import dao.Student;

@Controller
public class GuestController {
@RequestMapping("index")
public String home1()
{
return "home";
}
@RequestMapping("reglogic")
public ModelAndView reg1(HttpServletRequest request,HttpServletResponse response)
{
Configuration cfg = new Configuration();
cfg.configure("hibernate.cfg.xml");
SessionFactory sf = cfg.buildSessionFactory();
Session s = sf.openSession();
Transaction tx = s.beginTransaction();
Student st = new Student();
st.setMobileno(request.getParameter("txtmobile"));
st.setFname(request.getParameter("txtfname"));
st.setCoursename(request.getParameter("txtcourse"));
st.setEmail(request.getParameter("txtemail"));
