    Porlet Tutorial WebWork 2.2

    Ben Sisson Newbie

      I created the portlet using Eclipse that was specified in Portlet Tutorial WebWork 2.2. I zipped up the directories into a war file and dropped them into the deploy directory within my jboss-portal-2.6.6.GA server. I then get the following message indicating that the deployment failed. I already deployed a portlet using the QuickStart Guide for the server with no issue and the formats look similar. I would apprecicate any help.

      10:48:32,899 WARN [PortletAppDeployment] Failed to create instance MyPortletIns
      tance of portlet MyPortlet.MyPortlet because portlet MyPortlet.MyPortlet is not
      available

      Thanks...

          Please post the contents of portlet.xml, porlte-instances.xml and *-object.xml (all are in the WEB-INF directory of the WAR).

          Remember to enclose your XML text in UBBCode "code" tags - you can do this by selecting the XML text and clicking the Code button above the editor window. Also, click the Preview button to ensure that the formatting is correct and the XML text shows up before posting.

            I have included the code for portlet.xml and MyPortlet-object.xml. However, there is no portlet-instances.xml code in this tutorial or I'm not sure which file it would be in. The other xml files that exist under WEB-INF are jboss-app.xml, jboss-portlet.xml, and web.xml.

            The tutorial is located at the following site: http://struts.apache.org/2.0.11/docs/portlet-tutorial-webwork-22.html

              You need to create a portlet-instanxes.xml file and move the 'instance' entry from MyPortlet-object.xml to there. Thus portlet-instances.xml should contain:

              <deployments>
               <deployment>
               <instance>
               <instance-id>MyPortletInstance</instance-id>
               <portlet-ref>MyPortlet</portlet-ref>
               </instance>
               </deployment>
              </deployments>


              and MyPortlet-object.xml should contain:

              <deployments>
               <deployment>
               <if-exists>overwrite</if-exists>
               <parent-ref>default</parent-ref>
               <properties />
               <page>
               <page-name>MyPortlet Tutorial</page-name>
               <properties />
               <window>
               <window-name>MyPortletWindow</window-name>
               <instance-ref>MyPortletInstance</instance-ref>
               <region>center</region>
               <height>0</height>
               </window>
               </page>
               </deployment>
              </deployments>
