Hi Christian,
Looks like a hierarchical ClassLoader issue. Try moving Velocity jar
from shared location to WEB-INF/lib

Hello!
Currently after updating some jars and mysql it looks like Cayenne
not longer is working. I get a "strange" Exception where I can't
see what the actual problem is. Perhaps somebody on this list can
give me a short hint?
