Re: [eclipselink-users] Problem with Transactions using EclipseLink
|
The indicates that Spring never began a transaction on the EntityManager. It
seems that Spring may have issues running in OSGi, or you don't have things
configured correctly.
You can begin a JPA transaction yourself, using em.getTransaction().begin().
My guess as to what is occurring is that Spring is getting confused on the
context, and it starting a transaction in one EntityManager, but not the
EntityManager it is injecting. You may wish to try the Spring forum.
Attaching an EclipseLink log on finest may help.
The other log showed EclipseLink beginning and committing a transaction, but
seemed to be on a different EntityManager than the persist was called on.
Also check your logs for any errors.
