AdminInfoControl.java

@Controller
public class AdminInfoControl {

        private AdminInfoService service;

    @RequestMapping(value = "/emp_change", method = RequestMethod.POST)
    public String doActions(@ModelAttribute JtAdminInfo emp, BindingResult result, @RequestParam String action, Map<String, Object> map) {
        service = new AdminInfoService();
        JtAdminInfo empResult = new JtAdminInfo();
        switch (action.toLowerCase()) {

            case "login":
                JtAdminInfo search = service.getFindAdmin(emp.getEmailId());

                empResult = search != null ? search : new JtAdminInfo();
                break;
        }
        map.put("index", empResult);
        map.put("empList", service.getAll());
        return "index";
    }
}

I'm getting following error :

Neither BindingResult nor plain target object for bean name 'emp_change' available as request attribute

Anyone please help me to correct this. Please let me know, if information is not sufficient.

I have added following method in my controller and works fine.

    @RequestMapping("/index")
    public String setupForm(Map<String, Object> map) {
        map.put("index", new JtAdminInfo());
        return "index";
    }

Just answered on almost the same question.. You are obtaining emp_change as a model attribute in doActions method but you didn't set it as a model attribute previously. So, set your emp_change as a model attribute in some method that e.g. shows your index.jsp page. Something like this:

@RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView showIndex() {
    ModelAndView mav = new ModelAndView("index");
    mav.addObject("emp_change", new JtAdminInfo ());
    return mav;
}
