Example of a basic SOAP service written in Ruby (1.9), the code contains explanatory comments.
The EchoService works with Ruby 1.9.2 and 1.9.3. It will not work with JRuby because of Nokogiri issue #494
On 22-08-2020 I updated the gems and found that this service still works with Ruby 2.6.6
If you have any issues, suggestions, improvements, etc. then please log them using GitHub issues.
To run the EchoService run "bundle exec rackup"
The default endpoint URL in the WSDL is http://localhost:9292/echo_service, you can set the environmental variable BASE_URL to replace http://localhost:9292 with whatever is appropriate for you (per example http://echo.without-brains.net)
