Can't receive any page 404 HTTP error

Question

I have an issue after I install postman. I try to work with REST service but firstly I want to check how it works on normal browser. So I tried on latest pages with normal view like that one below:

@Controller
public class HomeController {

@RequestMapping("/")
public String welcome(Model model)
{
    model.addAttribute("greeting", "Witaj w sklepie internetowym");
    model.addAttribute("tagline", "Wyjątkowym i jedynym sklepie");

    return "welcome";
}
@RequestMapping ("/welcome/greeting")
public String greeting() {
        return "welcome";
    }
}

It works fine I get back the .jsp page. Later I want to get the REST page in postman:

@Controller
@RequestMapping(value = "rest/cart")
public class CartRestController {

    @Autowired
    private ICartService cartService;
    @Autowired
    private IProductService productService;

    @RequestMapping(method = RequestMethod.POST)
    public @ResponseBody Cart create(@RequestBody Cart cart) {
        return cartService.create(cart);
    }

But then i receive HTTP 404 - not found status, and even if I want to get my "normal" pages with view i get always HTTP 404 status. In console log I getting also this error below but the server starts. So i dont know I have that one before. I tried to remedy with it like someone said on this answer https://stackoverflow.com/a/8128255/7491837 but it dont help me.

SEVERE: Error configuring application listener of class [org.springframework.web.context.ContextLoaderListener]
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

And also i tried to turn off my code with REST services but it dosen't help me. Any ideas what can be wrong? I'm stuck..

Not sure which server you are using. Hope the below helps :

below are the things that you can try out :

• Add all the necessary jar files in "Deployment Assembly".
• Please do a clean build of your project and re-check.
• Remove the deployed file from your server.
• Also clean the server (Tomcat/Websphere) Work Directory (Right click on Tomcat server and then do Clean Tomcat Work Directory).
• If this doesn't work then delete your server and re-install it properly and then check.

If the above doesn't work then do :

• Create a new workspace.
• Add server.
• Add your project.
• Add all necessary jar files in Deployment Assembly.
• Clean Build.
• Deploy in server and check.
