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.PortletContainerImpl.portletLoad(PortletContainerImpl.java:218)

My configuration files are:
webapps/pluto/WEB-INF/data/Portletentityregistry.xml:

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