RSSPortlet Exception!

rodenbaugh Jan 20, 2006 6:31 PM

I have installed JBoss Portal 2.2.0/JBoss 4.0.3SP1 and have attempted to deploy the community-sanctioned RSS Portlet. Here is the exception trace immediately after deployment:

The portal functions normally prior to the deployment. The management portlet does show the portlet in the instance list, but I can't navigate to it--each attempt repeats this exception.

Help?

Hello,

I'm having the same problem installing RSS Portlet. If someone know how to fix this - please let me know.

Thanks,

Apparently, no one pays attention to this board. I looked at the RSS portlet itself and it's not 2.2 portal compliant. It uses the old -instances.xml and -portlet.xml instead of -object.xml. When I converted it, re-WAR'd it, and then deployed, things worked much better.

Try that,

I am creating a new RSS news portlet and will have it up by the end of Feb. It will also be bundled with Portal 2.4.
