SQL2000 关于 Java JDBC 驱动的安装和设定

解决方法摘自 studyhardlr 『http://www.Javathinker.org/bbs/topic.jsp?db=7&topic=3749』
1、首先要记得SQL2000 要打上sp3以上的补丁.(建议用sp4)
2、装上SQL Server 2000 Driver for JDBC Service Pack 3

3、安装完SQL Server 2000 Driver for JDBC Service Pack 3，它默认安装在C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC 里，在C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib 这个目录里有三个jar文件:
msbase.jar,msSQLserver.jar,msutil.jar，一定要记得把这三个文件copy到你所安装的jdk下的jre目里，这里我以的我的安装配置进行解说:
我的jdk是jdk1.5.0_09，默认安装在:
C:/Program Files/Java 里，在这个C:/Program Files/Java目录下有两个文件夹:
jdk1.5.0_09 目录 和 jre1.5.0_09目录，
前面说的的那三个jar文件一定要copy到jdk1.5.0_09目录里下的jre目录下的lib目录下的ext目录下，我这里的完整路径为:
C:/Program Files/Java/jdk1.5.0_09/jre/lib/ext
4、设置classpath，把这个三个jar文件，加进去
5、SQL2000要设置为混合登录模式(windows 和 SQL)
