CDI Events not received from a Singleton EJB

I'm struggling a little on CDI Events. I have a class that is implemented as a CDI Singleton almost like this:

import import javax.inject.Singleton;

@Singleton
public class MyClass{

    @Inject
Event<StatusUpdateEvent> events;

    public MyClass(){};

    public void myMethod(){
        events.fire(new StatusUpdateEvent());
    }
}

Then I have my consumer class implemented as EJB Singleton

import javax.ejb.Singleton;

@Singleton
public class MyObserver(){

    public MyObserver(){};

    public onStatusUpdateEvent(@Observes StatusUpdateEvent event){

        ...do something...

    }
}

The problem is that when myMethod is invoked no events is received from myObserver. MyClass is included in a library jar of my EAR project (the jar has beans.xml) and MyObserver is an EJB of the same EAR.

What am I doing wrong? Thanks a lot for your help!

CDI injection does not work across class-loader boundaries. Since your project is an EAR, the ejb-jar is most likely on a separate class-loader. For example, if your project structure is:

--EAR
  |--EAR/lib
  |--|--EAR/lib/CDIBeans.jar
  |--EJBArchive.jar

then any beans from CDIBean.jar won't be available for injection into your EJBArchive.jar.
