Detach an entity from JPA/EJB3 persistence context

Question

What would be the easiest way to detach a specific JPA Entity Bean that was acquired through an EntityManager. Alternatively, could I have a query return detached objects in

Answer 1

As far as I know, the only direct ways to do it are:

1. Commit the txn - Probably not a reasonable option
2. Clear the Persistence Context - EntityManager.clear() - This is brutal, but would clear it out
3. Copy the object - Most of the time your JPA objects are serializable, so this should be easy (if not particularly efficient).
