My entityManager.persist(entity) not is throwing PersistenceException

Question

I'm using Netbeans IDE and EclipseLink JPA implementation.

According to Netbeans, this code is valid:

public void save(T entity) {        
    EntityManager entityManager = JPAUtil.getEntityManager();
    entityManager.getTransaction().begin();
    entityManager.persist(entity);
    entityManager.getTransaction().commit();
}

But I think, that really valid code is:

public void save(T entity) throws PersistenceException {        
    EntityManager entityManager = JPAUtil.getEntityManager();
    entityManager.getTransaction().begin();
    entityManager.persist(entity);
    entityManager.getTransaction().commit();
}

Why this is happening?

Answer 1

PersistenceException extends RuntimeException. This means that is an "unchecked" exception so it does not have to be explicitly declared or handled.
