Hi, I have installed Zope 2.1.6 in Red Hat Linux 6.2 box. I followed the How-To installing and Upgrading Zope 2.x. No problems expect when I try to run a method of a Python Class that is used as Z base class. My method works fine with the python interpreter. However when I tried it within Zope i get Error Value: [Errno 13] Permission denied I have been trying many things to solve this problem (changing permissions of the directory i want to accesss to, of the module, ...). What is the right thing to do? It has surely more to do with the Unix permissions but i don't know to solve this problem. Here is what i have done. #### My base class: #### in /usr/local/zope/lib/python/Products/BaseStore/BaseStore.py #### -rw-rw-r-- 1 root root 1273 Apr 14 15:37 BaseStore.py class BaseItem: def import_properties(self, path): """Import properties and other attributes from a file system folder. path is the folder path. """ file_names = os.listdir(path) #... ------------^--------the guilty #etc. #### in Zope: B is an instance of ZClass which subclasses CatalogAware, BaseItem, ObjectManager and Folder. #### in the same folder as B i have a test method with: <dtml-var "B.import_properties('/home/oscar/xenata/mz')"> .... #### When I try to view my test Zope method i get: [Zope] Zope Error Zope has encountered an error while publishing this resource.
