Hi,

I'm trying to write a little SOAP WSDL client to get a currency
conversion rate. I have tried what is listed below but I get the error
below. I don't know what I'm doing but I've been trying to follow the
pickaxe book on page 252. Any suggestions to get this working?

Thanks,
Peter

## RUBY SCRIPT

require 'soap/wsdlDriver'
require 'cgi'

WSDL_URL = "http://www.webservicex.net/CurrencyConvertor.asmx?...

soap = SOAP::WSDLDriverFactory.new(WSDL_URL).createDriver

result = soap.ConversionRate("USD", "CAD")

puts result

## ERROR

Here is the example. The service is doc literal
and for those services pass the arguments as a
hash.

------------------------------

require 'soap/wsdlDriver'

WSDL_URL = "http://www.webservicex.net/CurrencyConvertor.asmx?...

soap = SOAP::WSDLDriverFactory.new(WSDL_URL).create_rpc_driver
# soap.wiredump_dev = STDOUT
result = soap.ConversionRate(:FromCurrency => "USD", :ToCurrency =>
"CAD")

puts result.conversionRateResult
--------------------------------

The messages :
ignored element: {http://schemas.xmlsoap.org/...}binding
ignored element: {http://schemas.xmlsoap.org/...}operation
ignored element: {http://schemas.xmlsoap.org/...}urlEncoded
ignored element: {http://schemas.xmlsoap.org/...}mimeXml
ignored element: {http://schemas.xmlsoap.org/...}content
ignored element: {http://schemas.xmlsoap.org/...}address

are for unsupported bindings in soap4r. .NET services often include
bindings for as urlEncoded, http GET and http POST in addition to
SOAP.

cheers,
emil

Hi Emil,

Thanks for the respone. I've tried what you posted and it didn't work.
Did you test this? I got the following error

Unknown element {http://schemas.xmlsoap.org/...}binding.
Unknown element {http://schemas.xmlsoap.org/...}operation.
Unknown element {http://schemas.xmlsoap.org/...}urlEncoded.
Unknown element {http://schemas.xmlsoap.org/...}mimeXml.
Unknown element {http://schemas.xmlsoap.org/...}binding.
Unknown element {http://schemas.xmlsoap.org/...}operation.
Unknown element {http://schemas.xmlsoap.org/...}content.
Unknown element {http://schemas.xmlsoap.org/...}mimeXml.
Unknown element {http://schemas.xmlsoap.org/...}address.
Unknown element {http://schemas.xmlsoap.org/...}address.
conversionWS2.rb:5: undefined method `create_rpc_driver' for
#<SOAP::WSDLDriverFactory:> (NoMethodError)

I have also tried another suggestion that almost works. It always
returns a conversion rate of zero. But it is nice because it doesn't
use WSDL.

require 'soap/rpc/driver'

service =
SOAP::RPC::Driver.new("http://www.webservicex.net/CurrencyConvertor.asmx","http://www.webserviceX....)
service.default_encodingstyle =
SOAP::EncodingStyle::ASPDotNetHandler::Namespace
service.add_method_with_soapaction("ConversionRate",
"http://www.webserviceX.NET/Conversion..., "FromCurrency",
"ToCurrency")
service.wiredump_dev = STDERR
puts service.ConversionRate("USD","CAD")

Any other ideas?

Thanks,
Peter

Resolved.

I upgraded to Ruby 1.8.4 and now my example code works.
