How can I determine 'My Product Name'? My class named 'MyClass'. It be
located in dir ../Python/Products/MyProject/.

If I try use below
context.manage_addProduct['MyClass'].manage_addMyClass(id,None)

Zope write:
"An error was encountered while publishing this resource.
Error Type: AttributeError
Error Value: MyClass"

 Thanks and kind regards
