代码好像有点问题,好像没什么实际意义.

运行环境tomcat5.5.12，现有一页面和一javaBean
<%@page contentType="text/html;charset=gb2312" %>
<jsp:useBean id="user" class="com.yj.User" scope="page"> //问题出在这里，我输入用户名点登陆提交的还是这个页面
<jsp:setProperty name="user" property="*"/> //如果scope设为page,则能显示出loginname,而我设为
</jsp:useBean> //session，为什么获取不到值?session的范围大于page啊
<html>
<body>
<h1>用户登陆</h1>
<form action="login1.jsp" method="post">
<table>
<tr>
<td>用户名</td>
<td><input type="text" name="loginname" value="${user.loginname}"></td>
</tr>
<tr>
<td>密码</td>
<td><input type="password" name="password"></td>
</tr>
<tr>
<td>真实姓名</td>
<td><input type="text" name="username"></td>
</tr>
<tr>
<td>年龄</td>
<td><input type="text" name="age"></td>
</tr>
<tr>
<td>地址</td>
<td><input type="text" name="address"></td>
</tr>
<tr>
<td align="right"><input type="submit" value="登录"></td>
<td><input type="button" value="注册"></td>
