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

[smya.dsh]

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.

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:

@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.
