无法加载类persistentBag

我有一个类下面，我从数据库中加载这个对象，但是当我通过JNDI地址调用这个方法时，给出一些有关kullainiciGrups属性的错误，这是java.util.List，if这个属性被删除，它毫无例外地工作。堆栈跟踪位于代码块的下方;无法加载类persistentBag

您对这个persistenceBag异常有什么看法？谢谢。

您正在发送一个hibernate实体/集合。有几个问题：

收集可能不会被加载
端点可能没有在其类路径休眠。

因此，在发送它之前，您应该初始化集合并取消其代理（即获取原始集合）。这可能仍然不起作用，因为hibernate设置了自己的集合，实现了java.util.List。所以，从那里，你有两个选择：

创建new ArrayList(originalCollection) - 这将在ArrayList
添加元素复制冬眠在端点上的类路径。

如果没有List属性，Hibernate会在类路径上使用。我想要返回Kullanici Class，所以如何创建一个新的ArrayList，我尝试在get方法上创建，但又失败了。 – 2010-12-10 09:22:39

使用DTO-Pattern将所有需要的信息复制到另一个类中。或者将您的映射更改为急切加载，**可能会有所帮助。 – 2010-12-10 09:57:36

@ckuetbach我已经将对象转换为DTO，但在转换之前抛出了此异常。 – 2010-12-10 10:38:52
