I must be missing something obvious but I am at a loss for what it is. I am attempting to include a Python module ( the module at http://python-dsv.sourceforge.net/) in my Zope 2.6.2 Win2000 site so that it can be used by Zope python scripts. I have been following ( at least as far as I can tell) the instructions provided in the "README.txt" of the "PythonScripts" product at "lib/python/Products/PythonScripts/", namely to create a new Product directory, add the module, and an "__init__.py" file according to the instructions, restart the server. All appears well there. I then attempt to import the module in a Python script( which appears to work). My first attempt to use it though results in authentication requests and eventually ( after using correct authentication for the admin) the following message: "System Unavailable This site is currently experiencing technical difficulties. Please contact the site administrator for more information. For additional technical information, please refer to the HTML source for this page. Thank you for your patience. Error type: Unauthorized Error value: The container has no security assertions. Access to 'organizeIntoLines' of (module 'DSV.DSV' from 'F:\WEBSIT~1\lib\python\Products\DSV\DSV.py') denied." I am guessing it is something simple I have overlooked but I am not sure where to go next.
