You are missing Zope init/configuration (which initialize all Zope Products and python paths to them).
I use this minimal script: import sys zope_home='/opt/pperegri/builds/F2.12/opt/Zope-2.8.6-final' instance_home='/opt/pperegri/builds/F2.12/instances/zope_rw' sys.path.append('%s/lib/python'%zope_home) import Zope2 Zope2.configure('%s/etc/zcmd.conf'%instance_home) app=Zope2.app() The zcmd.conf file is a copy of my zope.conf where I remove all the zservers and also, as you are using zeo, you need to use a different client name in the <zeo> section to make sure the cache file is different. This is just for some basic testing, as you will need to kill the script to terminate the python interpreter (CTRL-D won't make it) because of some Zope backgroup threads. Pascal -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Richard Jennings Envoyé : mercredi 7 juin 2006 11:53 À : zodb-dev@zope.org Objet : [ZODB-Dev] Zeo: connection problem Hi, I have a Zope2.7.2/Zeo2.2.2 instance running, using the standard zope.conf & zeo.conf settings (exception: port=8081) and it works fine. I want read-only access to the instance zodb to read site object properties. In a test script, I have used the apparently classic pattern, shown below: addr = ('localhost', 8081) storage = ClientStorage.ClientStorage(addr) db = DB(storage) conn = db.open() root = conn.root() app = root['Application'] This results in the exception shown below. The pattern is so basic and simple, it seems difficult to make a mistake, but I am! Can someone tell me what?
