Hi Ausum, ok I'll get more into detail even if some problems are already solved. I want to upload object's with properties of different meta_types from a local Zope to a remote Zope just via HTTP (no zexp etc. cause I have no access and cannot add any Products to the remote Zope) :-( I will do it with an external method based on uploadfile.py @ zope-cookbook by pieterb 1. problem: I managed to upload files, folder, ... with title just python scripts don't work (I'll show the code later...) 2. problem: I cannot add other properties upto now Can anybody give some hints? -- many thanks for your replies, Elena the relevant codesnippets: import urllib ..... # use authentication and set the user agent urllib._urlopener = MyUrlOpener() ..... if objectType != 'Folder': objectSource = object.read() ### I get the script-body with bindings and params if objectType == 'Script (Python)': params = urllib.urlencode({'id': objectId, 'file':objectSource}) ##### this doesn't work else: params = urllib.urlencode({'id': objectId, 'title':objectTitle, 'file':objectSource}) ##### this works nicely myAction = actionDict[objectType] callURL = '/'.join([myHost, objPath, myAction]) ## if objectType == 'Script (Python)' myAction is 'manage_addPythonScript' # send the file to zope f=urllib.urlopen(callURL, params) ##### this works nicely exept for 'Script (Python)' type # add properties callURL = '/'.join([myHost, objPath, 'manage_addProperty']) for prop in object.propertyIds(): if prop != 'title' or objectType != 'Script (Python)': ### title exists already, scripts don't have properties propValue = object.getProperty(prop) propType = object.getPropertyType(prop) ### up to here it works #### but the upload of the properties does not work params = urllib.urlencode({'id': prop, 'value':propValue, 'type':propType}) #urllib._urlopener = MyUrlOpener() ### I tried to set the opener again, but no change f=urllib.urlopen(callURL, params)
