Invoking an External WebService from Rails (WSDL...)

Rails

RoR nuby :

I’m trying to invoke an external WebService from Rails.

I’ve verified the Webservice works (see C# code).

URL : http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=18
WSDL : http://www.webservicex.net/CurrencyConvertor.asmx?wsdl

C# code (works) :

// WebReference declared as WebservicexCurrency

WebservicexCurrency.CurrencyConvertor currencyConverter = new
WebServicesTesting.WebservicexCurrency.CurrencyConvertor();

WebservicexCurrency.Currency currencyUSD =
WebServicesTesting.WebservicexCurrency.Currency.USD;
WebservicexCurrency.Currency currencyJapaneseYen =
WebServicesTesting.WebservicexCurrency.Currency.JPY;

double dRate = currencyConverter.ConversionRate(currencyUSD,
currencyJapaneseYen);

Console.WriteLine("[WebServiceX] USD : Yen => " +
Convert.ToString(dRate));

Rails code?

I just plain toast

Any help would be appreciated, thanks,
Jason
