[Zope] SSL Ioan's Tutorial problem

[Zanotti Michele]

Hi all,
I have tried to follow Ioan's instructions in Zope and SSL tutorial, but
when I start my Zope 2.5 on win2k I have this error:
2002-01-30T08:56:27 PANIC(300) Z2 sTARTUP EXCEPTION
Traceback (innermost last):
 File G:\Zophelopment\z2s.py, line 668, in ?
 File G:\ZOPHEL~1\ZServer\HTTPServer.py, line 320, in __init__
 File G:\ZOPHEL~1\ZServer\medusa\http_server.py, line 562, in __init__
 File G:\ZOPHEL~1\ZServer\HTTPServer.py, line 334, in create_socket
TypeError: unbound method create_socket() must be called with instance as
first argument
Can anyone explain to me my mistakes? 
Thank you
Michele
P.s. Thanks all yesterday answered my question on Zope and Oracle Ifs.
