Team,
I had a heckuva time getting DB Connect running on Apple OS X 10.9. I got this error:
KeyError: elements
After thrashing around for a while, including installing what I thought was the latest version of Java (both runtime and JDK), I finally discovered this version of Java:
http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
I downloaded it, installed it, and the problem was solved. Hope this helps others!
Thanks, -S.
