Hello guys, I am using Hibernate + Spring with netbeans to make a web application. I have it working correctly and displaying data from the DB. My problem is I only know how to do one hibernate query which is shown below.

How can I do insert/delete queries. For instance in my JSP page I have a button, how can I make it so when a user clicks on a button it deletes a specific record from the database. In essence how can I pass parameters to my controller. and can someone explain when/how I need to use DAO objects.

public class TestimonialsController implements Controller {

    public ModelAndView handleRequest(HttpServletRequest hsr, HttpServletResponse hsr1)
        throws Exception

        ModelAndView bc = new ModelAndView("testimonials");
        String out = new String ("testimonial list");

        try {
            Session session = HibernateUtil.getSessionFactory().getCurrentSession();
            List result= session.createQuery("from Testimonial").list();
            bc.addObject("testimonials", result);
        } catch (Exception e) {

        bc.addObject("message", out);
        return bc;
