Hello everyone,
I have an example of a simple app using the Data module of the deltaSpike
and following what it says in the link:
http://deltaspike.apache.org/documentation/jpa.html
but instead of using JPA I am using Data in TomCat .
my class manufactures this as in documentation:
public class JUGFactory {
@PersistenceContext
private EntityManager entityManager;
@Produces
@RequestScoped
public EntityManager createEntityManager()
{
return this.entityManager;
}
public void closeEntityManager(@Disposes EntityManager entityManager)
{
if (entityManager.isOpen())
{
entityManager.close();
}
}
}
but in this way when executing the action, he throws me an exception
(attached)
now it is left as follows:
@ApplicationScoped
public class JUGFactory {
@Produces
@RequestScoped
public EntityManager criarEntityManager() {
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("soujava-rio");
return emf.createEntityManager();
}
public void closeEntityManager(@Disposes EntityManager manager) {
manager.close();
}
}
it works normal .
thanks.
