RE: [eclipselink-users] How to create EclipseLink Sessions, ORM.xml files in J2SE environment
|
Kris,
If you
are planning on using our Native API (Session, UnitOfWork, ReadAllQuery, ...)
instead of JPA (EntityManager, EntityManagerFactory, Query, ...) you do not need
to use any JPA XML files (i.e. persistence.xml). You can simply do your mappings
using the Workbench and use our native API as it sounds like you have experience
there.
As
indicated you can use JPA and access our native implementation when required.
Take a look at the JPAHelper class for some methods to un-wrap
sessions/UnitOfWork/Query objects when you need them.

Hi Tim
Thanks for taking the time for replying to my query. I still did
not get from the links you pointed me out of how to create sessions. I
see you are using entitymanagerfactory and entitymanager. I dont see
creatin any sessions and unit of works in these examples.
Can you help me with that?
Thanks
Kris
