If I declared @GeneratedValue(strategy = IDENTITY) to an Id will this be generated automatically???

I am in an assumption that it creates automatically but throws the below error
Cannot insert the value NULL into column 'classification_id', table 'stack.x.classification'; column does not allow nulls. INSERT fails.

Code to insert

Code:

final EntityManager em = JPAUtil.getCurrentEntityManager();
    em.persist(classification);
    em.flush();
    em.clear();

Could someone please help.
