1. Re: Stateless and Stateful Beans with EntityManager
I dit not understand what you are asking for. Could you be a bit more specific?

2. Re: Stateless and Stateful Beans with EntityManager
Sorry let me explain with an example. You can use EnitytManager as:
@Stateful
public class Movies {
@PersistenceContext
private EntityManager entityManager;Or for example as:
@Stateless
public class Movies {
@PersistenceContext(unitName = "movie-unit", type = PersistenceContextType.EXTENDED)
private EntityManager entityManager;What do you think is the best option?

Hi Alex,
Below is the excerpt from JPA specification (Section 7.6.3 - Container managed Extended Persistence Context),
"A container-managed extended persistence context can only be initiated within the scope of a stateful
session bean."
You cannot have extended persistence context in stateless session bean.
Hope this has answered your question

Partly because if you are not using an extended persistence context, then Stateless is still valid.

Do we have any answer to this? I had a question on the similar lines java - @PersistenceContext With 'Provided' Scope RestController - Stack Overflow Any leads to this? Do have a look at this answer to java - Is EntityManager really thread-safe? - Stack Overflow
