Document style Webservice

Hello
   
  I am able to invoke JAX/RPC service thru WSIF, but unable to do for doc/literal webservice thru WSI. I am using ApacheAXIS provider and setting flag "CONTEXT_OPERATION_STYLE_WRAPPED" in operataion context
   
  assigning data in format - 
    String inXml = msgTransformer.ObjectToXML(pDto);
  WSIFMessage msg = pWsifOperation.createInputMessage(inXml);
   
  the question i have is - 
  If i am invoking doc/literal service, do i need to provide serialization/deserilization code ?
  If yes, Where and How i need to provide it ? 
  Please provide example.
   
  Thanks
