Ошибка проекта EJB: javax.naming.NameNotFoundException

Question

Я сделал проект EJB в NetBeans 8.2 с wildfly 10.1.

Я создал два проекта для этого: EJBComponent (LibrarySessionBean.java, LibrarySessionBeanRemote.java) и EjbTester (EJBTester.java)

ошибки, когда я пытаюсь запустить EJBTester.java:

Мой код:

LibrarySessionBean.java

package com.ejb.stateless; 

import java.util.ArrayList; 
import java.util.List; 
import javax.ejb.Remote; 
import javax.ejb.Stateless; 

@Stateless 
@Remote(LibrarySessionBeanRemote.class) 
public class LibrarySessionBean implements LibrarySessionBeanRemote { 

    List<String> bookShelf;  

    public LibrarySessionBean(){ 
     bookShelf = new ArrayList<>(); 
    } 

    @Override 
    public void addBook(String bookName) { 
     bookShelf.add(bookName); 
    }  

    @Override 
    public List<String> getBooks() { 
     return bookShelf; 
    } 
} 

LibrarySessionBeanRemote.java

package com.ejb.stateless; 

import java.util.List; 
import javax.ejb.Remote; 

@Remote 
public interface LibrarySessionBeanRemote { 

    void addBook(String bookName); 

    List getBooks(); 

}

Изменить код, чтобы соответствовать, что объясняется здесь: https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

Проверьте, правильно ли "JBoss-EJB-client.jar" доступна в клиентском пути к классам?
