The advantage of using an EntityManager is that it doesn't tie Spring to Hibernate. EntityManager is used in JPA, which means that any JPA container (Hibernate, Toplink...) can be used for persistence.
as we know, if we use EntityManager we have to use the persistence.xml..
where do we have to put the persistence.xml?..
is it on OurApplication/WEB-INF/classes/META-INF ?
or is it on OurApplication/META-INF ?
