WARN PageNotFound:1120 - No mapping found for HTTP request with URI

I got a problem when developing spring project. I am getting warnings after returning from the controller. This is the configuration

<?xml version="1.0" encoding="UTF-8"?>

</servlet-mapping>

From the index.jsp I am calling this controller

@Controller
@RequestMapping("/polavaram")
public class LoginController implements ServletContextAware {
private ServletContext servletContext;

@Override
public void setServletContext(ServletContext servletCtx) {
    this.servletContext = servletCtx;

}

@RequestMapping(value = "/login", method = RequestMethod.GET)
public ModelAndView login() {
    return new ModelAndView("loginpage");

}

This is my tiles configuration

<definition name="loginpage" extends="baseLayout">
    <put-attribute name="title" value="Login Page" />
    <put-attribute name="body" value="/jsp/loginpage.jsp" />
</definition>

This is the warning I am getting 00:16:04,849 WARN PageNotFound:1120 - No mapping found for HTTP request with URI [/PolavaramWebApp/polavaram/js/bootstrap.js] in DispatcherServlet with name 'polavaram'

I have this folder structure

webapp
   css
   jsp
   js
   img

There are some libraries in them. I am not able to access them in the loginpage.jsp
