Question

第二行导致下面列出的例外。这段代码实际上可以在测试服务器上运行，但是在我的盒子上爆炸了。任何人都可以提供解决这个问题的线索吗？

   TypedQuery<ed> _TypedQuery = _EntityManager.createQuery(_CriteriaQuery);
   List<ed>       _edList     = _TypedQuery.getResultList();

异常

Answer 1

我会记录我对这个问题的所有解决方案。

这是第一个决议。线索是here。我升级了Open JPA从2.2.0到2.2.2＆amp;例外消失了，所以看来这是一个错误。
这又发生了一次。我缺少cglib.2.2.3.zip和/或 CGLIB的节点p-2.2.3.jar。

org.apache.openjpa.persistence.PersistenceException：null
