| javax.ejb.EntityBean
| EntityBean | | public interface EntityBean extends EnterpriseBean(Code) | | The EntityBean interface is implemented by every entity enterprise
Bean class. The container uses the EntityBean methods to notify the
enterprise Bean instances of the instance's life cycle events.
|
| Method Summary | |
| public 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. | | public void | ejbLoad()
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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. | | public void | ejbPassivate()
A container invokes this method on an instance before the instance becomes disassociated with
a specific EJB object. | | public void | ejbRemove()
A container invokes this method before it removes the EJB object that is currently associated
with the instance. | | public void | ejbStore()
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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. | | public void | setEntityContext(EntityContext ctx)
Set the associated entity context. | | public void | unsetEntityContext()
Unset the associated entity context. |
| ejbActivate | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| ejbLoad | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| ejbPassivate | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| ejbRemove | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| ejbStore | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| setEntityContext | | public 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 instance should store thereference to the context in an instance variable.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 specification should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB2.0 and higher specifications must throw the javax.ejb.EJBExceptioninstead of this exception. |
| unsetEntityContext | | public 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.
exception:
EJBException - - Thrown by the method to indicate a failure caused by a system-level error.
exception:
java.rmi.RemoteException - - This exception is defined in the method signature to providebackward compatibility for enterprise beans written for the EJB 1.0 specification.
