不好意思，刚才忘记贴程序了

<%/*Class.forName("com.internetcds.jdbc.tds.Driver").newInstance();

Connection con= DriverManager.getConnection(url,"qcc","qcc");
Statement smt=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs;

String sql="select * from infomation";
System.out.println(sql);
rs=smt.executeQuery(sql);
while (rs.next()){

System.out.println(rs.getString(1));

}

//这是直接连接

import java.sql.*;
public class conn{
private String userName="";
private String password="";
public conn(String userName,String password){
this.userName = userName;
this.password = password;
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();

Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=yourdb
Connection conn= DriverManager.getConnection(url,user,password);

String sql="select * from test";
do{
ResultSet rs=stmt.executeQuery(sql);
}while(rs.next())
}
}
以上就是一个简单的连接类了!!

二、jsp连接Sql Server7.0/2000数据库
testsqlserver.jsp如下：
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs";
//pubs为你的数据库的
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from test";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为：<%=rs.getString(1)%>
您的第二个字段内容为：<%=rs.getString(2)%>
<%}%>
<%out.print("数据库操作成功，恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>

这是一个简单的连接sqlserver数据库的例子，你要写成java文件只需要把里面的连接以及
其他执行的executeQuery以及executeUpdate等的操作封装在你设计的类中就可以那！
