为了完成老师给的简单的jsp模拟登录，利用jsp:forward实现
index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>$Title$</title>
</head>
<body>
<h1>模拟登陆</h1>
<form action="forward.jsp">
<input type="text",name = "id" id = "id">账号<br>
<input type="password",name = "pwq" id = "pwq">密码<br>
<input type="submit" value="登录">
</form>
</body>
</html>
在forward中尝试判断 ，密码是否正确，可是却一直获取不到，打印输出是null？？？为什么 哪里写错了
forward.jsp
