import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


@WebServlet("/addServlet")
public class addServlet extends HttpServlet {
 private static final long serialVersionUID = 1L;
       
   
 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 
  PreparedStatement st1=null;
        Connection con; 
   
   
        PrintWriter out = response.getWriter();

   String  sname =request.getParameter("sname");
   String  course =request.getParameter("course");
   String addr =request.getParameter("address");
   String mobile =request.getParameter("mno");
   
  
  try

        con = DriverManager.getConnection("jdbc:mysql://localhost/lblschool", "root",""); 
  String query ="insert into student(sname,course,address,mno)values(?,?,?,?)";
  st1= con.prepareStatement(query);

  st1.setString(1, sname);
  st1.setString(2, course);
  st1.setString(3, addr);
  st1.setString(4, mobile);
  int k = st1.executeUpdate();


  if(k ==1)
    {
