我们有一个应用程序，它在服务器（jboss.4.2.1.GA）端有一个swing客户端和java应用程序。我们正在使用ejb3。 在我们的应用程序中，我们在某些时候成功创建了一张发票并将其显示给用户，但是当用户想要查询发票时，我们会收到以下错误。重新加载发票后，用户可以更改发票而不会出现任何错误。 发票创建代码，发票更改和完整错误堆栈如下：

答案 0 :(得分：2)
您不应该将Hibernate创建的类直接序列化到您的客户端，因为您正在获取发送的Hibernate工件。这是导致NoClassDefFound错误的原因。
您应该使用自己创建的值对象并将Hibernate结果转换为这些对象。这将使您无法访问Hibernate特定类的隐藏链接。
答案 1 :(得分：2)
您使用fetch = FetchType.LAZY定义了一个或多个实体关系。 作为此关系一部分的关联实体将替换为AbstractComponentType。
由于类org.hibernate.type.AbstractComponentType未包含在JBoss客户端jar中，因此JVM抛出了ClassNotFoundException。
因此，要解决此问题，您可以将FetchType更改为EAGER，或者在向客户端发送响应之前，可以确保在会话bean中初始化关系。
（你也可以在你的类路径中添加一个包含AbstractComponentType类的jar，只要客户端不会尝试访问被这个AbstractComponentType替换的实体 - 我不会推荐这最后一个替代。）< / p>
答案 2 :(得分：1)
底层问题是ServerResponse正在填充引用org / hibernate / type / AbstractComponentType的数据，而hibernate类不在swing客户端的类路径上。您可以将hibernate类添加到客户端类路径中，但更有可能的是发回一个比您想象的更重且包含更多引用的对象。
关于该类的信息不足以及您的发票一般如何制作以了解更多信息，但异常表明这是核心问题。
答案 3 :(得分：0)
当您尝试在保存时将Invoice实例发送到服务器时，堆栈跟踪指示客户端中没有类“org.hibernate.type.AbstractComponentType”。
在某个地方定义了一个错误，或者你必须将hibernate JAR添加到客户端的类路径中。
