You are changing the request object, that will indeed do nothing.

What you want is add a variable to the Model. So here's how you can do it:

Instead of:

request.setAttribute("MSG","Thank u"); //This code not doing anything.
return new ModelAndView(new RedirectView("Login.jlc"));

Try this:

Map<String, Object> model = new HashMap<String, Object>();
model.put("MSG", "Thank u");
return new ModelAndView(new RedirectView("Login.jlc"), model); // <-- notice this

This will enable you to access that "Thank u" value through the expression ${model.MSG} and others, if you add them to the model map.
