Hi,

    In my controller object, it creates a ModelAndView object and invoke the following methods:

ModelAndView mv = new ModelAndView("hello");
mv.addObject(req);
mv.addObject(resp);
mv.addObject(ctx);


I would like to know how to access these objects (i.e. req, resp, ctx) in my JSP??
Thanks.

You should use the ModelAndView#addObject(String, Object) [1] method instead.

mv.addObject("req", req);
mv.addObject("resp", resp);
mv.addObject("ctx", ctx);

They are put in the ServletRequest as attributes.  Use the ServletRequest#getAttribute(String) method [1] to access them:

request.getAttribute("req")
request.getAttribute("resp")
request.getAttribute("ctx")
