        String p=request.getParameter("upassword");
        String e=request.getParameter("uemail");
        String c=request.getParameter("ucountry");

        try

            psmt.setString(2, p);
            psmt.setString(3, e);
            psmt.setString(4, c);



            int i=psmt.executeUpdate();

            if(i>0)
            {
                pw.println(n);
                pw.println(p);

            }

        }

        catch(Exception ex)
        {
            System.out.println(ex);
        }

        pw.close();
