org.apache.openjpa.persistence.PersistenceException:空 [英] org.apache.openjpa.persistence.PersistenceException: null

问题描述

第二行导致下面列出的异常.该代码实际上可以在测试服务器上运行，但是在我的盒子上却炸裂了.谁能提供线索我需要解决的问题?

The second line is causing the exception listed below. This code actually works on the test server, but is blowing up on my box. Can anyone offer a clue what I need to look at to solve this?

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

推荐答案

我将记录所有针对此问题的解决方案.

I'll document all my solutions to this problem.

• 这是第一分辨率.线索是此处.我升级了Open JPA从2.2.0到2.2.2&异常消失了，所以看起来 这是一个错误.

• This is the 1st resolution. The clue was here. I upgraded Open JPA from 2.2.0 to 2.2.2 & the exception went away, so it appears that it was a bug.

这又发生了.我缺少cglib.2.2.3.zip和/或 cglib-nodep-2.2.3.jar.

This happened again. I was missing cglib.2.2.3.zip and/or cglib-nodep-2.2.3.jar.
