I'm no zopista but I think the problem has to do with the standard error methods not being tied in directly to the object database. There are two files: /lib/python/ZPublisher/HTTPResponse.py /lib/python/OFS/Application.py that contain error pages hard coded in. you get the HTTPResponse.py code for errors like: 403: 'Forbidden', 404: 'Not Found', 405: 'Method Not Allowed', stuff like that. This error code is not parsed like normal dtml and so you can't simply replace it with: """<dtml-var standard_error_message>""" I think this is because these are standard error codes that have to do with the web server and they must work even if the object database doesn't. There must be a more detailed reason why these errors aren't connected to the db, but someone else will have to answer that one. :) jason __________________________________________________ Do You Yahoo!?

Re: [Zope] How to make two racks work under one specialist?

Hi Steve, It works! Thank you. Still there's a couple of things to be cleared. What's the use of 'otherwise' clause? And is it true that the 1st 'with' clause fails, the whole skinscript process fails (so one 'with' clause is all one skinscript can put up with)?

mynetscape-like product

Dose anyone have a product or modification to the user's page in the PTK to behave like the user customizable layout you get at sites like mynetscape.com? This would work with RSS and OCS syndication sources (as well as others). Regards, Albert Boulanger aboulanger(a)vpatch.com

There is a (low traffic) mailing list especially for Z-Commerce (to be found via zope.org) Look into its archives. You will find a thread that discusses 2 or 3 approaches. Dieter

As the message tells you, there is another Zope process accessing your "var/Data.fs". Are you sure, that your ZServer started Zope is really stopped? > python z2.py > .... > ImportError: No module named ZServer Do not start Zope in this way, use the "start" script. This script defines some environment variables (such as PYTHONHOME) before it executes "python z2.py". These environment variables are necessary to find Zope's infrastructure. Dieter

Turning on detailed logging at startup might help too... read about the -M argument in the z2.py script and read my Howto regarding "How To Track Down Hangs" at http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG "Cees de Groot" <cg(a)cdegroot.com> wrote in message news:92ghr3$jf3$1@gaia.intranet.cdegroot.com... > Dieter Maurer <dieter(a)handshake.de> said: > >Cees de Groot writes: > > > ... excessive CPU/memory consumption ... > >If you use Zope 2.2.x, you can try to access the debug tools > >in the "Control Panel".

It Seems That Zope Likes To Capitalize Just About Every Word It Gets Hold Of. Is There A Good Way To Turn This Off? I Can Think Of Some Kludges, But I'd Like To Avoid Them. Thanks. --kyler
