HttpServletRequest request = ServletActionContext.getRequest();HttpServletResponse response=ServletActionContext.getResponse();HttpSession session=request.getSession();Session sess = MySessionFactory.getSessionFactory().getCurrentSession();Transaction tx = sess.beginTransaction();Query q1=sess.createQuery("from Category");List<Category> list=q1.list();tx.commit();request.setAttribute("listCategory", list);return "addArticle";
