数据库 sql server 2000 已经打上了sp4补丁
错误提示
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)
at com.microsoft.jdbc.base.BaseExceptions.getException(Unknown Source)

at com.microsoft.jdbc.base.BaseDriver.connect(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)

代码
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
System.out.println("驱动程序已加载");
conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=sheji_data","sa","admin");
System.out.println("OK,成功连接到数据库");

执行过程中可以看到"驱动程序已加载"然后就是
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.

在网上查的资料说打上补丁就行了,可是不知道为什么我这里还是出错
请个位高手帮帮忙
谢谢

还得安装jdbc驱动，完全版。

一，你确定你安装的jdbc是否完全版，因为有个单机版只能连接本机上的sql，单机版约2m，完全版约6.5m
二、安装好jdbc后，假如目录在C:\ProgramFiles\MicrosoftSQLServer2000JDBC,打开Jbuilder，选择Tools-->;ConfigureLibraries，然后在左边的列表框下选择New，填入：Name:sql，Location:UserHome，然后点击Add，加入目录C:\ProgramFiles\MicrosoftSQLServer2000JDBC\lib，确定
三、Project-->;PrjectProperties-->;Paths-->;RequiredLibraries-->;Add
加入刚才添加的UserHome/sql确定
四、Tools-->;EnterpriseSetup-->;DatabaseDrivers-->;Add，加入UserHome/sql，添加之后在列表框中显示的是sql.config，确定，重新启动JBuilder
五、Tools-->;DatabasePilot-->;View-->;Options-->;Drivers-->;Add
填入
Driverclass:com.microsoft.jdbc.sqlserver.SQLServerDriver
SimpleURL:microsoft:sqlserver://localhost:1433;DatabaseName=mybase
确定之后，Tools-->;DatabasePilot-->;New的Driver里选择
com.microsoft.jdbc.sqlserver.SQLServerDriver
在URL里填入：
microsoft:sqlserver://服务器Ip地址或主机名:1433;DatabaseName=数据库名，确定！
双击或点击+号输入sql数据库的用户名和密码，就完成了JB与sql的连接！
连接代码可以查看Source！

楼上的回答的很详细啊!我也正在看这一块.

连接Access数据库啊
import java.sql.*;

}
不用数据源.
