JSP Portlet Problem

Hi,

i'm new to the list and to Jetspeed. I read many documents about adding 
an own portlet to Jetspeed. I tried adding a JSP Portlet, but let's 
first talk about my setup.

I use Jetspeed 1.4b4 on a Mac, with java 1.4.1 and tomcat 5.x
I downloaded the binary form of jetspeed (WAR) and put in the the 
tomcat webapps folder. Then i startet tomcat. To make a long story 
short, jetspeed is alive and kicking at localhost:8080/jetspeed. So far 
so good.

The i wanted to add a JSP Portlet (which does nothing than a Hello 
World), and put a file "HelloWorld.xreg" in .../jetspeed/WEB-INF/conf:

<?xml version="1.0" encoding="UTF-8"?>

<registry>
     <portlet-entry name="HelloWorld" hidden="false" type="ref" 
parent="JSP" application="false">
         <meta-info>
             <title>HelloWorld</title>
             <description>Mein erstes Jetspeed JSP-Portlet</description>
         </meta-info>
         <parameter name="template" value="HelloWorld.jsp" 
hidden="true"/>
         <media-type ref="html"/>
         <category>demo</category>
         <category>jsp.demo</category>
     </portlet-entry>
</registry>


Additionally i put the file "HelloWolrd.jsp" in the folder 
.../jetspeed/WEB-INF/templates/jsp/portlets/html:

<%@ page language="java"
          session="false"
%>
<%@ taglib uri='/WEB-INF/templates/jsp/tld/template.tld' 
prefix='jetspeed' %>
<p>
Hello World!
</p>


Finally i logged into Jetspeed (using my own login) and added the 
HelloWorld JSP-Portlet as described in the Jetspeed-Tutorial (Add 
Portlet, then Save and Apply). The Frame of my Portlet is shown, but i 
get no Hello World, but an error message saying:

JSPViewProcessor: Could not include the following JSP Page: 
[HelloWorld.jsp] : null


I have no idea where look for my error. If anyone can help me out i 
would be very grateful.



Many thanks in advance,

Bela

"HelloWolrd.jsp" -> That's a type, not the source of the error. Sorry.

The spelling of HelloWorld.jsp is correct in my portal. As i said 
earlier the mispelling you mentioned was only a typo in my mail. But 
thanks anyways.

Still i didn't get rid of the error and i still have no idea why... :-(

Try  to  add this portlet conf in demo-portlets.xreg  or  create
local-portlets.xreg and give a shot.
