Maybe you have wrote an error for the class of your portlet. Check com.PortletDefinitiion in portlet.xml: | <portlet> | <portlet-name>dummy-HeaderPortlet</portlet-name> | <portlet-class>com.PortletDefinitiion</portlet-class> | <supports> | <mime-type>text/html</mime-type> | <portlet-mode>VIEW</portlet-mode> | </supports> | <portlet-info> | <title>Header Portlet</title> | </portlet-info> | </portlet> | It seems an error.
