| javax.ejb.SessionBean
| SessionBean | | public interface SessionBean extends EnterpriseBean(Code) | | 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 Summary | |
| void | ejbActivate()
The activate method is called when the instance is activated from its
"passive" state. | | void | ejbPassivate()
The passivate method is called before the instance enters the "passive"
state. | | void | ejbRemove()
A container invokes this method before it ends the life of the session
object. | | void | setSessionContext(SessionContext ctx)
Set the associated session context. |
| ejbActivate | | void ejbActivate() throws EJBException, RemoteException(Code) | | 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.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
RemoteException - This exception is defined in the method signatureto provide backward compatibility for enterprise beans writtenfor the EJB 1.0 specification. Enterprise beans written for theEJB 1.1 specification should throw the javax.ejb.EJBExceptioninstead of this exception. Enterprise beans written for theEJB2.0 and higher specifications must throw thejavax.ejb.EJBException instead of this exception. |
| ejbPassivate | | void ejbPassivate() throws EJBException, RemoteException(Code) | | 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.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
RemoteException - This exception is defined in the method signatureto provide backward compatibility for enterprise beans writtenfor the EJB 1.0 specification. Enterprise beans written for theEJB 1.1 specification should throw the javax.ejb.EJBExceptioninstead of this exception. Enterprise beans written for theEJB2.0 and higher specifications must throw thejavax.ejb.EJBException instead of this exception. |
| ejbRemove | | void ejbRemove() throws EJBException, RemoteException(Code) | | 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.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
RemoteException - This exception is defined in the method signatureto provide backward compatibility for enterprise beans writtenfor the EJB 1.0 specification. Enterprise beans written for theEJB 1.1 specification should throw the javax.ejb.EJBExceptioninstead of this exception. Enterprise beans written for theEJB2.0 and higher specifications must throw thejavax.ejb.EJBException instead of this exception. |
| setSessionContext | | void setSessionContext(SessionContext ctx) throws EJBException, RemoteException(Code) | | 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.
Parameters:
ctx - A SessionContext interface for the instance.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
RemoteException - This exception is defined in the method signatureto provide backward compatibility for applications written forthe EJB 1.0 specification. Enterprise beans written for the EJB1.1 specification should throw the javax.ejb.EJBException insteadof this exception. Enterprise beans written for the EJB2.0 andhigher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
