RestEasy @EJB returning zero

I have a jax-rs service implemented using RestEasy, I use Jboss as7 and have implemented signleton ejb with @Signleton annotation. The icon starts when the server starts (@startup), and I would like to enter it in jax-rs using @EJB. The problem is that the class is always null, and I'm starting to be mistaken, because in every tutorial I saw, this is how they introduce ejb. Should I use any special XML file? what am I doing wrong?

@Path("/")
public class Service extends Application{
@EJB
private GlobalStore store;
public Service(){
fromejbstore = store.getSentiment();//null pointer is thrown
}
}

The ejb signal is:

@Singleton
@Startup
public class GlobalStore {
 Sentiment sentiment;
 @PostConstruct
public void initialize() {
 //do something
}
public Sentiment getSentiment(){return sentiment;}
}
