WebWork2+Spring1+Hibernate3连接数据库出现问题

程序使用了较老的WSH（WebWork2+Spring1+Hibernate3）的搭配框架，数据库使用了MySQL5，容器是Tomcat，在一台电脑上可正确运行，而转移到另一台上却不行了，报错如下，不知道为什么连接不上数据库？
恳请哪位高人指教下面错误解决方法：
org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection
org.hibernate.exception.GenericJDBCException: Cannot open connection
