      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"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 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">
 <portlet>
 <portlet-name>TestRafiPortlet</portlet-name>
 <portlet-class>com.apple.TestRafiPortlet</portlet-class>

 <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/
14:05:48,024 ERROR [AbstractKernelController] Error installing to Start: name=portal:container=Portlet,id=/testrafiportlet.TestRafiPortlet state=Create

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

      Regards
