Creating persistance layer with spring/hibernate?

There are many approaches to this. One solution I use is to use the javax.persistence. PersistenceContext annotation.

Spring will respect this annotation and inject a proxy to a thread local EntityManager Provided your DAO is created by Spring this allows access to the entity manager from within your DAO.

Public class DAO { private EntityManager entityManager; @PersistenceContext public void setEntityManager(EntityManager entityManager) { this.

EntityManager = entityManager; } }.

Repository public class MyDAO { @Autowired private SessionFactory sessionFactory; // ... } and add the MyDAO bean to the context XML file, or simply add the following lines to this file.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
