[jboss-user] [JBoss Portal] - Failed to create instance error

I have an application packaged in a .war file, deployed to JBoss Portal version 2.4 (App server version 4.0.5GA). I got the following error: 10:32:50,767 WARN  [PortletAppDeployment] Failed to create instance MyWebsitesPortletAgentInstance of portlet .MyWebsitesPortlet because portlet .MyWebsitesPortlet is not available. The strange thing is that I don't understand where the "." before the portlet name "MyWebsitesPortlet" in the error message comes from. When I define the portlet name, I didn't put in any ".". In a browser, when I go to the page where this portlet is supposed to show up, it says that "object not found MyWebsitesPortletAgentInstance". Any ideas on how to fix this are appreciated. Thanks.   -Andrew ------------------------------------------------------------ The xml configuration files are as follows: portlet.xml <?xml version="1.0" encoding="UTF-8"?> <portlet-app xmlns=" http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_1_0.xsd"     xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance 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 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>MyWebsitesPortlet</portlet-name>         <portlet-class>mydomain.MyWebsitesPortlet</portlet-class>         <init-param>             <name>default-view</name>             <value>/WEB-INF/jsp/index.jsp</value>         </init-param>         <supports>             <mime-type>text/html</mime-type>             <portlet-mode>VIEW</portlet-mode>         </supports>         <supported-locale>en</supported-locale>         <supported-locale>fr</supported-locale>         <resource-bundle>labels</resource-bundle>         <portlet-info>             <title>My Websites Portlet</title>         </portlet-info>         <portlet-preferences>             <preference>                 <name>MyWebsiteType</name>                 <value>AGENT</value>             </preference>         </portlet-preferences>     </portlet>     <user-attribute>         <name>user.name.given</name>     </user-attribute>     <user-attribute>         <name>user.name.family</name>     </user-attribute>     <user-attribute>         <name>user.name.middle</name>     </user-attribute>     <user-attribute>         <name>portal.user.locale</name>     </user-attribute> </portlet-app> --------------- portlet-instances.xml <?xml version="1.0" standalone="yes"?> <deployments>    <deployment>       <instance>          <instance-id>MyWebsitesPortletAgentInstance</instance-id>          <portlet-ref>MyWebsitesPortlet</portlet-ref>             <preferences>                 <preference>                 <name>MyWebsiteType</name>                 <value>AGENT</value>                 </preference>             </preferences>       </instance>    </deployment>   </deployments> ----------------- MyWebsites-object.xml <?xml version="1.0" encoding="UTF-8"?> <deployments>    <deployment>       <if-exists>overwrite</if-exists>       <parent-ref>default.default</parent-ref>       <window>          <window-name>MyWebsitesPortletAgent</window-name>          <instance-ref>MyWebsitesPortletAgentInstance</instance-ref>          <region>center</region>          <height>0</height>       </window>    </deployment>   </deployments> -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544891#544891] Start a new discussion in JBoss Portal at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
