Just had the same error and found the answer. It's because you do not overide the right doview method :-) (public!=protected); you just add a new one... beside it seem the default for JBossPortlet.doView is to send a PortletException (when geneiric do nothing...) btw which portlet container do you use ? with jbossportal you don't have to include additional jar to your war/ear (with netbean library->properties-> uncheck package :-) ) sample : | public class MenuPortlet extends JBossPortlet { | protected void doView(JBossRenderRequest request, JBossRenderResponse response) throws PortletException, PortletSecurityException, IOException { | System.out.println(">>>>> ok doview"); | response.setContentType("text/html"); | PortletRequestDispatcher dispatcher = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/Menu_view.jsp"); | dispatcher.include(request, response); | } | } | check your portlet.xml for correct mode ; here i only use view A+ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4150729#...
