I am trying to access a WSDL file directly in my Ruby. I have no  
problems accessing the WSDL and sending a request to the web service  
linked to the WSDL, but I am having a problem sending an MTOM attachment  
to the service. In my Ruby code, I specify a parameter with an object  
of type File:

“Attachment” =\> File.new()

However, when I look at the SOAP message created, the AttachedObject  
parameter is empty. Does anyone know if Ruby (specifically, SOAP4R) has  
full MTOM support? Thanks!
