x        |  1@gmail.com  |   111111       |
y        |  2@gmail.com  |   222222       |
z        |  3@gmail.com   |  333333         |

index.jsp

<form action="profile.jsp" method="post">

    user name <input type="text" name="username"> </br> 
             <input type="submit" value="submit"></br>

</form>

profile.jsp

<form action="UserController" method="post">

    Phone Number <input type="text" name="phoneno"> <br>
    Email_id <input type="text" name="emailid"> <br>
    <input type="hidden" name="username" value="<%= request.getParameter("username") %>">
     <input type="submit" name="button1" value="next"> 
     <input type="submit" name="button1" value="previous">
</form>

UserController.java(servlet)

   protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {

        String button = request.getParameter("button1");
        String phoneno = request.getParameter("phoneno");
        String emailid = request.getParameter("emailid");
        String uname = request.getParameter("username");

        User user = new User();
    user.setUname(uname);
    user.setMail(mail);
    user.setContactno(contactno);
    ArrayList<User> al = new ArrayList<User>();
    al.add(user);
    request.setAttribute("info", al);
    if (button.equals("Next")) {
        RequestDispatcher rd = request.getRequestDispatcher("result.jsp");
        request.setAttribute("userinfo", al);
        rd.forward(request, response);

    } else if (button.equals("Previous")) {
        RequestDispatcher rd = request.getRequestDispatcher("index.jsp");
        rd.forward(request, response);
    }
}

I will bring all the textbox value in the servlet but I don't how to print the value in the result JSP page,

result JSP page should be

    username          |  Email id     |    Contact No  |
