I put all of the code on Google Code: http://code.google.com/p/auctionnet/
. It is a sample application I am writing for a developerWorks
tutorial on using Lift and Comet. Anyways, the code does not do
anything explicit with the database connections, just normal read/
writes. There are reads and writes in the CometActor and the other
Actor that it works with.
