Hi,
This is my index.jsp page

HTML Code:

<body>

        <h1>Login: </h1>

        <form name="myForm" action="getPassword" method="POST">

            Name <input type="text" name="uName" value="" /><br />

            Password: <input type="password" name="uPass" value="" /><br />

           Address <input type="text" name="uAddress" value="" /><br />

            Phone <input type="text" name="uPhone" value="" /><br />

            Email <input type="text" name="uEmail" value="" /><br />

        

            <input type="submit" name="btSubmit" value="Send" />

        </form>



    </body>

>>>>>and this is my servlet <<<<<

Code:

protected void processRequest(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

        response.setContentType("text/html;charset=UTF-8");

        PrintWriter out = response.getWriter();

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

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

        

        if(uPhone ?????????){

            RequestDispatcher dispatcher =

            getServletContext().getRequestDispatcher("/Correct.jsp");

            dispatcher.forward(request, response);

             return;

            

            

        }else{

            RequestDispatcher dispatcher =

            getServletContext().getRequestDispatcher("/Wrong.jsp");

            dispatcher.forward(request, response);

        return;

        }

>>>
I want to A Servlet that:
- checks the phone number has only numbers and no characters
- checks if the email address has '@' (at) symbol and a '.' (dot) in it

What should I wrote in ???? place

Oh lazy people I already found the answer for the first part which is the phone, I will write it just in case someone will use it:

PHP Code:


		
			
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        
         String uPhone = request.getParameter("uPhone");
         String uEmail= request.getParameter("uEmail");
        
        
       
        char[] chars = new char[uPhone.length()];
        uPhone.getChars(0, chars.length, chars, 0);
        for (int i = 0; i < chars.length; i++) {
          if (!('0' <= chars[i] && chars[i] <= '9')) {
            RequestDispatcher dispatcher =
            getServletContext().getRequestDispatcher("/Wrong.jsp");
            dispatcher.forward(request, response);
            
          }
          
        }
        RequestDispatcher dispatcher =
            getServletContext().getRequestDispatcher("/Correct.jsp");
            dispatcher.forward(request, response);
             
    }

but please I need the solution for the other part which is E-mail validity check
