ModelAndView’s model value is not displayed in JSP via EL

Problem

In Spring MVC development, developer try to set a value into a model, and display the value in JSP via EL, e.g ${msg}, but it just outputs the result as it is – ${msg}, not the “value” stored in the model. The EL is just not working in JSP, why?

Spring’s Controller

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class ABCController extends AbstractController{

	@Override
	protected
 
 ModelAndView handleRequestInternal(HttpServletRequest request,
		HttpServletResponse response) throws Exception {

		ModelAndView model = new ModelAndView("HelloWorldPage");
		model.addObject("msg", "hello world");
		
		return model;
	}
	
}
