How do I generate a WSDL using Ruby? - ruby

Question

I starting to work with Ruby and Soap and had some questions:
How do I generate a WSDL file for the service I created?
Will it be compatible with an .NET client ?
begin
class MyServer < SOAP::RPC::StandaloneServer
# Handler methods
def add(a, b)
return a + b
end
def div(a, b)
return a / b
end
# Expose our services
def initialize(*args)
add_method(self, 'add', 'a', 'b')
add_method(self, 'div', 'a', 'b')
end
end
server = MyServer.new("MyServer",
'urn:ruby:calculation', 'localhost', 8080)
trap('INT'){
server.shutdown
}
server.start
rescue => err
puts err.message
end

ActionWebService (previously in Rails core, now a gem) has tools to generate WSDL files. You can use the tools even if you're not running your service within Rails.

As for whether it will work with a .NET client, the answer is maybe. Many .NET clients seem to expect Microsoft's "extended" SOAP info, which .NET webservices provide by default. If the client is also able to consume a service without that extra stuff, then sure.
UPDATE #1
The above link no longer appears to work. There are however forks of ActionWebService that have popped up over on github. You can see a pretty good list of them here. Here are a couple of links to some key versions:
original datanoise version
clevertechru's port, works w/ Rails 3.1.* & Ruby 1.9
