    Failed to create instance of Portlet.

    Mohamed Rafi Sirajuddeen Newbie

      Hi,

      I am trying to install a new portlet into the JBoss Portal. However, when I try to deploy it, I get the following error:

      14:05:48,123 WARN [PortletAppDeployment] Failed to create instance TestRafiPortletInstance of portlet /testrafiportlet.TestRafiPortlet because portlet /testrafiportlet.TestRafiPortlet is not available
      14:05:48,372 INFO [Http11BaseProtocol] Starting Coyote HTTP/1.1 on http-0.0.0.0-8080
      



      Following are the descriptor files and their contents which I have used.

      portlet-instances.xml

      <deployments>
       <deployment>
      
       <instance>
       <instance-id>TestRafiPortletInstance</instance-id>
       <portlet-ref>TestRafiPortlet</portlet-ref>
       </instance>
       </deployment>
      </deployments>
      
      


      portlet.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd"

       xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd"
       version="1.0">

       <mime-type>text/html</mime-type>
       <portlet-mode>VIEW</portlet-mode>
       </supports>
       <portlet-info>
       <title>Test Rafi Portlet</title>
       </portlet-info>
       </portlet>
      </portlet-app>
      
      


      testrafi-object.xml

      <deployments>
       <deployment>
       <if-exists>overwrite</if-exists>
       <parent-ref>default.default</parent-ref>
       <window>
       <window-name>TestRafiPortletWindow</window-name>
       <instance-ref>TestRafiPortletInstance</instance-ref>
       <region>center</region>
       <height>1</height>
       </window>
       </deployment>
      </deployments>
      


      The exception which is getting thrown is:

      14:05:47,307 INFO [TomcatDeployer] deploy, ctxPath=/testrafiportlet, warUrl=.../deploy/testrafiportlet.war/

      Any ideas on what am I missing here, and how to get it fixed?
