CR,
  Terrific!  I had briefly wondered if that was causing the issue but 
thank you for checking it for me.  I will continue pursue the issue by 
verifying the SOAP standard and if it is supposedly case-insensitive 
I'll open a ticket with 'soap4r'.

Again thank you very much.

Chris

p.s. Incidentally  I have another solution which I just completed before 
checking the forum here.  It simply involves not using the WSDLDriver 
and instead just using 'soap/driver' which I believe is the RPC driver. 
I've attached that code for completeness.

#!/usr/bin/env ruby

require 'soap/driver'

wsdl_url = "http://usint.skire.com/ws/services/mainservice?WSDL"
namespace = "http://general.service.webservices.messenger.skire.com"

soap = SOAP::Driver.new(nil, nil, namespace, wsdl_url)

soap.wiredump_file_base="soapresult"

soap.addMethodWithSOAPAction('getBPList', namespace, "shortName", 
"authCode", "projectNumber", "bpName", "nil", "nil", "nil")

result = soap.getBPList("one", "two", "three", "four", '', '', '')

puts result.xmlcontents
