感谢各位的帮助！
我没有使用jdbc-odbc桥的方法连接数据库了！我现在使用的是直接连接数据库！
我下载了一个sql server 2000 driver for jdbc，按照上面的步骤安装，结果出现了以下的错误提示：

从错误提示看是因为：classpath的设置没有对！
可是我进入我电脑的环境变量设置里面没有classpath这一项，我自己添加了一个，按照说明输入了变量:安装路径+lib\msbase.jar lib\msutil.jar lib\mssqlserver.jar
但是仍然不行！后来我进入注册表找到了jvm的classpath,不知该如何添加，于是直接把路径添加在后面！可是还是不行！
那位前辈帮帮我！！！！
