EJB 项目错误:javax.naming.NameNotFoundException

Question

我在 NetBeans 8.2 中使用 wildfly 10.1 制作了 EJB 项目。

我为此创建了两个项目：EJBComponent （LibrarySessionBean.java，LibrarySessionBeanRemote.java）和EjbTester（EJBTester.java）。

尝试运行 EJBTester 时出错.java：

我的代码：

图书馆会话豆.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();
}

在不同的项目中制作的客户端应用程序。

更改代码以匹配此处解释的内容：https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

检查 "jboss-ejb-client.jar" 在客户端类路径中是否可用？
