Injecting one ejb bean inside another within the same jar module not working

Question

I have two beans in my jar module -> bean A:

@Singleton
public final class A {
    public String getS() {
        return"";
}

and a second bean B within the same jar module:

@Stateless
public final class B {
    @Inject
    private A a;

    public String getAS() {
        a.getS() // -> NullPointerException
    }
}

I have the file beans.xml in

src/main/resources/META-INF/

<groupId>javaee</groupId>
<artifactId>javaee-api</artifactId>
<scope>provided</scope>

is added to pom.xml, but still injected A is null.

In a generated jar file beans.xml is present

whether I missed something?

@Laertes Indeed I don't really see beans.xml in my jar file, hymm what that might be cause? — michalavis, Jan 31 '20 at 08:43
@Kukeltje javaee api is provided and class B is stateless ejb bean — michalavis, Jan 31 '20 at 08:44
@Kukeltje I wrote about javaee dependency and what difference does it make whether B is stateless or POJO should be injectable — michalavis, Jan 31 '20 at 10:29
And how do you know injection is not working? I don't see any code where the injected bean is used that e.g. throws an NPE due to the injection not working. And does 'injection' work if you change `@Inject` to `@EJB`? — Kukeltje, Jan 31 '20 at 11:26
Yes it's throw NullPointerException and I can also see it in debug mode. change on @EJB throw CreationException -> NameNotFoundException — michalavis, Jan 31 '20 at 12:16

The default place for the beans.xml for building jars with maven would be in

src/main/resources/META-INF/

That's where I have the beans.xml – michalavis Jan 31 '20 at 12:41
If the path is src\main\resources\META-INF\beans.xml Maven puts it automatically in the rigth place in the jar. You might double check it... – Laertes Jan 31 '20 at 17:06
