    Default How to display data from list into web browser with JSTL foreach loop ?

    I know it's complicated enough that what I need but it is much more complicated to explain, but I'll try

    So I made a list of types <data> and fill some of the data. Now I have to in .jsp file using JSTL technology and with foreach loop display this data in a servlet (in a web browser).

    In JSTL file I tried to <c:forEach items="${ requestScope['newList'] }" var="data"> but I simply couldn't print anything in the browser.

    I'm interested if someone could help me and explain more in detail the above line, and also what command should be added to the servlet.

    Thank you!

    Did, but still nothing. I think that problem is in my servlet. I'm sure that I did something wrong or didn't do something that I have to.

    here is the servlet code:

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub

    String username = request.getParameter("username");
    String password = request.getParameter("password");

    if(username.equals("student") && password.equals("password")){


    request.getSession().setAttribute("newList", Metoda.getGeneratedData());

    RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/kupovina.jsp");
    dispatcher.forward(request, response);


    /*request.setAttribute("novaLista", Metoda.getGeneratedData());*/

    }
    else{
    final String rez = "Login failed! Try Again!";
    request.setAttribute("Rezultat", rez);
    RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/login.jsp");
    dispatcher.forward(request, response);
    }
    }
