Hi,
Can someone explain the meaning of the highlighted Java statement in the
following code especially the meaning of the @ sign in front of the
PersistenceUnit? Thanks.
import database.BookDBAO;
import javax.servlet.*;
import util.Counter;
import javax.ejb.*;
import javax.persistence.*;
public final class ContextListener
implements ServletContextListener {
private ServletContext context = null;
@PersistenceUnit
EntityManagerFactory emf;
Regards,
Peeterbrunch
