我的程序开始是可以运行的，但是进来不知道怎么搞的就出问题了
源程序是这样的
<%@ page contentType="text/html; charset=gb2312" language="java" import="com.*,java.util.*,java.io.*" %>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<jsp:useBean id="user" class="com.User" scope="page">
<jsp:setProperty name="user" property="*"/>
</jsp:useBean>
<jsp:useBean id="loginBean" class="com.LoginBean" scope="page"/>

<body>
<%
String name=request.getParameter("name");
String password=request.getParameter("password");
String type=request.getParameter("kind");
String log=loginBean.getLoginInfo(name,password,type);
if(log.equals("user")){
session.setAttribute("name",user.getName());
session.setAttribute("password",user.getPassword());

response.sendRedirect("userpage.jsp");}
if(log.equals("manager")){
session.setAttribute("name",user.getName());
session.setAttribute("password",user.getPassword());

response.sendRedirect("manager.htm");}
else{
%>
 

非法用户!
请您重新填写…
 
<a href="login.htm" >返回登录界面</a>
 
<% }
%>
<%=log%>
<%=request.getParameter("kind") %>
<%=user.getType() %>

<center>
</center>
</body>
</html>

进入管理员界面可以，
但是进入用户界面就报错，好像是没有连上数据库，前一段时间这个页面是可以成功运行的。源程序我没有改动，近来老报这样的错
