de.enflexit.db.hibernate.HibernateUtilities

public class HibernateUtilities
extends java.lang.Object

The class HibernateUtilities provides static access to Hibernate SessionFactories that are distinguished by an ID. This allows to use the hibernate bundle for several purposes and from different bundles and their contexts and databases. if the argument factoryID is null, a 'defaultFactory' will be used.
