org.nanocontainer.persistence.hibernate
Class SessionComponent

java.lang.Object
  extended by org.nanocontainer.persistence.hibernate.SessionComponent
All Implemented Interfaces:
Serializable, org.hibernate.Session, org.picocontainer.Startable
public class SessionComponent
extends Object
implements org.hibernate.Session, org.picocontainer.Startable

Session component with failover behaviour in case of hibernate exception. Old session is disposed and new one is obtained transparently. Session creation is done lazily.
