code: public void initialize( ActionMapping mapping, FlowController flowController )
      {
          _mapping = mapping;
          _mappingPath = mapping != null ? mapping.getPath() : null;
          _flowController = flowController;
          _servletContext = flowController.getServletContext();
      }
docs: Set the current ActionMapping and associated FlowController.  Normally, this method is called
  by the framework, but you can use it to initialize the Forward object in order to call {@link #getPath}.
  
  @deprecated Use {@link #initialize(ActionMapping, FlowController, ServletRequest)} instead.
  @param mapping the current ActionMapping; this can be obtained from {@link FlowController#getMapping}.
  @param flowController the object in which to look for referenced return-form members.
