在jsp中调用javaBean时,是不是一定得配置web.xml文件?里面的内容要根据什么来写啊?我注册的内容提交不了,提交目的文件代码如下:
<%@ page contentType="text/html; charset=gb2312"%>
<%@ page language="java" import="java.sql.*"%>
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<html>
<head>
<title>注册确认 </title>
</head>
<body>
<jsp:useBean id="bidBean" scope="page" class="firm.firm"/>
<%
String name1=new String(request.getParameter("user_id").getBytes("8859-1"));
String password=request.getParameter("password");
String email=request.getParameter("email");
String qq=request.getParameter("QQ");
String domID=request.getParameter("domID");
String sql="select * from user where name='"+name1+"'";
ResultSet rs=bidBean.executeQuery(sql);
if(rs.next())
{
rs.close();
session.putValue("register_message","该会员已经存在，请重新输入！");
%>
<jsp:forward page="register.jsp"/>
<%
}
else
{
rs.close();
}
%>
<form method=post action="ok_register.jsp">
<input type="hidden" name="user_id" value="<%=name1%>">
<input type="hidden" name="password" value="<%=password%>">
<input type="hidden" name="email" value="<%=email%>">
<input type="hidden" name="qq" value="<%=qq%>">
<input type="hidden" name="domID" value="<%=domID%>>
<font color="red"><%=name1%>您好，请检查您的注册信息是否正确！</font><br><br>
<table border="1" cellspacing="0" width="332" bgcolor="#f0f8ff" bordercolorlight="#4da6ff"
bordercolordark="#ecf5ff">
<tr>
<td>登录名：</td>
<td><%=name1%></td>
</tr>
<tr>
<td>密码：</td>
<td><%=password%></td>
</tr>
<tr>
<td>E-mail:</td>
<td><%=email%></td>
</tr>
<tr>
<td>QQ:</td>
<td><%=qq%></td>
</tr>
<tr>
<td>宿舍号：</td>
<td><%=domID%></td>
</tr>
</table>
<br>
<input name="submit" type="submit" class="buttonface" value="提交">
<input type="button" name="button" class="buttonface" onclick="history.back()" value="修改">
</form>
</body>
</html>
在注册页面点击提交按钮后就会出现如下东西:
