I am trying to inject a @Stateless EJB into my EntityListner. The @PrePresist method of my EntityListener is invoked, but the injected EJB resolves to null so a NullPointerException is thrown.
public class MyEntityListener {
@Inject
private MyService myService; // @Stateless EJB
@PrePersist
public void prePersist(MyEntity entity) {
final Foo foo = myService.getFoo(); // !! NPE thrown here!!
entity.setFoo(foo);
}
}
Previous questions which I found here on SO are dealing with the problem, that JPA does provide CDI only from JPA 2.1 on but not for JPA 2.0, but I am using JPA 2.1. So what else may be the problem here?

Injection of my EJB into other session beans works fine, both with EJB inection (@EJB) as well as CDI injection (@Inject). It only fails in the EntityListner.
I am using GlassFish 4.1 with EclipseLink 2.5.2
