Calling ASP C# web service from Ruby?

[mmm]

Hi, I'm new to Ruby and would appreciate some suggestions....I'm
attempting to call a soap web service written in C# and hosted w/ IIS
from Ruby.

Does anyone know of a simple code segment that actually does this? The
AWS icd example that does this is giving lots of errors (c:/program
files/ruby/lib/ruby/1.8/xsd/charset.rb:97:in `encoding_conv': Converter
not found: UTF8 -> SJIS (XSD::Charset::CharsetConversionError) which I
do not understand and can't figure out how to resolve...

The code i've tried so far looks like this:
---
class GPSLog < ActionWebService::API::Base
inflect_names false
api_method :RetrLastPosition,
:expects => [:int],
:returns => [:int]
end

soap_client =
ActionWebService::Client::Soap.new(GPSLog,"http://localhost/WebService/GPSLog/GPSLog.asmx")
ret = soap_client.RetrLastPosition(11);
---

The error I'm getting back from the ASP server is: The request element
&lt;RetrLastPosition xmlns='urn:ActionWebService'&gt; was not
recognized."

....w/ a sc-status error of 500 from IIS.

As I'm new to this it seems there are a zillion things I could be doing
wrong so a working example would be really great or if some can point
me in the right direction it will be greatly appreciated, thanks, mmm

soap_client =
ActionWebService::Client::Soap.new(GPSLog,"http://localhost/WebService/GPSL
og/GPSLog.asmx") ret = soap_client.RetrLastPosition(11);
---

The error I'm getting back from the ASP server is: The request element
&lt;RetrLastPosition xmlns='urn:ActionWebService'&gt; was not
recognized."

Remember, theres a certain company who likes to break every standard in the
book. Please try..

soap_client.default_encodingstyle =
SOAP::EncodingStyle::ASPDotNetHandler::Namespace
