异常在EJB 3使用appclient罐子：javax.ejb.EJBException异常：java.rmi.MarshalException：

我努力学习EJB 3，并在下文提到的情况，我现在无法弄清楚面临的一个问题。异常在EJB 3使用appclient罐子：javax.ejb.EJBException异常：java.rmi.MarshalException：

我有一个实体（书）来存储书的相关数据。
我已经创建了Stateless Bean和远程接口，并在glassfish 4中部署了该jar。
基本应用程序连接到主要方法，我需要使用appclient获取本书的详细信息。在这里，我收到一个错误“javax.ejb.EJBException：java.rmi.MarshalException：”

请查看下面的代码片段以获取更多详细信息。

它看起来像你的实体类没有序列化，实现Serializable接口在Book类

@Entity 
@NamedQuery(name = "findAllBooks", query = "select b from Book b") 
public class Book implements Serializable { 

@Id 
@GeneratedValue 
private long id; 

... 

}

希望这将有助于。
