The Google Adwords sample that Nahi included in the samples at
http://dev.ctor.org/soap4r/file/trunk/sample/wsdl/googleAdwords/client.rb
does not work.
In the course of fixing it I ran into a roadblock.
Here's my current fix. I highlight the problems I have fixed, and
areas where I'm not very happy with the fix I found.

require 'soap/wsdlDriver'
require 'soap/header/simplehandler'
#wsdl = 'https://adwords.google.com/api/adwords/v2/CampaignService?WSDL'
wsdl = 'CampaignService.wsdl'
class HeaderHandler < SOAP::Header::SimpleHandler
def initialize(tag, value)
super(XSD::QName.new(nil, tag))
@tag = tag
@value = value
end
#the initial handler from the sample was wrong, it generated 2 level of tags
def on_simple_outbound
@value
end
end

drv.loadproperty('soap/property')

#problem: wiredump_dev does not output anything when running in SSL mode
drv.wiredump_dev = STDOUT
#the file based logger works
drv.wiredump_file_base = "log"
drv.headerhandler << HeaderHandler.new('email', 'patlist@chanezon.com')
drv.headerhandler << HeaderHandler.new('password', 'your_password_here')
drv.headerhandler << HeaderHandler.new('useragent', 'P@ playing with
the API from ruby')
drv.headerhandler << HeaderHandler.new('token', 'your_token_here')
camplist = drv.call("getAllAdWordsCampaigns", GetAllAdWordsCampaigns.new(123))
print camplist

When I run that with a valid adwords developer account, the call is
made and the correct repsonse is sent back, as seen in the filke log.
However the mapper barfs.
I incldue the relevant data.
Any idea of where to look for next is welcome.
I run soap4r soap4r-1_5_4, which seem to have fixed a few things
regarding doc/literal encoding style.

It seems to barf on <getAllAdWordsCampaignsResponse

Here is the rb file generated by wsdl2ruby
[...]
The error happens in soap/mapping/wsdlliteralregistry.rb
# node should be a SOAPElement
def soap2obj(node, obj_class = nil)
print "in soap2obj #{node.inspect}"
unless obj_class.nil?
raise MappingError.new("must not reach here")
end
begin

end
raise MappingError.new("cannot map #{node.type.name} to Ruby object")
end
I guess the problem must lie in the fact that the class
GetAllAdWordsCampaignsResponse is not known to the registry, to be
applied to the response element
{https://adwords.google.com/api/adwords/v2}getAllAdWordsCampaignsResponse>
# {https://adwords.google.com/api/adwords/v2}getAllAdWordsCampaignsResponse
class GetAllAdWordsCampaignsResponse
@@schema_type = "getAllAdWordsCampaignsResponse"
@@schema_ns = "https://adwords.google.com/api/adwords/v2"
@@schema_element = [["getAllAdWordsCampaignsReturn", "Campaign[]"]]
How is this registry informed about the classes that must be used for
mapping when using the wsdl files?
Is there a message to be sent to drv in order to let it know about
default.rb classes?
Thanks in advance for any hints.
