How to deploy and run first JSP application on Tomcat server 8.0.2?

Question

I hope a tomcat veteran can help me here! I have two major problems (linking the pages and database connectivity)

A. Linking the pages:

I renamed myapps.war to ROOT.war;
I have deployed the WAR file in tomcat/web-apps/application.com/ROOT Tomcat then unpacked the WAR and generated a sub file;
I have placed jstl.jar in tomcat/web-apps/application.com/ROOT/WEB-INF/lib.

The index.jsp displays well in the browser. Everything appears fine but when I click on any given URL whether is /viewCart to see cart.jsp or category?{category.id} to display data from that selected category, I receive a 404 Http error resource not available in the browser. All the pages (except the index page) are stored in tomcat/web-apps/application.com/ROOT/WEB-INF/view.

Since no other page but index.jsp displays at all, I'm guessing I have to move the files up and put them in the same sub-directory of index.jsp? But does it not remove all the purposes of WEB-INF to hide dynamic pages?

I'm a bit confused. I dont know what i'm doing wrong...

B. Database connectivity

I have downloaded the platform independant JDBC driver here and placed it (mysql-connector-java-version-bin.jar) in tomcat/web-apps/application.com/ROOT/WEB-INF/lib

I'm trying to follow this documentation: http://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-tomcat.html

This is where it gets a bit confusing... In the documentation they say to configure the JNDI DataSource by adding a declaration resource to $CATALINA_HOME/conf/server.xml in the context that defines the web application and they provide a piece of code. My question for this segment is: what do they mean by server.xml? Do they mean web.xml or persistence.xml? Because the JNDI name of the data source used by my application to interact with the database is found in the persistence unit (persistence.xml file) and is stored in tomcat/web-apps/application.com/ROOT/WEB-INF/classes/META-INF... Should I move persistence.xml elsewhere or should I just add piece of code in web.xml?

Controller entry for /cart:

// if cart page is requested
        } else if (userPath.equals("/viewCart")) {

            String clear = request.getParameter("clear");

            if ((clear != null) && clear.equals("true")) {

                ShoppingCart cart = (ShoppingCart) session.getAttribute("cart");
                cart.clear();
            }

            userPath = "/cart";


// if addToCart action is called
        if (userPath.equals("/addToCart")) {

            // if user is adding item to cart for first time
            // create cart object and attach it to user session
            if (cart == null) {

                cart = new ShoppingCart();
                session.setAttribute("cart", cart);
            }

            // get user input from request
            String productId = request.getParameter("productId");

            if (!productId.isEmpty()) {

                Product product = productFacade.find(Integer.parseInt(productId));
                cart.addItem(product);
            }

            userPath = "/category";


        // if updateCart action is called
        } else if (userPath.equals("/updateCart")) {

            // get input from request
            String productId = request.getParameter("productId");
            String quantity = request.getParameter("quantity");

            boolean invalidEntry = validator.validateQuantity(productId, quantity);

            if (!invalidEntry) {

                Product product = productFacade.find(Integer.parseInt(productId));
                cart.update(product, quantity);
            }

            userPath = "/cart";
