mysql - 是什么导致Hibernate SQL查询异常？

大家好，并且提前抱歉这篇文章，但我花了太多时间绕圈子，所以我希望有人能在这里为我揭开它。我在Tomcat上更新了一个webapp，我收到了以前版本中不存在的以下错误。虽然我非常有信心我修改的代码部分不应该受到责备，因为我在两个不同的开发服务器上测试了应用程序。

The production server is configured thus: CentOS 5.4 virtual server with tomcat 5.5.23 running mysql 5.0.77.
The two dev servers are: Windows XP SP2 running tomcat 5.5.23 with mysql 5.1.49
                         Mac OSX 10.6.6 Running tomcat 6 with mysql 5.1.51

该应用程序是使用struts（我可以收集的1.1）开发的，其中hibernate 3作为持久层。它只能在生产服务器上失败，因为我无法理解。我想提请你注意底部附近的 java.sql.SQLException 。经过一番长时间的搜索，我找到了this但是因为它是在几年前发布的（大约在开发这个应用程序之前的一年，我确信Hibernate已经从那个版本发展而来。因为我找不到实现他的方法解决方案。我使用Eclipse Helios作为IDE。感谢您抽出时间阅读本文，并向所有设法回复的人致谢。
