Hi, I have a ZClass-based product, say ZClassTest. There is a ZClass named "ZClass1" in that product folder. There is another ZClass named "ZClass2" within the ZClass1. i.e. ZClass2 is a method of ZClass1. The problem is that I can access the content of ZClass2 by WebDAV. But failed to access the same content by FTP. The error message says that there is not such file or directory. that is : ftp://host/Control_Panel/Products/ZClassTest/ZClass1/propertysheets/methods/ZClass2 is fine.( return a list with "propertyshees/methods") but ftp://host/Control_Panel/Products/ZClassTest/ZClass1/propertysheets/methods/ZClass2/propertysheets/methods is broken. ( error 505) I noticed that actually the zope responses an extra space behind "ZClass2", that is ftp://host/Control_Panel/Products/ZClassTest/ZClass1/propertysheets/methods/ZClass2 /propertysheets/methods I hacked the zope code () and strip that extra space off. But the trouble is still there. Any suggestion is highly appreciated. Iap, Singuan
