Resolved.

My problem was that the contextName init-parameter, in web.xml, was wrong.
It has to be the same name as the war file deployed.

This can be many thing ranging from a fault in Jahia to an uncompilable jsp. You need to explicitly call for a stack trace in your portlet class. Similar to: 

catch (Exception ex_{
         ex.printStackTrace();
}

that should give you some information on the Jahia.log
Hum, actually my code is very simple at this time (based on the tutorial) : 

public void doView(RenderRequest request, RenderResponse response) {
           try {
                  response.setContentType("text/html");
                  PrintWriter out = response.getWriter();
                  PortletURL url = response.createRenderURL();
                  PortletURL actionURL = response.createActionURL();
                  out.print("Hello world!");
           }
           catch (Exception ex) {
                  ex.printStackTrace();
           }
    }

So I'm not using a jsp yet.

I would imagine the problem is that you are including a portlet.jar in your com.bchaffangeon.sample.portlet.HelloWorldPortlet.war. Including the jar is not permitted 
Thanks for your response.
You're right there was 2 .jar in /lib.
I removed these and now I've the following message in Jahia : "The requested resource (/container) is not available". 
But there are no messages in logs...

Do you have an idea ?

Thanks in advance

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 at org.apache.jetspeed.factory.JetspeedPortletFactory.getPortletInstance(JetspeedPortletFactory.java:204) at org.apache.jetspeed.container.invoker.ServletPortletInvoker.invoke(ServletPortletInvoker.java:190) at org.apache.jetspeed.container.invoker.ServletPortletInvoker.render(ServletPortletInvoker.java:126) at org.apache.pluto.PortletContainerImpl.renderPortlet(PortletContainerImpl.java:119) at org.apache.jetspeed.container.JetspeedPortletContainerWrapper.renderPortlet(JetspeedPortletContainerWrapper.java:120) at org.apache.jetspeed.aggregator.impl.RenderingJobImpl.execute(RenderingJobImpl.java:121) at org.apache.jetspeed.aggregator.impl.PortletRendererImpl.renderNow(PortletRendererImpl.java:120) at org.apache.jetspeed.aggregator.impl.PortletAggregatorImpl.build(PortletAggregatorImpl.java:84) at org.apache.jetspeed.aggregator.PortletValve.invoke(PortletValve.java:46) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.apache.jetspeed.container.ContainerValve.invoke(ContainerValve.java:76) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.jahia.services.applications.JahiaSecurityValveImpl.invoke(JahiaSecurityValveImpl.java:82) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.apache.jetspeed.container.url.impl.PortalURLValveImpl.invoke(PortalURLValveImpl.java:67) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.jahia.services.applications.JahiaProfilerValveImpl.invoke(JahiaProfilerValveImpl.java:67) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.apache.jetspeed.capabilities.impl.CapabilityValveImpl.invoke(CapabilityValveImpl.java:128) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.jahia.portal.localization.LocalizationValveImpl.invoke(LocalizationValveImpl.java:118) at org.apache.jetspeed.pipeline.JetspeedPipeline$Invocation.invokeNext(JetspeedPipeline.java:166) at org.apache.jetspeed.pipeline.JetspeedPipeline.invoke(JetspeedPipeline.java:145) at org.apache.jetspeed.engine.JetspeedEngine.service(JetspeedEngine.java:214) at org.jahia.bin.JahiaJetspeedServlet.doGet(JahiaJetspeedServlet.java:235)
