Hi all I have a COM component that I need to access from Zope. I must either put this component into a session so that I can carry it around wherever the user goes OR I must put it into a global object store where I can extract it whenever I need it. My problem is: making a class according to Zope's persitence rules does not work as I get a cPickle.Pickling error (I guess a COM object cannot be pickled). Saving the creation parameters and instantiating the COM object every time I need it is really not going to work as the COM object connects to a remove server and the connection time can be lengthy. I must store the object in something where it will be accessible for the lifetime of the Zope service (or some other arbitrary timeout). Will the following type of solution work (I hate global variables!) or is that basically all I can do: In my external method: objectStore = {} def GetObject(self,name): global objectStore return objectStore[name] def SetObject(self, name, params): global objectStore objectStore[name] = myComObjectWrapper(params) #creates the com object How will namespaces, module namespaces and multiple threads affect the accessibility and/or contents of objectStore? Any help, pointers, etc. would be greatly appreciated. Regards Etienne
