Annotation Type BeforeCompletion


@Target(value=METHOD)
@Retention(value=RUNTIME)
public @interface BeforeCompletion

Designate a stateful session bean method to receive the before completion session synchronization callback.

The before completion callback notifies a stateful session bean instance that a transaction is about to be committed.

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 session context or by throwing an exception. A bean must have at most one BeforeCompletion method. The signature of this method must observe the following rules:

This method executes with no transaction context.

A stateful session bean class may use either the SessionSynchronization interface or the session synchronization annotations, but not both.

Since:
EJB 3.1
