How to provide your own customized WAYF page

It is annoying to have a such long list in InCommon, but your users are limited to just several schools. Here is my solution:

1. Install apache-tomcat server on port 7080, the same machine runs SP but in
different port.

2. change wayfURL in SessionInitiator

http://yourdomain:7080/index.jsp

The following is a sample index.jsp I am using:

<html><%
   String timeInMillis = ""+System.currentTimeMillis();
%>

<body><center> <h1>University of California Grid Virtual Desktop
</h1>    
<div 
class="selector">        
<div class="list">            <h2>Which campus are you from: 
</h2>            





<form method="get" action="https://wayf.incommonfederation.org/InCommon/WAYF">                <p>                    <input type="hidden" name="shire" value="https://youdomain/Shibboleth.sso/SAML/POST" />                    <input type="hidden" name="target" value="cookie" />                    <input type="hidden" name="providerId" value="https://yourdomain/incommon" />                    <input type="hidden" name="time" value="<%=timeInMillis%>" />
