Нет ответа при вызове веб-службы в рубине через процесс BPEL

Я использовал стимулятор Wash out для создания некоторых веб-сервисов на ruby. Все идет нормально. С savon gem получить ответ не проблема. Но я создаю процесс BPEL и хочу вызвать веб-службу (это просто BPEL)! Запрос не проблема, так что знайте, что я нахожусь в ruby ​​soap_service и не знаю, как ответить на процесс BPEL!?

    soap_action "concat",
    :args   => { :concatRequest => { :a => :string, :b => :string } },
    :return => { :concatResponse => { :result => :string } }

  def concat
    # something I want to do in ruby
    puts "*******************************************************************"
    puts "************************   CONCAT   *******************************"
    puts "*******************************************************************"
    result = params[:concatRequest][:a] + params[:concatRequest][:b]
    puts "RESULT: " + result
    puts "*******************************************************************"
    # and then send response to BPEL process
    puts render :soap => ( { :concatResponse => {:result => result} } )
  end

Процесс BPEL все еще ожидает ответа и не получил его! Я надеюсь, что кто-нибудь может мне помочь :-) ...

и вот мой файл WSDL:

Вот ОШИБКА, которую я получаю, когда процесс BPEL вызывает веб-службу:

ERROR [INVOKE] Failure during invoke: Unable to process response: SOAP body does not contain expected part wrapper: service {urn:WashOut}service port contextserver_port wrapper {urn:WashOut}concatResponse
INFO  [BpelRuntimeContextImpl] ActivityRecovery: Registering activity 13, failure reason: Unable to process response: SOAP body does not contain expected part wrapper: service {urn:WashOut}service port contextserver_port wrapper {urn:WashOut}concatResponse on channel 24

Это мое действие вызова в моем процессе BPEL:

<bpel:invoke name="Invoke" partnerLink="contextserver" operation="concat" portType="ns1:contextserver_port" inputVariable="concatRequest" outputVariable="concatResponse"></bpel:invoke>

concatRequest => Сообщение "concat" concatResponse => Сообщение "concat_response"
