Lazy Load collection(one-Many) attribute and retriving after em.close()

Is there a way to lazy load a collection attribute in an entity and retrivie it after calling entityManager.close().Which i mean retrival out of the entity manager context.

Code template might look like this

EntityManager em = (retrive from factory)
SampleEntity se = em.find(SampelEntity.class,45);
em.close();
se.getXXXCollection() - Here i required a lazy loading to happen out of the enity manager context

It would ideally throw a "failed to lazily initialize a collection" exception but thought of getting some suggestions from the forum whether is there any solution.

Please suggest.

Thank you
