我的SQL数据库为什么连接不上呢？

import java.sql.*;

public class JDBCExample{
public static void main(String args[]){
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
      Connection conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=master","sa","");
      Statement stmt = conn.createStatement();
      ResultSet rs = stmt.executeQuery("select * from student");
      while(rs.next()){
System.out.print("学号: " + rs.getInt(1));
System.out.print("\t姓名: " + rs.getString(2));
System.out.print("\t性别: " + rs.getInt(3));
System.out.println("\t年龄: " + rs.getString(4));
}
rs.close();
stmt.close();
conn.close();
}catch(Exception e){
      e.printStackTrace();
}
}
}

下面的是异常信息：

SQL驱动程序没有打到JAVA包下面
*:\*\Java\jdk1.6.0_03\jre\lib\ext
将SQL下的JAVA包复制到这个位置就行了！

补充一点 sql server数据库还需要安装sp4补丁

好像是SP3补丁吧！

[em10] SQL2000-KB884525-SP4-x86-CHS.EXE这是下载的文件名你说SP4还是SP3
