| javax.ejb.SessionSynchronization
| SessionSynchronization | | public interface SessionSynchronization (Code) | | The SessionSynchronization interface allows a session Bean instance
to be notified by its container of transaction boundaries.
An session Bean class is not required to implement this interface. A
session Bean class should implement this interface only if it wishes to
synchronize its state with the transactions.

| Method Summary | |
| public void | afterBegin()
The afterBegin method notifies a session Bean instance that a new transaction has started, and that
the subsequent business methods on the instance will be invoked in the context of the transaction.
The instance can use this method, for example, to read data from a database and cache the data in
the instance fields.
This method executes in the proper 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 provide backwardcompatibility for enterprise beans written for the EJB 1.0 specification. | | public void | afterCompletion(boolean committed)
The afterCompletion method notifies a session Bean instance that a transaction commit protocol has
completed, and tells the instance whether the transaction has been committed or rolled back.
This method executes with no transaction context.
This method executes with no transaction context.
Parameters:
committed - - True if the transaction has been committed, false if is has been rolled back.
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 provide backwardcompatibility for enterprise beans written for the EJB 1.0 specification. | | public void | beforeCompletion()
The beforeCompletion method notifies a session Bean instance that a transaction is about to be committed.
The instance can use this method, for example, to write any cached data to a database.
This method executes in the proper transaction context.
Note: The instance may still cause the container to rollback the transaction by invoking the
setRollbackOnly() method on the instance context, or by throwing an exception.

| afterBegin | | public void afterBegin() throws EJBException, RemoteException(Code) | | The afterBegin method notifies a session Bean instance that a new transaction has started, and that

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 provide backwardcompatibility for enterprise beans written for the EJB 1.0 specification. Enterprise beans written for theEJB 1.1 and higher specifications should throw the javax.ejb.EJBException instead of this exception.Enterprise beans written for the EJB 2.0 and higher specifications must not throw the java.rmi.RemoteException. |
| afterCompletion | | public void afterCompletion(boolean committed) throws EJBException, RemoteException(Code) | | The afterCompletion method notifies a session Bean instance that a transaction commit protocol has
completed, and tells the instance whether the transaction has been committed or rolled back.
This method executes with no transaction context.
