本人用的是环境是Spring+Hibernate+Struts，后台是SQL Server 2000.
原来后台用的是Mysql，调试正常，后来想移植到SQL Server 2000中，仅把数据库连接相关配置文件修改了，但出错，提示：
其他异常：Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection 配置文件主要内容如下： <!-- 定义数据源Bean，使用C3P0数据源实现 -->
