Hello, I am trying to get Zope to connect to a MySQL database. I am having trouble tracking down why it will not connect. The error message on the web page produces only six hits in Google; http://www.google.com/search?q=The+database+connection +MySQL_database_connection+cannot+be +found.&start=0&ie=utf-8&oe=utf-8&client=firefox&rls=org.mozilla:en-US:unofficial Here is the Zope debugging error message from zopectl fg; (Complete debugging information is below.) ImportError: cannot import name ImmutableSet Does anyone have any recommendations on how I can solve this? Thanks very much, Jeremiah Complete debugging output: -------------------------------- /usr/local/www/zopeserver/bin/runzope -X debug-mode=on 2006-06-14 16:14:53 INFO ZServer HTTP server started at Wed Jun 14 16:14:53 2006 Hostname: 0.0.0.0 Port: 8080 2006-06-14 16:14:53 INFO Zope Set effective user to "zope" 2006-06-14 16:14:53 INFO DocFinderTab Applied patch version 0.5.2. 2006-06-14 16:14:53 INFO IngeniWeb NOTICE global_symbols.py:22:Wed Jun 14 16:14:53 2006: 'Starting /usr/local/www/zopeserver/Products/GroupUserFolder at 4 debug level' /usr/local/www/Zope28/lib/python/OFS/Application.py:695: DeprecationWarning: Non-ASCII character '\xe1' in file /usr/local/www/zopeserver/Products/Localizer/__init__.py on line 1, but no encoding declared;
