Just a followup.  The problem seems to be clearly an issue of paths.  
SQLObjectStore is unable to locate the Middle package.  I'm not sure 
why.  The one thing I did notice was that although I included the line 
suggested in the Quick Start that adds the path to working application, 
this path does not show up in the sys.path on the WebKit error page.   
Maybe it shouldn't?

Another strange problem with paths is that readModelFileNamed() does not 
find Middle/Video/mkmodel/Classes.csv, even though the path is relative 
to the application.  If it use the full path it will find it, so by the 
time the request is passed to DataTable.py, it is no longer working from 
the same directory.

Just to give an idea of my file setup

Webserver/
           Webware/     "Base Install"
           ww/     "Working Directory"
           Sites/
                     url/
                               Video/
                                         Middle/
                                                   Video.py
                                                   Video.mkmodel
                                         MyServlet.py
