This article illustrates jsp's simple implementation of sharing information between pages. Share with you for your reference. The details are as follows:

Here we demonstrate the jsp parent page to get configuration information on the child page, reducing code duplication.

1. Parent page:


<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html ng-app>
 <head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <script src="<%=cdn%>/angular.js/1.3.0-beta.13/angular.min.js"></script>
  <script src="<%=cdn%>/jquery/2.1.1/jquery.min.js"></script>
  <title>JSP  Parameters are shared between pages </title>
 </head>
 <body>
  <h3>cdn url : <%= cdn %></h3>
   <label>Name:</label>
   <input type="text" ng-model="yourName" placeholder="Enter a name here">
   <%@include file="child.jsp" %>
 </body>
</html>

2. Subpage:


<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%!
static final String cdn = "http://cdn.staticfile.org"; 
%>
<div>
  <h1>Hello {{yourName || 'world' }}!</h1>
</div>

Hope this article described to everyone JSP program design is helpful.
