1.安装:SQL Server 2000 Driver for JDBC Service Pack 3
下载安装JDBC SP3
里面的安装包
按照提示安装可以了.成功后有三个文件要使用:
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msbase.jar
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/msutil.jar
c:/program files/Microsoft SQL Server 2000 Driver for JDBC/lib/mssqlserver.jar
2.测试代码
新建类文件Connect.java.

成功后控制台输出:

3.问题:
在测试中控制台老输出下面的错误!
找资料找了很久.都说把jdbc安装后的三个jar文件的路径放进环境变量里可以了但我试了不行的!
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
.........
Error Trace in getConnection() : com.microsoft.jdbc.sqlserver.SQLServerDriver
Error: No active Connection
请教了别人才找到办法:
包资源管理器-->包名右键"构建路径"-->配置构建路径-->java构建路径-->库-->添加外部JAR
把那三个JAR选择进去就可以了.
添加后三个JDBC文件就有了.
