[Zope] Import classes in External method

[Francois-Regis CHALAOUX]

Hi,

How to import classes in an External method?

I mean, where to place the module where my class is defined. I tried to put it
in "lib/python/" or "Zope-2-2-0/lib/python/Shared", or in
"/usr/lib/python1.5/" but I always got the same message : 


The errror
=======

Error Type: SystemError</STRONG><BR>
Error Value: Failed to import class myclass from module __main__ 

mycode
======

import module_of_class

def useClass(self):
    foo = module_of_class.myclass()


Bye, FR.
