Simple Savon SOAP request not working - ruby

Question

I have the following WSDL, generated from soapUI. When I test the
request from soapUI, it works fine but throws exception from savon.
I am using savon 0.9.2 on Linux.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/
envelope/" xmlns:mes="http://www.domain.com/sub/05/00/Messages">
<soapenv:Header/>
<soapenv:Body>
<mes:loginRequest>
<!--Optional:-->
<mes:Username>admin</mes:Username>
<!--Optional:-->
<mes:Password>pass</mes:Password>
<!--Optional:-->
<mes:ImpersonationUsername></mes:ImpersonationUsername>
<!--Optional:-->
<mes:ApplicationName></mes:ApplicationName>
</mes:loginRequest>
</soapenv:Body>
</soapenv:Envelope>
The script, which causes Errors:
require 'rubygems'
require 'savon'
require 'pp'
client = Savon::Client.new "http://domain/Service.asmx?WSDL"
response = client.request(:mes, "login") do
soap.body = {
"mes:Username" => "test",
"mes:Password" => "test",
"mes:ImpersonationUsername"=>"Test",
"mes:ApplicationName"=>"test"
}
end
pp response.to_hash
The Output:

The output from SoapUI is the following:

</LoginResult>
</soap:Body>
</soap:Envelope>

Answer 1

You might want to set the namespace in your savon request: client.namespaces["xmlns:mes"] = "http://www.domain.com/sub/05/00/Messages"

Answer 2

the request you send creates the following soap message
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mes="urn:namespace.com"
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Body>
<mes:login>
<mes:Username>test</mes:Username>
<mes:Password>test</mes:Password>
<mes:ImpersonationUsername>Test</mes:ImpersonationUsername>
<mes:ApplicationName>test</mes:ApplicationName>
</mes:login>
</env:Body>
I guess that's not what your intention is?
please insert the following lines into your code after the .new
Savon.configure do |c|
c.log = true
end
that shows the outgoing message.
