Strange error with validation - Invalid property

[sam White]

Hi, witih spring mvc 3.0.4, and jsp, I created a custom validator for validating password and confirmPassword. But when I click the submit button, it thrown the following exception:

Sorry for the lengthy codes I just don't know how to shorten it in order to show the most relevant codes here.
Any suggestion is very appreciated.
Thanks

Hello, I changed the submit method a little bit, which is shown as below:

if (result.hasErrors()) {
                    AdminSignupBean admin = products.get(pbid);
                    req.getSession().setAttribute("pbid", pbid);
                    BeanUtils.copyProperties(adminsignup, admin, new String[] {"pbid", "mpf", "password", "confirmPassword"});
                    map.addAttribute("adminsignupbean",admin);
                    ...
                    return "adminsignup/createadmin";
                }
                Set<ConstraintViolation<AdminSignupBean>> violations 
                        = validatorFactory.getValidator().validate(adminsignup);
                for(ConstraintViolation<AdminSignupBean> violation : violations) {
                    logger.debug("=========Violation Message:- " + violation.getMessage());
                    AdminSignupBean admin = products.get(pbid);
                    req.getSession().setAttribute("pbid", pbid);
                    BeanUtils.copyProperties(adminsignup, admin, new String[] {"pbid", "mpf", "password", "confirmPassword"});
                    ....
                    return "adminsignup/createadmin";
                }

The error now changed to:

I am still confused about "password.confirmPassword" bean , as I don't have this bean written in my project.

Any suggestion is very appreciated.
