So, in my servlet, I simply need to write something like this:
| import java.io.*;
| import javax.servlet.*;
| import javax.servlet.http.*;
|
| public class SomeServlet extends HttpServlet
| {
|
| @PersistenceContext
| private EntityManager em;
|
| public void doGet(HttpServletRequest request,
| HttpServletResponse response)
| throws ServletException, IOException
| {
|
| List lista = em.createQuery("from Topologia").getResultList();
| ........
| ........
| ........
|
| }
| }
|
And It will work, right?
