I tried it again with a simpler web application. I converted "blank.war"
(it is part of myfaces-examples downloaded from apache site) into a
portlet but still getting the same error while adding it to a page.
The stack trace in jetspeed.log file is as follow:

The MyFacesGenericPortlet.class is in /WEB_INF/lib/myfaces-impl.jar. I
put it in common/lib also.
Moreover, I added the following to web.xml:
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener<
/listener-class>
</listener>
<servlet>
<servlet-name>JetspeedContainer</servlet-name>
<display-name>Jetspeed Container</display-name>
<description>MVC Servlet for Jetspeed Portlet
Applications</description>
<servlet-class>org.apache.jetspeed.container.JetspeedContainerServlet</s
ervlet-class>
<init-param>
<param-name>contextName</param-name>
<param-value>blank</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JetspeedContainer</servlet-name>
<url-pattern>/container/*</url-pattern>
</servlet-mapping>
Still I am getting the same error.
I don't know whats wrong with it.
Has anyone come across this problem?
Please help.
Thanks,
Sunil

Subject: How to turn a JSF into a portlet
Hi All,
I tried converting a sample myfaces (I took simple.war that comes with
myfaces example) web application into a portlet application on
jetspeed2.
I came to know that myfaces application can be readily converted into a
portlet app by simply adding a portlet.xml and ensuring that there are
no redirects in faces-config.xml
I made the changes and deployed it on jetspeed2. The application was
deployed successfully and registered in search engine.
But when I add the portlet on a page, it displays an error message
saying "Cannot create Portlet instance
org.apache.myfaces.portlet.MyFacesGenericPortlet for Portlet Application
simple "
I searched on net but it wasn't of any help.
I checked the jar files and the above mentioned class is in the lib.
Any ideas?
Thanks in advance.
