      I am trying to install a new Portlet into JBoss Portal. When I do, I get the following error:

      2006-10-05 16:23:34,281 DEBUG [org.jboss.portal.core.deployment.jboss.PortletAppDeployment] Creating portlet instance WebVideoInstance

      Here are my descriptor files:

      portlet.xml 
      <?xml version="1.0"?>

 </instance>
 </deployment>
</deployments>


      WebVideo-object.xml 
      <?xml version="1.0" encoding="UTF-8"?>
<deployments>
 <deployment>

 <instance-ref>WebVideoInstance</instance-ref>
 <region>center</region>
 <height>0</height>
 </window>
 </page>
 </deployment>
</deployments>


      Any help would be appreciated.
      Ps. This is my first attempt at portlets.
