How can i use my Controller in spring mvc?

I have a problem with my Controller class: I create my project with maven and I add the dependencies for hibernate and Spring. When I start the app I can go in the first page from the servlet, but when I call any method I get 404. I try many solutions, but no one work, I use a web logic server, there is some particular configuration for this server? In the project this is my actual situation:

AppController.java

@Controller
@RequestMapping("/")
public class AppController {


        @RequestMapping(value = "/two", method = RequestMethod.GET)
        public String two() {
            System.out.println("work?");
            return "newFile";
        }

}

i try also with ModelAndView

registration.jsp

<!DOCTYPE HTML>
<html>
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
      <title>Title</title>
      <style type="text/css">
         form {
         display: inline-block;
         }
      </style>
   </head>
   <body>
      <form action="/two" method="GET">
         <p class="message">//Not registered? 
            <input type="submit" value="Create an account">
         </p>
      </form>
   </body>
</html>

I resolve my problem, the process "oracle xe tns listener" use my port 8080, i suppose the server block the call on controller. I found this solution because i try to start my application on tomcat and i had the port busy, so I termitate the process and my application go on tomcat and web logic server :)

If I understand the problem correctly, you having new controller component and request mapping which should be invoked on form submission.

I see the below issues in xml configuration

you are not using spring DispatcherServlet in web.xml. This class is responsible for processing and handles the request and forwards to appropriate controller

You are defining the mapping in web.xml with class com.reply.servlet.LDSServlet. how would the LDSServlet class look like?

Basically DispatcherServlet, will process the configuration (Controller classes and request mappings) and uses this for picking the appropriate controller while request arrives.

EDIT:

you should be including the context-path in the form action.

try this way, it is work fine with me.

@Controller
public class HelloController {

    @RequestMapping(value = { "/", "/welcome**" }, method = RequestMethod.GET)
    public ModelAndView welcomePage() {

        ModelAndView model = new ModelAndView();
        model.addObject("title", "Spring Security Hello World");
        model.addObject("message", "This is welcome page!");
        model.setViewName("hello");
        return model;

    }
