Hi – I’ve got a class called SF::SOAP that gets defined at  
/lib/wsdl/sandbox/defaultDriver.rb  
It is defined like:

module SF  
class SOAP  
# …  
end  
end

How do I include this in my Rails app so that I can (for instance) call  
SF::SOAP.new without getting an unintitialised constant (for SF) error?  
I’ve tried direct requires, adding to the config.load\_paths in the  
environment files, adding to the $: array, all to no avail.  
I did something similar years ago, but I’m damn’ed if I can remember  
how, so any help would be very gratefully received.  
Cheers,  
Doug.

Rails’ dependency loading mechanism will automatically pick up SF::Soap  
if it is in the following location: /lib/sf/soap.rb

Cheers – I was being a total spoon.  
All I needed to do was to require it normally – thought I’d tried that,  
but must have prepended it with a slash out of habit the first time, or  
something.  
Thanks,  
Doug.
