Hello,

Thank you,

I've updated to 1.5.6 RC2 and it works now, here is my code:

/* Start code */

require 'soap/header/handler'
require 'http-access2'
require 'soap/wsdlDriver'

wsdl = "myWsdl.wsdl"

factory = SOAP::WSDLDriverFactory.new(wsdl)
driver = factory.create_rpc_driver

# save the SOAP message
driver.wiredump_file_base = File.join(File.dirname (__FILE__), "tmp")
driver.wiredump_dev = STDERR if $DEBUG

class EmptyHeaderHandler < SOAP::Header::Handler

  def on_outbound(header)
    # dump SOAPHeader even if it has no item
    header.force_encode = true
    header.extraattr['xmlns'] = 'urn:foo'
    # no item needed
    nil
  end

end

driver.headerhandler << EmptyHeaderHandler.new(XSD::QName::EMPTY)

parameters = { #... my parameters }

req = driver.Air_MultiAvailability(parameters)

/* End of code */


Well, I have an other question I'll ask in a new topic about wsdl2ruby.
