A newbie query about Soap4R and dot net web services

[David Moore]

Can anyone help me with this Soap4r problem?

I have created a simple web service in dot net using Visual studio and
have modified a sample program from the Soap4r distribution to access
it.

Here's the program:

require 'soap/rpc/driver'

class Exchange
ForeignServer = "http://dmoorexp/calcwebservice/service1.asmx"
MyServiceNamespace = 'http://dlogic.com/dmwebservices'

def initialize
@drv = SOAP::RPC::Driver.new(ForeignServer, MyServiceNamespace)
@drv.add_method("Mul", "x", "y")
end

def mul(x, y)
@drv.call(Mul)
return @drv.Mul(x, y)
end
end

e = Exchange.new()
e.mul(10,20)

when run I get the message:

#<SOAP::Mapping::Object:0x2dd5d90>: Server did not recognize the value
of HTTP Header
SOAPAction: . (SOAP::FaultError)

Here is the soap header that the visual studio diagnostic program says
is expected.

POST /calcwebservice/service1.asmx HTTP/1.1
Host: dmoorexp
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://dlogic.com/dmwebservices/Mul"

Any suggestions as to how I can diagnose what is going wrong? I am a
newcomer to Soap and Soap4r. Is there any good tutorial material
covering how to access dot net webservices?

Thanks for anything!

Try this;
@drv.add_method_with_soapaction("Mul", "http://dlogic.com/dmwebservices/Mul", "x", "y")

last week I encountered the same problem.
I modified a sample program in the soap4r distribution.
Hope i helps.

###file: service.rb

require "soap/rpc/driver"
require "RechnerServiceModule"
include RechnerServiceModule

server = 'http://localhost:8080/WSSE_Service/RechnerService.asmx'

wiredump_dev=STDERR

service = SOAP::RPC::Driver.new(server, RechnerServiceModule::InterfaceNS)
service.wiredump_dev=wiredump_dev

service.default_encodingstyle = SOAP::EncodingStyle::ASPDotNetHandler::Namespace
RechnerServiceModule::add_method(service)

result = service.mul(2,2)

print("Result: ", result)


###file:servicemodule.rb
module RechnerServiceModule
InterfaceNS = 'http://schemas.t-systems.com/wse/RechnerService'
Methods=[['mul', 'a','b'],['minus', 'a','b'],['plus', 'a','b'],['hello']]

def RechnerServiceModule.add_method(drv)
Methods.each do |method, *param|
drv.add_method_with_soapaction(method, InterfaceNS+"/#{ method }", *param)
end
end
end

This is far better than my answer. Thanks.
