Error status 404: origin server did not find a current representation

I have a netbeans Project with the structure below. When i access localhost:8080/Project/Song it appears the error:

HTTP status 404

Description: The origin server did not find a current representation for the target resource.

Do you know how where is the issue and how to correct it?

Project structure:

 Project
        Web Pages
            META-INF
            WEB-INF
               web.xml
               lib
                  jstl-1.2.jar 
           songs.jsp

        Source Packages
            data
                Song.java

@WebServlet(name = "/Song")
public class Song extends HttpServlet {
    /*protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    }*/

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        QueryManager qm = new QueryManager();
        ArrayList<ArrayList<String>> result = qm.getSongs();
        qm.closeConnections();

        request.setAttribute("result", result.get(0));
        request.setAttribute("id", result.get(1));
        RequestDispatcher view=request.getRequestDispatcher("songs.jsp");
        view.forward(request,response);
    }

    public void init(){
        System.out.println("Songs page");
    }
}

You are using both servlet mapping methods. Use one of them. Annotation method or web.xml Remove servlet mapping from web.xml file. Means remove below portion

<servlet>
    <servlet-name>Song</servlet-name>
    <servlet-class>Song</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>Song</servlet-name>
    <url-pattern>/Song</url-pattern>
  </servlet-mapping>

The below line is not valid. You need to give the fully qualified name of your class. anyway you dont need this if you have annotation

<servlet-class>Song</servlet-class>

use this.

  @WebServlet(name = "Song", urlPatterns = {"/Song"})
