I got stuck implementing the examples in "A Technical Introduction to Object Publishing with Zope" <http://www.zope.org/Documentation/Reference/ObjectPublishingIntro> with the stand-alone ZPublisher. In the "guestbook.py" example, what should be the URL invoked to show the form? The module is called guestbook.py, the class is GuestBook and the method is defined as "def guestbookForm(self)". I've been succesful installing and runnig the previous examples but in this case I don't know what should be the first URL called to run the Guestobook application. If I type: <http://localhost/cgi-bin/GuestBook.zcgi/GuestBook> I get this: -- GuestBook.GuestBook -- (The Guesbook __repr__?) If I type: <http://localhost/cgi-bin/GuestBook.zcgi/GuestBook/guestbookForm> I get: -- Sorry, an error occurred. Traceback (innermost last): File C:\Zope\lib\python\ZPublisher\Publish.py, line 879, in publish_module File C:\Zope\lib\python\ZPublisher\Publish.py, line 595, in publish (Info: /GuestBook/guestbookForm) TypeError: unbound method must be called with class instance 1st argument -- Thanks for any help.
