Problem setting JSP Portlet Template

[Jonathan Hawkins <jo...@Cedar.com>]

I have defined two JSP Pages , portlet1.jsp and portlet2.jsp. I have
registered a portlet in portlets.xreg and defined the template as
portlet1.jsp. On portlet1 there is link to portlet2.jsp. I have created an
action class that pickes up the parameter and attempts to redefine the
template as portlet2.jsp. What happens is that the portlet never displays
portlet2.jsp. I include the relevant code below and any assistance would be
greatly appreciated.

PORTLET1.JSP

<%@ taglib uri='/WEB-INF/templates/jsp/tld/template.tld' prefix='jetspeed'
%>

<%@ page import="
	javax.naming.*,
	javax.ejb.*,
	java.rmi.RemoteException,
	java.rmi.Remote,
	java.util.*,
	java.text.*,

	org.apache.turbine.util.template.TemplateLink,
	org.apache.turbine.services.jsp.JspService,
	org.apache.turbine.services.resources.TurbineResources,
	org.apache.jetspeed.util.servlet.EcsServletElement,
	org.apache.ecs.ConcreteElement,
	org.apache.ecs.StringElement, 
" session="true" %>

<% RunData rundata = (RunData)request.getAttribute("rundata"); %>

<div align="left">
<form method="POST" 
      action="<jetspeed:dynamicUri/>" 
      enctype="application/x-www-form-urlencoded">

<input name="action" type="hidden" value="<%= TurbineResources.getString(
"action.PerformTask" ) %>">

<% out.println("Parameter passed is " + request.getParameter("task")); %>

<p>
<b>Portlet 1</b>This is Portlet 1
<a href="portal/action/PerformTask?task=PORTLET2">Show Portlet2</a>
</p>
</form>

PORTLET2.JSP
