RequestDispatcher+ menu from database+ SiteMesh problem

Hello.

I'm working with SiteMesh layout system.
I made a decorator which includes other files (check code below). I want to retrive menu items from database, and print them into the decorator file. I have servlet from which I retrive data from db and which should forward this data to the menu.jsp file, but it doesn't do that. When I will type address to my index.jsp file, there are no menu items in my menu bar. This works only when I will enter on my servlet directly (/webapp-dir/MenuServlet), and here everything displays great - I have a <h1> and the menu items under it (just like in the menu.jsp file below), but the address in the address bar is not webapp/template/menu.jsp, the address is /webapp/MenuServlet. I don't how to describe it exactly, but the final effect is that, that I don't get the menu items in my pages which use the decorator. I don't want to include the servlet, I want to include menu.jsp.

btw. I have second question. I want to build my website based on the MVC. Is this correct? Model = hibernate mapping classes, Controller (place where i connect to the database and forward the data to the jsp) = servlet, view = jsp page. Or should it be Model = Java class which connects to the db and saves the data to (for example) the List, Controller = servlet where I get the List variable from Model class and forward it to the JSP page, view = jsp page ?

decorator:

Servlet in which I retrive menu items and their's addresses from database (I use Hibernate):

package servlets;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import mapsFiles.Menu;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

/**
 * Servlet implementation class MenuDB
 */
@WebServlet("/MenuDB")
public class MenuDB extends HttpServlet {
	private static final long serialVersionUID = 1L;

/**
	 * @see HttpServlet#HttpServlet()
	 */
	public MenuDB() {
		super();

}

/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		doPost(request, response);
	}

/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("text/html");  
        PrintWriter out = response.getWriter(); 
		String menuName = request.getParameter("menuName");
		String linkToMenu = request.getParameter("linkToMenu");
		Session session = null;
		SessionFactory sessionFactory = new Configuration().configure()
				.buildSessionFactory();
		session = sessionFactory.openSession();
		Transaction transaction = session.beginTransaction();

Query query = session.createQuery("from Menu");
		List<Menu> menuList;
		menuList = query.list();
		transaction.commit();
		session.flush();
		System.out.println("Database contents delivered...");
		session.close();

request.setAttribute("menu", menuList);
		RequestDispatcher view = getServletContext().getRequestDispatcher("/template/menu.jsp");  
        view.forward(request,response);  
	}

}

and the menu.jsp:
