I used your files (well, I am not using Spring, so the portlet class name is different). It worked for me: 2008-04-11 08:26:16,618 DEBUG [org.jboss.portal.core.deployment.jboss.PortletAppDeployment] Creating portlet instance PreventionsInstance 2008-04-11 08:26:16,618 DEBUG [org.jboss.portal.core.impl.model.instance.InstanceContainerImpl] Creating instance PreventionsInstance of portlet local.image.preventions My portlet even shows up on the Preventions page. What version of the Portal? Version of JBossAS? JDK version? Also, have you included all of the necessary Spring jars in the WEB-INF/lib directory? Perhaps a class that DispatcherPortlet relies on is missing. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143475#...
