         MovieFinderUser existingUser = finderUserImp.findByEmail(email);
         
         if(existingUser!=null && existingUser.getPassword().equals(movieFinderLoginUserPojo.getPassword())){
             httpSession.setAttribute("isLoggedIn", true); 
             System.out.println("The Email and Password is Correct ");
             return "redirect:/home"; // Redirecting to the home page
            }

             return "login";
             }
        }

@GetMapping("/login")
    public String loginPage(Model model) {
        model.addAttribute("movieFinderLoginUserPojo", new MovieFinderLoginUserPojo());
        return "login";
    }
    
    
    @PostMapping("/loggedIn")
    public String loggedInUser( @Valid @ModelAttribute("MovieFinderLoginUserPojo") MovieFinderLoginUserPojo movieFinderLoginUserPojo , BindingResult bindingResult  ,  HttpSession httpSession , Model model) {
        
        if(bindingResult.hasErrors()) 
        {
            System.out.println(bindingResult.getErrorCount());
            return "login";
        }
        
        try {
        String email = movieFinderLoginUserPojo.getEmail();
        
         MovieFinderUser existingUser = finderUserImp.findByEmail(email);
         
         if(existingUser!=null && existingUser.getPassword().equals(movieFinderLoginUserPojo.getPassword())){
             httpSession.setAttribute("isLoggedIn", true); 
             System.out.println("The Email and Password is Correct ");
             return "redirect:/home"; // Redirecting to the home page
            }
        
         else {
             model.addAttribute("error", "Invalid email or password.");
             return "login";
             }
        }
        catch (EmptyResultDataAccessException e ) {
            e.getMessage();
             return "login";
        }
        }
