Portletize ZK Application on PLUTO 1.0.1

[Antonio Iossa <an...@enterpriseda.com>]

Hi all, 
 
I would "portletize" a zk application in pluto (ver. 1.0.1 for project 
constraints). 
I follow the procedure specified in the zkDevGuide and zkDevRef, but I 
get the following error (tomcat log files): 
 
org.apache.pluto.portalImpl.services.log.LoggerImpl error 
GRAVE: Error in Portlet 
java.lang.NullPointerException

org.apache.pluto.invoker.impl.PortletInvokerImpl.invoke(PortletInvokerImpl.java:109)

org.apache.pluto.PortletContainerImpl.portletLoad(PortletContainerImpl.java:218)

My configuration files are:

<application id="8">

Any idea of what is the problem? 
 
Thank you in advance,
