See http://www.netbeans.org/servlets/ReadMsg?list=nbj2ee&msgNo=7055 I have replicate the issue.
I think I have found the bug. It looks like your QuickieQuiz project was missing a property that the code expected to exist... resource.dir So, the q&d fix for you to make progress is to add this property definition to the EAR project's project.properties file: resource.dir=setup I will find a way to not depend on this property value... or protect against this condition.
