I have searched the documentation and zope.org but am having trouble finding the requirements for using Refresh (other than I know that the product directory has to have a refresh.txt file in it). Is it required that the product use the "new" method of product initialization, i.e.: def initialize(context): context.registerClass( etc. Thanks, Bill ---------- "The commandments of the LORD are right, bringing joy to the heart.

Are you working with products that use the old style [of product initialization]? Are they still around? ;-)

I'm developing a Zope Database Adapter (DA) for the SQLite (http://www.hwaci.com/sw/sqlite) embedded database. Although a DA isn't a Product in the usual sense, the front-end is registered like a product and has a Management interface. I've noticed that existing DA's that I'm studying for reference, including DCOracle2, don't use the "new" method of Product initialization / registration. Are DA's considered "monkey patch" products? Is it possible to use the Refresh feature during development of a DA? Thanks, Bill http://pysqlite.sourceforge.net ---------- "The commandments of the LORD are right, bringing joy to the heart.

I often read that for "security reasons" one should use Apache or Squid in front of Zope. So simple question: why? Isn`t the Medusa Webserver secure that all? And why does zope.org uses Apache? I would like to understand the reasons behind this decision. I thought it was for loadbalancing only - but now there is ZEO - so why using Apache or Squid? Buelent

This happens when you create references to the product outside the product. Most Zope products don't need to. Those that do (like CallProfiler and other monkey patch products) should not be considered refreshable.

It happens to me also. I have a product who uses as a base class something defined in another product. When I refresh the second product, I have to refresh the first one afterwards. Florent -- Florent Guillaume, Nuxeo (Paris, France) +33 1 40 33 79 87 http://nuxeo.com mailto:fg@nuxeo.com
