[Zope] Connection to MySQL in zope product

Hi, I plan to develop a product that make use of external database (MySQL). I tried to get some reference on this in internet, but to no avail. How can i do this?. I understand that with python script or dtml we need to create database connection object, and zsql method. But how do we do it from product class?. If i can get some point of reference from the net, it would be good. Thanks. __________________________________ Do you Yahoo!? Yahoo!
