Hi all,  
I must access a webservices that expect the SOAP action as a soap  
header. I want to add this soap header automatically but I dont know  
where to hook in.  
My actual solution is to create a header and remove it after consuming.  
The code looks like this:

require ‘SystemDriver.rb’  
require ‘soap/header/simplehandler’

# define the action soap header

class ActionHandler \< SOAP::Header::SimpleHandler  
HeaderName =  
XSD::QName.new(‘[http://schemas.xmlsoap.org/ws/2004/08/addressing/','Action](http://schemas.xmlsoap.org/ws/2004/08/addressing/','Action)’)  
@m\_action

def initialize(action)  
super(HeaderName)  
@m\_action = action  
end

def on\_simple\_outbound  
@m\_action  
end  
end

# create the connection / interface

endpoint\_url = “[http://localhost:1500](http://localhost:1500)”  
obj = Public.new( endpoint\_url )

# enable debug output

obj.wiredump\_dev = STDERR if $DEBUG

ns = ‘[http://mynamespace.com/my/path](http://mynamespace.com/my/path)’

# getIdentity

# create action soap header

actionHandler = ActionHandler.new( ns + ‘/getIdentity’ )

# add action soap header

obj.headerhandler.add( actionHandler )

# do the request

emptyRequest = nil  
puts 'getIdentity: ’ + obj.getIdentity(emptyRequest).identityString  
puts ‘’

# remove action soap header for reusing the connection / interface

obj.headerhandler.delete( actionHandler )
