The extended portlet consists of a JSP tag file located in the folder
/WEB-INF/tags/portal
of Simple Portal's WAR file.
<%@ page contentType="text/html" %> <%@ page language="java" %> <%@ taglib prefix="xportal" tagdir="/WEB-INF/tags/portal" %> ... <xportal:portlet name="GoogleMap" applicationName="samples-google-portlet"/> ...

You can consider this extension pretty much like a JSP include, just more powerful. More specifically, the JSP tag file can be edited and tweaked to your needs.
