在线急等，JSP网页表单提交后为什么得不到表单中的数据
JSP网页表单提交后为什么得不到表单中的数据，提交后下页的几个赋值语句
if(request.getParameter("text")!=null)
question.questionText =request.getParameter("text");
if(request.getParameter("xuanX1")!=null)
question.questionText =question.questionText+"A"+request.getParameter("xuanX1");
if(request.getParameter("xuanX2")!=null)
question.questionText =question.questionText+"B"+request.getParameter("xuanX2");
if(request.getParameter("xuanX3")!=null)
question.questionText =question.questionText+"C"+request.getParameter("xuanX3");
if(request.getParameter("xuanX4")!=null)
question.questionText =question.questionText+"D"+request.getParameter("xuanX4");
if(request.getParameter("questionType")!=null)
question.questionTypeNo =new String(request.getParameter("questionType").getBytes("ISO-8859-1"),"gb2312");
if(request.getParameter("answer")!=null)
question.questionAnswer =new String(request.getParameter("answer").getBytes("ISO-8859-1"),"gb2312");
通过tomcat看这几个变量最后都是空值，这是为什么啊，我觉得是表单写的不对
<%@ page contentType="text/html; charset=gb2312" language="java"%>
<%@ page import="java.sql.*,com.object.*,com.database.*" %>
<jsp:useBean scope="page" id="question" class="com.object.Question" />

[解决办法]
看看infocheck里面是什么内容，其它表单控件如subject有值提交上去吗
那些为空的表单控件，真的有填写内容吗
[解决办法]
保存在session里调用
jsp提交第一个表单的参数保存在session里，然后你提交第二个表单的时候就可以获取第一个session里的参数，先设置，再取值
session.setAttribute("text",text);
session.getAttribute("text");
