1、首先要記得sql2000 要打上sp3以上的補丁.(建議用sp4)
2、裝上SQL Server 2000 Driver for JDBC Service Pack 3

3、安裝完SQL Server 2000 Driver for JDBC Service Pack 3，它默認安裝在C:/PRogram Files/Microsoft SQL Server 2000 Driver for JDBC 里，在C:/Program Files/Microsoft SQL Server 2000 Driver for JDBC/lib 這個目錄里有三個jar文件:
msbase.jar,mssqlserver.jar,msutil.jar，一定要記得把這三個文件copy到你所安裝的jdk下的jre目里，這里我以的我的安裝配置進行解說:
我的jdk是jdk1.5.0_09，默認安裝在:
C:/Program Files/Java 里，在這個C:/Program Files/Java目錄下有兩個文件夾:
jdk1.5.0_09 目錄和 jre1.5.0_09目錄，
前面說的的那三個jar文件一定要copy到jdk1.5.0_09目錄里下的jre目錄下的lib目錄下的ext目錄下，我這里的完整路徑為:
C:/Program Files/Java/jdk1.5.0_09/jre/lib/ext

4、設置classpath，把這個三個jar文件，加進去

5、sql2000要設置為混合登錄模式(windows 和 sql)
