大家好，提前为这篇文章感到抱歉，但我花了太多时间绕着圈子转，所以我希望有人能在这里为我阐明一下。我在 Tomcat 上更新了一个 webapp，但出现了以下错误，该错误在以前的版本中不存在。虽然我很有信心我修改的部分代码不应该受到指责，因为我已经在两个不同的开发服务器上测试了该应用程序。
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（据我所知为 1.1）开发的，并使用 hibernate 3 作为持久层。由于某种我无法理解的原因，它只会在生产服务器上失败。我想提请您注意底部附近的java.sql.SQLException 。经过长时间的搜索，我发现了这个，但因为它是几年前发布的（在这个应用程序开始开发前大约 1 年，我确信 Hibernate 已经从那个版本演变而来。因为我找不到实现他的解决方案的方法。我使用Eclipse Helios 作为 IDE。提前感谢您抽出宝贵时间阅读本文，感谢所有设法回复的人。
