Difference between portlet-ref and component-ref - portlet i

[dhoward0000]

I'm trying to figure out why with the below configuration, only the TestPortletInstance30 instance will get created. Neither instance in the portlet-instances.xml is generated. Any ideas?


jboss-app.xml:

<jboss-app>
 <app-name>appname</app-name>
</jboss-app>

portlet-instances.xml:

<deployment>
 <instance>
 <instance-id>TestPortletInstance10</instance-id>
 <portlet-ref>appname.TestPortlet</portlet-ref>
 </instance>
 </deployment>

<deployment>
 <instance>
 <instance-id>TestPortletInstance20</instance-id>
 <portlet-ref>TestPortlet</portlet-ref>
 </instance>
 </deployment>

myapp-object.xml:

<deployment>
 <parent-ref/>
 <if-exists>overwrite</if-exists>
 <instance>
 <instance-name>TestPortletInstance30</instance-name>
 <component-ref>appname.TestPortlet</component-ref>
 </instance>
 </deployment>

Thanks.
