[jboss-user] [JBoss Portal] - Cannot install new Portlet (failes to create instance)

[kc7bfi]

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

  |          </window>

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