resteasy inject java ee bean

Question

In Rest easy REST endpoint i'm trying to create new user from JSON object. To save new entity i'm using entityManager( datasource is ready and exists), but entityManager doesn't injected from Persistance context. EJB beans doesn't inject too. This looks like that wildfly not provide any injection in RestEasy end point. Need any help to fix injection where.

an answer was editing RestService:

@ApplicationPath("/rest")
public class RestService extends Application
{
    private Set<Class<?>> classes = new HashSet<>();
    private Set<Object> singletons = new HashSet<Object>();

    public RestService() {
        singletons.add(new BudgetRestService());
        classes.add( UserService.class);
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }

    @Override
    public Set<Class<?>> getClasses() {
        return classes;
    }
}
