跟着程序走了以下，确实没有这个方法，郁闷了一天

经过反复调试后发现有几种可能造成这个原因

1.驱动程序的版本不对

2 .sql server 2000没有打补丁 必须打补丁

3 .检查sql server 2000 的驱动程序mssql.jar，msbase.jar，mssqlserver.jar，msutil.jar存放位置对不对，一般放在tomact/commen/lib下就可以,或放进class_path，或webinfo/lib下，一般情况下，放一个地方就可以了

4 .位置方对了还不行 那可以考虑jdbc驱动程序的版本对不对，如果你打了 sp2补丁 那么也要用for sp2 driver

到此，相信大家对“java链接sql server 2000后出错的原因”有了更深的了解，不妨来实际操作一番吧！这里是创新互联网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
