RequestMaping calling two times for one submit

[sunflower_rahul]

Ciao Tutti,

I have one problem in the Spring MVC . As i am new to it.

I am using the annotation in the controller

@Controller
public class WelcomeAnnotatedController {

    Log log = LogFactory.getLog(this.getClass());

    @Autowired
    private SecondBean secondBean;
    //it will call the method, when the submitting the form
    @RequestMapping(value="/actionName.htm",method = RequestMethod.POST)
    public ModelAndView onSubmit() {
        System.out.println("<<<<<<<<<<<<<onSubmit POST WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>");
        String message = secondBean.getFirstBean().foo();
        System.out.println("<<<<<<<<<<<<<Message>>>>>>>>>>>>>>>>>>>>>>>" + message );
        ModelAndView mav = new ModelAndView("myview").addObject("message",message);
        return mav;
    }

    @ModelAttribute("userList")
    public List<String> populateUserList() {
        ArrayList<String> list = new ArrayList<String>();
        list.add("Rahul");
        list.add("Joy");
        list.add("Anand");
        return list;
    }

    @RequestMapping(method = RequestMethod.GET)
    public String showForm(ModelMap map) {
        map.addAttribute("message", "Hello,This is My First Jsp");
        System.out.println("<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>>>>>");
        User user = new User();
        map.addAttribute("user", user);
        return "myview";
    }

    @RequestMapping(value="/backUser.htm",method = RequestMethod.POST)
    public String backToWelcome() {
        System.out.println("going back to welocme page");
        return "welcome";
    } 

Whenever i am calling the RequestMapping method, its calling two times, here when i am trying to addUser, its tried to insert two times(Sometime).

I am not able to figure out what is the problem. Whenever i am calling the same RequestMapping continously 3-4 times,suppose in this case @RequestMapping(value="/backUser.htm",method = RequestMethod.POST), then it will call two times.
output of the RequestMapping as

<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
<<<<<<<<<<<<<<<<<<<<<<<<<showUserForm GET WelcomeAnnotatedController>>>>>>>>>>>>>>>>>>>>>>>> >>>
going back to welocme page
going back to welocme page

Please help me , because , i am going to use SPRING MVC first time.

Thanks
Rahul
