Answer 1

You fetched an entity that has a one-to-many relationship represented in Java as a lazy-loaded Collection and you are trying to iterate over that collection after you have already closed the Hibernate session within which you have fetched the object. You must either fetch the collection eagerly or widen the session boundaries to enclose your iteration code.
