Can't get Savon to form the right XML

I've used SOAP before but many, many years ago and try to stay clear if I can help it.

Short story...

• Using "Soap Client" OS X app I can get the response I wish.
• If I use client.request :foo_web_serivce, :language_count, :body => { :foo_app_id => "...", :session_id => "..." } then I get a Status 200 but my results are -1 as I believe the app_id is not recognised.
• If I try to replicate the Soap Client call (<LanguageCount>) rather than Savon's call (<foo_web_service:LanguageCount>) then I get an Status 500.

Please advise and thanks in advance.

Long Story...

Using SOAP Client I can see that the correct request XML is:

User-Agent: Mac OS X; WebServicesCore (357)
Content-Type: text/xml
Host: redacted
Soapaction: http://tempuri.org/redacted/LanguageCount

<?xml v开发者_高级运维ersion="1.0" encoding="utf-8"?>
  <SOAP-ENV:Envelope
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
    SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

          <fooAppID xsi:type="xsd:string">12345678-1234-1234-1234-123456789123</fooAppID>
          <sessionID xsi:type="xsd:string">12345678-1234-1234-1234-123456789123</sessionID>
        </LanguageCount>
      </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>

However, when I try to do it in the console like so:

ruby-1.8.7-p302 > client = Savon::Client.new do |wsdl, http, wsse|
ruby-1.8.7-p302 >       wsdl.document = "http://FooService.cloudapp.net/FooService.svc?wsdl"

But when I use the namespace of foo_web_service, I get:

Long story short, I had to make 3 changes.

1. Changed response = client.request :language_count to response = client.request "LanguageCount"
2. Added :xmlns => "http://tempuri.org/" to the end of the client.request call
3. Explicitly called the SOAPaction like: client.http.headers["SOAPAction"] = '"http://tempuri.org/FooService/LanguageCount"'

Hope this helps someone as I've been in SOAP hell for the weekend and hopefully I'll stop someone else being there.
