public interface: SessionBean [javadoc | source]

All Implemented Interfaces:
    EnterpriseBean

The SessionBean interface is implemented by every session enterprise Bean class. The container uses the SessionBean methods to notify the enterprise Bean instances of the instance's life cycle events.
Method from javax.ejb.SessionBean Summary:
ejbActivate,   ejbPassivate,   ejbRemove,   setSessionContext
Method from javax.ejb.SessionBean Detail:
 public  void ejbActivate() throws EJBException, RemoteException

    The activate method is called when the instance is activated from its "passive" state. The instance should acquire any resource that it has released earlier in the ejbPassivate() method.

    This method is called with no transaction context.

 public  void ejbPassivate() throws EJBException, RemoteException

    The passivate method is called before the instance enters the "passive" state. The instance should release any resources that it can re-acquire later in the ejbActivate() method.

    After the passivate method completes, the instance must be in a state that allows the container to use the Java Serialization protocol to externalize and store away the instance's state.

    This method is called with no transaction context.

 public  void ejbRemove() throws EJBException, RemoteException

    A container invokes this method before it ends the life of the session object. This happens as a result of a client's invoking a remove operation, or when a container decides to terminate the session object after a timeout.

    This method is called with no transaction context.

 public  void setSessionContext(SessionContext ctx) throws EJBException, RemoteException

    Set the associated session context. The container calls this method after the instance creation.

    The enterprise Bean instance should store the reference to the context object in an instance variable.

    This method is called with no transaction context.
