jstl数据库连接的问题
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<sql:setDataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost:1433;Database=?"
user="sa" password="?"
var="dataSource"/>
<sql:query var="result" sql="select * from jn_maoshuan"></sql:query>
为何这一行会出错？
<sql:setDataSource driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" --------------------编程问答-------------------- 贴一下错误信息吧，不然都不知道是什么错误啊

--------------------编程问答--------------------
javax.servlet.ServletException: javax.servlet.jsp.JspTagException: In <driver>, invalid driver class name: "java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver"看看异常就是没有追加jar包，看看环境jar追加了没有 --------------------编程问答-------------------- 根据错误信息提示应该是没加连接数据库的驱动包吧 --------------------编程问答-------------------- 为什么大家喜欢在页面端搞连接数据库这种东西
我觉得页面端主要还是负责传递数据、接收数据并显示
--------------------编程问答-------------------- 驱动jar包没有加貌似，
补充：Java , Web 开发
