无法加载类persistentBag

问题描述

我在下面有一个类，我从数据库加载这个对象，但是当我用JNDI地址调用这个方法时，给出一些有关 java.util.List 的kullainiciGrups属性的错误，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面;

您对这个persistenceBag异常有什么看法？
谢谢。

解决方案

您正在发送一个hibernate实体/集合。有几个问题：

• 集合可能未加载


• 端点可能没有因此在发送它之前，你应该初始化集合并取消它的代理（即获得原始集合）。这可能仍然不起作用，因为hibernate会设置自己的集合来实现 java.util.List 。所以从那里你有两个选择：
  $ b $ ul
  
• create new ArrayList（originalCollection） - 这会将元素复制到端点的类路径中的 ArrayList


• 添加hibernate中。

I have a class below and I load this object from the DB but when I call this method through with JNDI address, give some error about kullainiciGrups attribute which is a java.util.List, if this attribute removed, it works without exception. Stack trace is below the code block;

What do you think about this persistenceBag exception?Thanks.

You are sending a hibernate entity / collection. There are a few issues:

• the collection might not be loaded
• the endpoint might not have hibernate on its classpath.

So before sending it, you should initialize the collection and unproxy it (i.e. obtain the original collection). That may still not work, because hibernate sets its own collections that implement java.util.List. So from there you have two options:

• create new ArrayList(originalCollection) - this will copy the elements in a ArrayList
• add hibernate on the classpath of the endpoint.
