I am developing a Spring application that will do a basic CRUD operation.The login and after login the population of information is working properly.But when i trying to forward to a page from the main page i.e from where all the information is coming.The URL that is coming is strange and i can not find a reason behind that.i am posting my full code here...

<servlet-mapping>

<url-pattern>/forms/*</url-pattern>

AppController
@Controller
public class AppController {
public static DbImpl dbImpl;
@RequestMapping(value = "/start", method = RequestMethod.GET)
public static ModelAndView getAllinfo() {
ModelAndView mav = new ModelAndView("/mainpage");
System.out.println("mainpage is here");
List<StudentVO> allInfo = dbImpl.populateInfo();
System.out.println("The List is " + allInfo.size());
mav.addObject("mainpage", allInfo);
return mav;
}
@RequestMapping(value = "/doLogin", method = RequestMethod.GET)
public String ShowForm(Map model) {
LoginForm loginForm = new LoginForm();
model.put("loginForm", loginForm);
return "login";
}
@RequestMapping(value = "/doLogin", method = RequestMethod.POST)
public ModelAndView ProcessForm(@Valid LoginForm loginForm,
BindingResult result, Map model) {
String userName = "Jeet";
String passWord = "gamma";
if (result.hasErrors()) {
return new ModelAndView("login", "loginDetails", loginForm);
}
loginForm = (LoginForm) model.get("loginForm");
if (!loginForm.getUsername().equals(userName)
|| !loginForm.getPassword().equals(passWord)) {
return new ModelAndView("login", "loginDetails", loginForm);
}
model.put("loginForm", loginForm);
System.out.println("----->" + loginForm.getUsername());
RedirectView redirectView = new RedirectView("start", true);
return new ModelAndView(redirectView);
}
@RequestMapping(value="/add",method=RequestMethod.GET)
public String aMethod2insert(Map model){
StudentVO studentVO=new StudentVO();
model.put("studentVO", studentVO);
return "insertpage";
}
Now the problem is that when i am doing the login it is working fine and it is generating the URL SpringWebCrudExample/forms/start and coming to this page (the picture i attached here
).Now i have added a link call add in this page from which i will go to a page where i will insert some vlaues, but the problem is here when i click on this URL it is giving SpringWebCrudExample/add this URL.As the result the page is not coming.
