public class PersistenceFacade
extends java.lang.Object
We need this class to write some code in OpenXava that works in the same way if we are using Hibernate or EJB3 JPA (or other persistence technology).
This class can be used in custom application code, although for this case maybe it's better to use directly the EJB3 JPA (or Hibernate) API.
This class uses the underlayer persistence provider associated to the corresponding entity.
If the methods fail they throw RuntimeException
, the specific
RuntimeException
depends on the implementation technology.
