That was absolutely true! In fact, removing the "factory"-parameter made 
it work after all.

This was an excellent tip. I used an untouched, local Tomcat 
installation on my laptop, cleaned the logs, and deployed my faulty 
project and looked into the "extra junk". There I found the following in 
between hibernate initialization and configuration process:

     org.hibernate.cfg.Configuration - Configured SessionFactory: null

That gave it away!

Thanks, Chris, for giving me the direction!

Have a nice weekend!
