[News.eclipse.technology.eclipselink] Re: JPA and Shared Cache

[jamesssss@xxxxxxxxx (James)]

The JPA EntityManager is more similar to the classical EclipseLink 
UnitOfWork than an EclipseLink Session, so it does make working copies of 
the shared cached objects.

However you can still access instances from the shared cache through JPA.  
There is a JPA query hint "eclipselink.return-shared" that gives you 
read-only objects from the shared cache.
