How can I print incoming and outgoing SOAP messages on my Web services client?
The message handler chain can be modified to add code that dumps the contents of the SOAP message and response. 
  
  | factory pluggableHandler |
  factory := ( SstWSContainer containerNamed: 'VastSampleClientContainer' ) handlerFactory.
  pluggableHandler :=SstWSPluggableHandler new
    invokeBlock: [ :anSstWSMessageContext |  | message |
       [ 
      message :=  anSstWSMessageContext propertyNamed: ##wsTransportMessageRequest.
      AbtXmlUtility logError: 'Request->'.
      AbtXmlUtility logError: message  asString.
      AbtXmlUtility logError: ''.
      AbtXmlUtility logError: 'Response->'.
  
      " NOTE:  The output message is not stored in the message context. "
      message :=  anSstWSMessageContext propertyNamed: ##wsTransportMessageResponse.
      AbtXmlUtility logError: message header debugPrintString.
      btXmlUtility logError: message contents asString  ] fork
      ].
  
  factory
    register: pluggableHandler
    named: 'wsHttpClientResponseHandler' inNamespace: factory globalNamespace
 
To disable the tracing code, execute the snippet below: 
  
   | factory |
   factory := ( SstWSContainer containerNamed: 'VastSampleClientContainer' ) handlerFactory.
   factory
      register: SstWSNoOperationHandler default
      named: 'wsHttpClientResponseHandler'  inNamespace: factory globalNamespace
