使用<jsp:forward>和<jsp:param>

a.jsp

 

<%@ page language="java" contentType="text/html; UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>java_bean</title>
</head>
<body>
<!-- 判断一个邮箱是否为标准邮箱+comb.Email+/test/a.jsp+/test/result.jsp -->
    <form action="/Weblearn/test/result.jsp" method="post">
        <table align="center" width="300px" border="1" height="150px">
            <tr>
                <td colspan="2" align="center">
                    <b>邮箱认证系统</b>
                </td>
            </tr>

            </tr>
            <tr>
