    question concerning an Entity Manager and its associated JDB

    Mark Reynolds Newbie

      I'm working with a team on a application which uses Seam 2.1 with JBoss AS 5.0. We plan to use JPA with the Hibernate provider.

      I'm investigating at what point an entity manager actually obtains a JDBC connection from a pool and how long it holds onto the connection. Does the EM acquire a jdbc connection when it is instantiated and hold on to it for its full lifetime or does it only obtain a connection during persistent operations life find, persist, and during transactions?

      Is this behavior defined as part of the JPA spec or does the behavior vary by implementation?
