I can run that app with no problems in my environment, and as you can see, there isn't much to it. A difference in our environments could certainly be the culprit. All I did to install the portal was to dump the portal .sar directory into my deploy directory, and I also copied the portal-hsqldb-ds.xml file from the /setup directory into my deploy directory as well. But that's all I did to install the portal before deploying my test app. You may have to keep experimenting... Maybe back up your current portal directory and try a fresh installation; just to make sure everything is clean.
