Recently I had to consume a .NET web service that uses WSSE based authentication. Thanks to the intarweb, I was able to get started with soap4r and insert WSSE authentication headers into my SOAP requests.The samples available on the tracker are also quite comprehensive, other than being light on explanation.
I did encounter an error when using the automatically generated client application:
./defaultMappingRegistry.rb:5: uninitialized constant SOAP::Mapping::EncodedRegistry (NameError) from ./defaultDriver.rb:2:in `require'
from ./WSDLService_PortClient.rb:2:in `require'
It appears that the soap library provided with Ruby 1.8.6 is being used instead of the soap4r gem. The version bundled with Ruby doesn’t have some classes referenced by the generated stubs (from wsdl2ruby) as well as a bunch of other functionality.
The solution is simple (after knowing what’s wrong of course): explicitly reference the gem so that Ruby knows which one to use.
Just insert this snippet before the code that references the missing classes and you’re good to go.
