StudentAdmissionController:-

package studentData;

//import java.util.Map;

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RequestParam; 
import org.springframework.web.portlet.ModelAndView;

@Controller 
public class StudentAdmissionController { 
@RequestMapping(value="/AdmissionForm.html", method=RequestMethod.GET) 
public ModelAndView getStudent(){ 
ModelAndView modelandview=new ModelAndView("AdmissionForm");

return modelandview;

}

@RequestMapping(value="/AdmissionSuccess.html", method=RequestMethod.POST) 
public ModelAndView submitStudent(@RequestParam("name") String name,@RequestParam("age") String age){ 
//String name=reqmap.get("name"); 
System.out.println("Name:"+name);//Here I got the name what i entered 
System.out.println("Age:"+age);//Here I got the age what i entered 
//String age=reqmap.get("age"); 
ModelAndView m1=new ModelAndView("AdmissionSuccess"); 
m1.addObject("details",name); 
System.out.println("Empty:"+m1.isEmpty());

return m1;

Can you check with ModelAndViews addAttribute method instead of using addObject?

If addAttribute also is not working, then can you check by giving ${2+2} and see if the EL is working.

Its showing no such method when using addAttribute and i gave ${2+2} the it is coming fine on view as "4"

where it is telling nosuchmethod?Did you notice the change i have made in the method?
Remove the ModelAndView reference, we are now using ModelMap directly and returning the view as String.

Your code is absolutely fine which you have send, the reason why you are not able to get the desired output on browser is because you have imported the portlet package in the controller instead of servlet
