EntityManager sempre NULL no EAR

Olá pessoal, estou tentando criar um projeto EAR teste com EJB + Glassfish porém meu EntityManager vem sempre null e não sei mais o que pode ser… abaixo segue a estrutura e os códigos(bem simples) apenas para teste

Main.java

public class Main {
    public static void main(String[] args) {      
        NewClass newclass = new NewClass();
        List<Person> listP = new LinkedList<Person>();
        for (Person person : newclass.listPeople()) {
            System.out.println("People " + person.getName());
        }
    }
}

NewClass.java

@Named
public class NewClass {
    
    @Inject
    public PersonSessionBeanLocal personSessionBeanLocal;
    
    public List<Person> listPeople(){
        personSessionBeanLocal = new PersonSessionBean();
         return personSessionBeanLocal.getPeople();
    }
    
}

PersonSessionBean.java

@Stateless
public class PersonSessionBean implements PersonSessionBeanLocal {

    @PersistenceContext
    public EntityManager em;

    public EntityManager getEm() {
        return em;
    }

    @Override
    public List<Person> getPeople() {
        List<Person> list =  new LinkedList<Person>();
        list = getList(Person.class, "Select p From Person p");
        return list;
    }

   public <T> List<T> getList(Class<T> classToCast, String query, Object... values){
        Query qr = createQuery(query, values);       
        return qr.getResultList();
    }
   
    private Query createQuery(String query, Object[] values) {
        Query qr = em.createQuery(query);
        if(values != null){
            for (int i = 0; i < values.length; i++) {
                Object object = values[i];
                qr.setParameter(i+1, object);
            }
        }
        return qr;
    }
}

PersonSessionBeanLocal.java

@Local
public interface PersonSessionBeanLocal {
 
    public List<Person> getPeople();
    
}

Person.java

@Entity
@Table(name = "person")
@XmlRootElement
public class Person implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @NotNull
    @Column(name = "id")
    private Long id;
    @Size(max = 255)
    @Column(name = "name")
    private String name;

    public Person() {
    }

    public Person(Long id) {
        this.id = id;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Person)) {
            return false;
        }
        Person other = (Person) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "entities.Person[ id=" + id + " ]";
    }
    
}

Obrigado!
