要求：使用jsp+servlet完成一个表单验证，通过表单提交信息给Servlet，Servlet获取到信息后，处理，把信息放到request对象中，如果用户提交的姓名为空，不能跳转，否则，将信息全部显示出来。
//index2.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
