Are there any licencesd products like Zope?
For Instance:
Enterprise Java Beans WebLogic Server Persistance Vignette StoryServer

I'm not sure quite what your mean by 'licensed'. Zope is licensed software under the Zope Public License 1.0. Do you mean commercial? -Michel

I have been trying to make my own Zope product and I am sorry to say that I have found it to be a daunting task. Does anyone know where I can go to get better info? Is there anyone who has created a product who is not working for Digital Creations? Debugging facilities are non-existent and documentation is esoteric. Should I say goodbye to Zope forever?
For years the Apache module API was difficult to use and undocumented. Would you have said goodbye to Apache then?
There are lots of new docs on the horizon. Amos and Pam are coordinating the new Zope Developers Guide, and soon there will be a *very* exciting announcment on Zope developer documentation that will be available in about six months.
This has been a long standing problem, my first Zope app was when Zope was Principia and the source code was encrypted bytecode, the only way to figure out the API then was to bug Jim and use black-boxing techniques in a python interpreter (and yes, I had to walk uphill both ways to work every day too). Now that the source code is available and you get to know your way around, documentation is almost superfulous (that's what we tell ourselves at least, we realize that this is an unacceptable situation for most).
There are two extrememly useful debugging tools, one is even documented. The Zope debugger and the medusa monitor client. The debugger lets you simulate a REQUEST to Zope and to enter the Python debugger at certain key breakpoints in the request path.
cd to lib/python (make sure Zope is NOT running):
[michel@aldous python]$ python1.5.2 Python 1.5.2 (#1, Apr 14 1999, 10:34:26) [GCC 2.7.2.3] on linux2 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
import Zope, ZPublisher ZPublisher.Zope('')
... output from a request for '' which is the same as http://machine:port/
ZPublisher.Zope('/manage', u='superuser:123', d=1)
... 'd=1' means enter the debugger immediatly, u='' is the userid and password to access the request (if it needs one). More information on the pyhton debugger can be found at http://www.python.org
ZPublisher.Zope('', t=1)
... runs the requst for '' 1000 times and prints the average time it takes to complete one request.
Note that the above is for Zope 2.0 ONLY. If you are using Zope 1.10.2 it works ALMOST the same, except instead of saying 'Zope' everywhere, you say 'Main' like:
import Main, ZPublisher ZPublisher.Main('')
The medusa monitor client put you at a python prompt, RIGHT INSIDE ZOPE. This is so incredibly useful that sometimes I break into Tears Of Joy (tm) that Sam implimented this.
Go to your top level directory and cd ZServer/medusa:
[michel@aldous medusa]$ python1.5.2 monitor_client.py localhost 9999 Enter Password: XXXXX

import Zope x = Zope.app() x <Application instance at 86dc130> x.cat <ZCatalog instance at 86e90a0>
You are sitting right inside Zope. x=Zope.app() makes a connection to the database, at which point 'x' is the 'root folder' of your Zope install.
(ZDP guys, you might want to put this on the site)
