I'm following Ch. 12 in the reference guide to add admin mode to portlet. When I deploy the portlet, I get the following error: 2009-03-13 16:50:08,131 ERROR [org.jboss.deployment.MainDeployer] Could not start deployment: file:/E:/Dev/Tools/jboss-portal-2.7.1/server/default/tmp/deploy/tmp9050440818682779072FlickrPortlet-0.0.1-exp.war/WEB-INF/ java.lang.IllegalArgumentException: Mode cannot be null at org.jboss.portal.Mode.(Mode.java:70) at org.jboss.portal.Mode.create(Mode.java:159) at org.jboss.portal.Mode.create(Mode.java:126) at org.jboss.portal.portlet.impl.info.ContainerInfoBuilder.build(ContainerInfoBuilder.java:456) at org.jboss.portal.portlet.impl.info.ContainerInfoBuilder.build(ContainerInfoBuilder.java:368) at org.jboss.portal.core.impl.portlet.info.CoreInfoBuilder.build(CoreInfoBuilder.java:111) at org.jboss.portal.portlet.deployment.jboss.PortletAppDeployment.start(PortletAppDeployment.java:169) ......... I added the following two lines to portlet.xml: <portlet-mode>admin</portlet-mode> <custom-portlet-mode> admin </custom-portlet-mode> Any help would be appreciated.
