Hi when I run in Python a script it runs fine, but when I put it on the extension folder of Zope and added the external method in the Zope folder where I need to start the search, this returrn an error that say " Zope Error Zope has encountered an error while publishing this resource. Error Type: IOError Error Value: [Errno 2] No such file or directory: 'chr1/CDS.htm'" The external method is in a folder called database, inside that folder are 14 folders called chr1, chr2, chr3 etc..., and inside any folder is a DTML document called CDS.htm. I already know the proble is something with the absolute path, but I don't know how I can pass this value to the external method, I really need to use those files from the ZODB because they are used to show it if somebody request it from a search in the Zcatalog. Thanks to all.
