RoR: Error when connecting affilinet web services (logon function) using savon (ruby on rails) -> Deserialization Failed - ruby-on-rails-3

Question

I try to logon at the affilinet web services via the provided logon function. I'm working in a Rails 3 environment (3.0.x). I utilize the ruby on rails gem Savon in version 2 which in turn uses soap to connect to affilinet.
The most current wsdl can be found here https://api.affili.net/V2.0/Logon.svc?wsdl.
My code looks like this:
client = Savon.client do
wsdl "https://api.affili.net/V2.0/Logon.svc?wsdl"
end
message = {'Username' => 'username', 'Password' => 'password', 'WebServiceType' => 'Publisher'}
response = client.call(:logon, :message => message)
The request generated by Savon:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://affilinet.framework.webservices/Svc" xmlns:ins3="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:ins2="http://affilinet.framework.webservices/types" xmlns:ins1="http://schemas.datacontract.org/2004/07/Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF" xmlns:ins0="http://www.microsoft.com/practices/EnterpriseLibrary/2007/01/wcf/validation" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<tns:WebServiceType>Publisher</tns:WebServiceType>
<tns:Username>username</tns:Username>
</tns:LogonRequestMsg>
</env:Body>
</env:Envelope>
When sending this request to the web service I get this (error) response:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>

Any ideas what's wrong?
EDIT:
The request in soapUI looks like this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:svc="http://affilinet.framework.webservices/Svc" xmlns:typ="http://affilinet.framework.webservices/types">
<soapenv:Header/>
<soapenv:Body>
<svc:LogonRequestMsg>
<!--Optional:-->
<typ:Username>username</typ:Username>
<!--Optional:-->
<typ:Password>password</typ:Password>
<typ:WebServiceType>Publisher</typ:WebServiceType>
<!--Optional:-->
<typ:DeveloperSettings>
<!--Optional:-->
<typ:SandboxPublisherID>?</typ:SandboxPublisherID>
</typ:DeveloperSettings>
<!--Optional:-->
<typ:ApplicationSettings>
<!--Optional:-->
<typ:ApplicationID>?</typ:ApplicationID>
<!--Optional:-->
<typ:DeveloperID>?</typ:DeveloperID>
</typ:ApplicationSettings>
</svc:LogonRequestMsg>
</soapenv:Body>
</soapenv:Envelope>
Maybe the differences in the requests (generated by Savon and by soapUI) are the key!? Especially the different namespaces: svc/typ vs. env/tns. Any ideas? How can I tell Savon to use the svc namespace for the LogonRequestMsg?

Answer 1

Looking into the WSDL of Affili.net it shows that username, password, WebserviceType etc have the wrong namespace.
EDITED for the namespace after another look into your example. Username, Password and WebServiceType are defined in the namespace ins2="http://affilinet.framework.webservices/types" which is tagged by "ins2" in your case.
The quick and dirty way to get over it is
client = Savon.client do
wsdl "https://api.affili.net/V2.0/Logon.svc?wsdl"
end
message = {'ins2:Username' => 'username',
'ins2:Password' => 'password',
'ins2:WebServiceType' => 'Publisher'}
response = client.call(:logon, :message => message)

Answer 2

i think the problem is with namespace order, after several request saw different order in namespace.
This code works for me (savod version 1), overwrite namespaces:
message = {
'ins0:Username' => 'XXXXXXX',
'ins0:Password' => 'XXXXXXX',
'ins0:WebServiceType' => 'XXXXXX',
:order! => ['ins0:Username', 'ins0:Password', 'ins0:WebServiceType']
}
#client.wsdl.document = 'https://api.affili.net/V2.0/Logon.svc?wsdl'
response = #client.request :logon do
soap.body = message
soap.namespaces["xmlns:ins0"] = "http://affilinet.framework.webservices/types"
soap.namespaces["xmlns:ins1"] = "http://schemas.microsoft.com/2003/10/Serialization/Arrays"
soap.namespaces["xmlns:ins2"] = "http://www.microsoft.com/practices/EnterpriseLibrary/2007/01/wcf/validation"
soap.namespaces["xmlns:ins3"] = "http://schemas.datacontract.org/2004/07/Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF"
end
