Hello,
everyone,
I'm not sure how I got this error but I got everything working fine now.
I guess it was because, I had more than the slf4j-api log jar type in my
libs. I removed it and it seems to get rid of the error.
Thank you.
eve

Example of the code I am using -
@SuppressWarnings("unchecked")
public List<Item> list() throws Exception {
EntityManager em = null;
EntityTransaction tx = null;
try {
em = JPAUtil.getEntityManagerFactory().createEntityManager();
tx = em.getTransaction();
tx.begin();
return em.createQuery("select item from Item as item").getResultList();
} catch (Exception e) {
e.printStackTrace();
throw e;
} finally {
if (tx != null) {
tx.commit();
}
if (em != null && em.isOpen()) {
em.close();
}
}
}
and
public class JPAUtil {
private static final EntityManagerFactory emf;
static {
try {
emf = Persistence.createEntityManagerFactory("shopping-cart");
} catch (Throwable ex) {
System.err.println("Initial EntityManagerFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static EntityManagerFactory getEntityManagerFactory() {
return emf;
}
}
This' a tutorial I am trying to get working -
