[S2] accessing #application and #request from a Interceptor

[GF]

I have some data stored in #application.mymap
Inside and interceptor I want to put some of this data in
#request.anothermap

How can I access them?
About the #request,  is it right to do this?

        final ActionContext context = invocation.getInvocationContext();
        request = (HttpServletRequest) context.get(HTTP_REQUEST);
        request.setAttribute("anothermap", anotherMap);
