When Your DI Breaks: bean-discovery-mode in CDI 1.1 (JavaEE 7)

CDI 1.1 JSR-346 comes with finer scanning control and an attribute bean-discovery-mode with possible values: all, annotated and none:

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"

However, the suggested value "annotated" only recognizes annotated CDI managed beans. Beans without any annotation are ignored. The value all behaves like in Java EE 6: also beans without any annotations are recognized.

So if DI doesn't work (e.g. org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type…), double check the beans.xml.

If the cure is more XML, does it cross anybody's mind that the disease is XML?

I am using GF4 and created a class in application client jar and trying to inject it into EJB module and Web mobule. but i am getting below exception.

Hi Adam
Is it possible to @Inject String (having @Produces method defined elsewhere) while bean-discovery-mode is set to annotated???? Of course JavaEE7 and GF4.0.

It is surprising that CDI expert committee completely overlooked the necessity to manually register beans or specify beans.xml file from alternative locations, or specify jar-file paths in one beans.xml.

This would have reduced the need for a lot of boiler plate code to make classes outside the established JEE deployment structure available as CDI beans.

I hope at least JEE-8 fixes this shortcoming, and makes manual registration of CDI beans simpler.

Hi Adam,
ho can i define Alternatives across jars... by default the alternative only works for the beans in current jar. is there any annotation or some option in beans.xml.. (i m new to this thing). thanks
