Hi, I have copied the folder of the ZJetDA-0.1.1 product on the directory "C:\Zope\2.10,1 \ Zope \ lib \ python \ Products" and restarted Zope. If I go in the Control panel -->Product management, I can visualize it, but how can I use it? how to create an instance of it in my project… Probably I didn't understand How to add a Product... I hope in your aid….Thanks.. Naviga e telefona senza limiti con Tiscali Scopri le promozioni Tiscali adsl: navighi e telefoni senza canone Telecom http://abbonati.tiscali.it/adsl/
