Using .Net SOAP service

Ruby
1

Hi,

I am getting this error while trying to access .NET based SOAP Web
service

#SOAP::Mapping::Object:0xb7c86218:
System.Web.Services.Protocols.SoapException: Server was unable to
process request. —> System.NullReferenceException: Object reference
not set to an instance of an object. (SOAP::FaultError)

My code to access this service is:

require ‘soap/wsdlDriver’
wsdl = 'HugeDomains.com
driver = SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
puts driver.GetVals(‘136’)

I have tried many things but still i am not able to get this code
working. Please tell what should i do to get this working

Try putting the ‘136’ in a SOAP::SOAPString or SOAP::SOAPInt:

p driver.GetVals(SOAP::SOAPString.new(“136”))
or
p driver.GetVals(SOAP::SOAPInt.new(136))

If that doesn’t work, i try using the wsdl2ruby generator to create
the class stubs. It will create a class for each parameter. In your
case, it will be something like:

p driver.GetVals( GetVals.new(SOAPString.new(“136”)))

Thanks Ben,

I finally figured out the problem i had to pass arguments as hash like
this:

puts driver.GetVals(:parameter => “136”)

FYI: Generating stub files with wsdl2ruby.rb against a WSDL could help
to understand what arguments you should pass.

% wsdl2ruby.rb --wsdl Foo.wsdl --type client --force
