Yesterday I missed to write to the mailing list, so Romain answered me also directly. I think its ok that I publish his answer :-D

So thank you for your help Romain!

Before we don't support it AFAIK, we support CDI integration but not
EJB one. Could be added but @Inject should work for EJB once a
beans.xml added

Hello TomEE-Comunity,

could someone give me an explanation why it is possible to inject by @Inject
but not by @EJB in a MBean?

@javax.management.MBean
@ApplicationScoped
class MyMBean  {
         @Inject MyService myserviceA;
         @EJB    MyService myserviceB;

         @ManagedOperation
         public void test() {
                 System.out.println(myserviceA); // prints the proxy
                 System.out.println(myserviceB); // prints null
         }
}

@Stateless class MyService {}

My background is that I can use @Inject as long as my Stateless does not
implements an interface:

@Stateless class MyService implements MyInterface {}

Maybe my understanding of CDI is here not deep enough, but for now I use
normally @EJB e.g. if the EJB's implements an interface because with @Inject
the EJB can not be resolved anymore.

So for now I can not use the MyService with an interface in a MBean. Does
someone has a tip what I am doing wrong?
