SE it would also be useful to be able to define an include filter. Suppose we have a single large jar file with all its dependencies shaded in. This jar file has the beans.xml file which means that all the packages in that file are processed (all classes are at least scanned for bean defining annotations or even turned into CDI beans in "all" mode). We can obviously add a couple of exclude filters for each of the libraries we do not want to scan. It would however be much nicer if we could define a single include filter e.g.:
> {code:XML}
> <include name="my.application.*" />
> {code}
> Other packages (that belong to shaded-in libraries) in the same jar would not be scanned at all.

Martin Kouba commented on CDI-526:
----------------------------------
We can make use of Weld non-portable feature:
bq. If both include filters and excludes filters are specified, only class names which match at least one include filter and don't match any exclude filter are scanned.
