EJB injection impossible in a war application deployed on wildfly via cargo maven plugin

Question

I deploy a war application using cargo maven plugin (wildfly 10 app server) and this happens successfully! But i can't injecting an ejb in a class. This is the console when i exec cargo:run(see the null instance in tail of log..)

My ejb is Timer2EJB:

import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.enterprise.concurrent.ManagedScheduledExecutorService;


    @Stateless
    public class TimerEjb2 {


        @Resource//(lookup="java:jboss/ee/concurrency/scheduler/default")
        private ManagedScheduledExecutorService executorService; 


        public TimerEjb2() {

        }

        public void startTask(PushEndPoint pushEndpoint){
            executorService.scheduleAtFixedRate(pushEndpoint, 1, 50, TimeUnit.MILLISECONDS);
        }

        public void shutdownTask(){
            executorService.shutdown();
            try {
                executorService.awaitTermination(3000, TimeUnit.SECONDS);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

    }

pushEndpoint implements Runnable. But when i execute this class the injection not happens:

import javax.ejb.EJB;

public class Testejb {

    @EJB
       TimerEjb2 timerEjb2;

    public void test(){
        System.out.println(timerEjb2); <--this is null in log!
    }
}

the same things if i add (lookup="java:global/dwrexmio/TimerEjb2!com.cadit.bean.TimerEjb2") before @EJB

In webapp\WEB-INF there is web.xml and the beans.xml and ejb-jar.xml:

what's wrong?

Thank you very much!

Answer 1

You're Testejb is not managed by the container and therefore the EJB cannot be injected. You need to run your test with something like Arquillian that can run tests in the container.

Answer 2

Add @Stateless to your Testejb otherwise it is not managed by the application server and dependencies are not injected.
