Hi all,
I'm trying the portlet tutorial found on jahia.org.
I've no problem to deploy my helloworld-portlet.
But when I add it on my page, instead of printing "Hello world", I get a
ClassCastException, with the following stacktrace :
ERROR [org.apache.jetspeed.factory.JetspeedPortletFactory] - Cannot
create Portlet instance
com.bchaffangeon.sample.portlet.HelloWorldPortlet for Portlet
Application HelloWorldPortlet
java.lang.ClassCastException:
com.bchaffangeon.sample.portlet.HelloWorldPortlet
