Serwlet który ma to odpalić
@WebServlet("/index")
public class index extends HttpServlet {
private static final long serialVersionUID = 1L;
private static EntityManagerFactory emf;
EntityManager em;
public index() {
super();
// TODO Auto-generated constructor stub
}
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
emf = Persistence.createEntityManagerFactory("hib");
em = emf.createEntityManager();
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
}
}
