JBoss.org Community Documentation The extended portlet tag

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"/>

Example 3.8. Example use of the extended portlet tag

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.
