Best Solution
This error means that you're trying to access a lazily-loaded property or collection, but the hibernate session is closed. Lazy loading in Hibernate means that the object will not be populated (via a database query) until the property/collection is accessed in code. Hibernate accomplishes this by creating a dynamic proxy object that will hit the database only when you first use the object. In order for this to work, your object must be attached to an open Hibernate session throughout it's lifecycle. Check to see how you're managing your session. You may need to reattach objects to a new session if the session is being closed in some other place.
