Hi, all. 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.
