code: public static ActionResult lookup( String actionName, ServletContext context, HttpServletRequest request,
                                         HttpServletResponse response )
          throws Exception
      {
          return PageFlowUtils.strutsLookup( context, request, response, actionName, null );
      }
docs: Resolve the given action name to a URI.  This version assumes that the ActionServlet
  class should be {@link PageFlowActionServlet}.
  Note: this method invokes the full action-processing cycle on a {@link ScopedRequest}.  Use
  {@link FlowController#resolveAction} to resolve the URI for an action in the current page flow.
  @deprecated Use {@link PageFlowUtils#strutsLookup} instead.  This method will be removed in v1.1.
