| Method Summary | |
| void | ejbActivate()
A container invokes this method when the instance is taken out of the
pool of available instances to become associated with a specific EJB
object. | | void | ejbLoad()
A container invokes this method to instruct the instance to synchronize
its state by loading it state from the underlying database. | | void | ejbPassivate()
A container invokes this method on an instance before the instance
becomes disassociated with a specific EJB object. | | void | ejbRemove()
A container invokes this method before it removes the EJB object that is
currently associated with the instance. | | void | ejbStore()
A container invokes this method to instruct the instance to synchronize
its state by storing it to the underlying database. | | void | setEntityContext(EntityContext ctx)
Set the associated entity context. | | void | unsetEntityContext()
Unset the associated entity context. |
| ejbActivate | | void ejbActivate() throws EJBException, RemoteException(Code) | | A container invokes this method when the instance is taken out of the
pool of available instances to become associated with a specific EJB
object. This method transitions the instance to the ready state. This
method executes in an unspecified 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. |
| ejbLoad | | void ejbLoad() throws EJBException, RemoteException(Code) | | A container invokes this method to instruct the instance to synchronize
its state by loading it state from the underlying database. This method
always executes in the transaction context determined by the value of the
transaction attribute in the deployment descriptor.
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) | | A container invokes this method on an instance before the instance
becomes disassociated with a specific EJB object. After this method
completes, the container will place the instance into the pool of
available instances. This method executes in an unspecified 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 RemoveException, EJBException, RemoteException(Code) | | A container invokes this method before it removes the EJB object that is
currently associated with the instance. This method is invoked when a
client invokes a remove operation on the enterprise Bean's home interface
or the EJB object's remote interface. This method transitions the
instance from the ready state to the pool of available instances. This
method is called in the transaction context of the remove operation.
throws:
RemoveException - The enterprise Bean does not allow destruction ofthe object.
throws:
EJBException - The enterprise Bean does not allow destruction ofthe object.
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. |
| ejbStore | | void ejbStore() throws EJBException, RemoteException(Code) | | A container invokes this method to instruct the instance to synchronize
its state by storing it to the underlying database. This method always
executes in the transaction context determined by the value of the
transaction attribute in the deployment descriptor.
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. |
| setEntityContext | | void setEntityContext(EntityContext ctx) throws EJBException, RemoteException(Code) | | Set the associated entity context. The container invokes this method on
an instance after the instance has been created. This method is called in
an unspecified transaction context.
Parameters:
ctx - An EntityContext interface for the instance. The instanceshould store the reference to the context in an instance variable.
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. |
| unsetEntityContext | | void unsetEntityContext() throws EJBException, RemoteException(Code) | | Unset the associated entity context. The container calls this method
before removing the instance. This is the last method that the container
invokes on the instance. The Java garbage collector will eventually
invoke the finalize() method on the instance. This method is called in an
unspecified 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.
