I decided it was time to move up to Jetspeed though, and so today downloaded the installer and ran through the process of unpacking the jar and letting ant install.
The portal did start up. Just about all of the war files unpacked and installed, but not j2-admin. When I went to the page I found several portlets with messages like
Failed to retrieve Portlet Definition for j2-admin::LocaleSelectorFailed to retrieve Portlet Definition for j2-admin::LocaleSelectorjava.lang.IllegalArgumentException: Cannot pass a null PortletDefinition to a PortletEntity.Failed to retrieve Portlet Definition for j2-admin::LocaleSelectorFailed to retrieve Portlet Definition for j2-admin::LocaleSelector
I've tried googling around for answers, but there don't seem to be many people running into this exact problem. Questions near to this have been asked on this forum, but with no response.
Any chance that someone else is messing around with this right now and happens to know what the problem here is though?
This all worked right out of the box when I had fixed the problem mentioned above. I was also able to get my own hello world portlet working and an example of portlet-to-portlet communication with a third party jar.
