...

I have trival class on Python:

manage_addMin_allForm=DTMLFile('dtml\manage_addMin_allForm',globals()) class min_all(SimpleItem.SimpleItem): ...

How I can show & exec manage_addMin_allForm on external Python script?

Why do you want to do this?

...

I can use RESPONSE.redirect('manage_addProduct/Minimal/manage_addMin_allForm'). But I want to do some like this: self.manage_addMin_allForm().

self.manage_addProduct['Minimal'].manage_addMin_allForm(self,self.REQUEST)

If I use this code Nothing occurs.

Why are you using DTML?!

I want to create class which will allow adds objects of any class through my own interface. For example: user click on button "Add Min_all" on dtml form, and manage_addMin_allForm is shown. User input data in manage_addMin_allForm and click "Add" button on manage_addMin_allForm. After that object of Min_all with necessary values of attributes will be added to ZODB.
