org.springframework.web.util.NestedServletExceptio n: Request processing failed

Hi all,
I am doing CRUD using spring jdbc template.
insert,select and delete operations are working fine but I got these following exception in update process.

Code:

---

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [java.lang.Integer]: No default constructor found; nested exception is java.lang.NoSuchMethodException: java.lang.Integer.<init>()

---

here is my controller:

Code:

---

@RequestMapping(value="/editCompany/{companyId}", method= RequestMethod.GET)
    public String edit(@PathVariable(value="companyId")Integer companyId,ModelMap map) {
               
                Company company=companyService.get(companyId);
                map.addAttribute("company", company);
                map.put("companyId", companyId);
                return "editCompany";
    }
       
        @RequestMapping(value="/editCompany/{companyId}", method= RequestMethod.POST)
        public String save(@ModelAttribute("company")Integer companyId,Company company,BindingResult result, ModelMap map) {
               
                companyValidator.validate(company, result);
                if (result.hasErrors()) {
                        return "editCompany";
                } else {
                        Integer i=companyService.save(company);
                       
                        return "status";
                }
    }

I have used @Autowired annotation for the controller too.
How to resolve it? any kind of help is appreciated.

You shouldn't use copy/paste to construct your methods... YOur Post method is wrong...

Code:

---

public String save(@ModelAttribute("company")Integer companyId,Company company,BindingResult result, ModelMap map)

---

Remove the highlighted part... Companyid is a path variable not a model attribute, Company is the model attribute (at least if it is stored inbetween request or fully populated upon requests).
