[Zope-dev] Need help

I have to use a logging framework in my zope product. The logging framework makes it mandatory to use the same object instance to fire various logging calls (like log start, log end). I want to store the object instance somewhere so that I can use it from any module in my zope product. I tried to store it in context._ProductContext__app. There are two patch classes of httprequest and httpresponse inside which the context is not available. How do I do this in Zope-2.8.8 Thanks Roopesh
