我使用wildfly 10.1在NetBeans 8.2中创建了EJB项目。
我为此创建了两个项目：EJBComponent（LibrarySessionBean.java，LibrarySessionBeanRemote.java）和EjbTester（EJBTester.java）
我试图运行EJBTester.java时出错：

我的代码：
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)

List<String> bookShelf;
public LibrarySessionBean(){

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

更改代码以符合此处说明的内容：https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI
检查＆＃34; jboss-ejb-client.jar＆＃34;在您的客户端类路径中可用吗？
