Interface RemoteCancellableExecutable

All Superinterfaces:

Executable, RemoteExecutable, Serializable

public interface RemoteCancellableExecutable
extends RemoteExecutable

Contract by which a client EJB executable can also be cancelled. This interface is typically implemented by ESS-EJB implementation when both execution and cancellation of a job is required.

When a EJB job request is cancelled, Oracle Enterprise Scheduler determines if the job class implements the RemoteCancellableExecutable interface, and if so, calls the cancel method to notify the client class of the request cancellation.

The job implementation is responsible for stopping the remote execution.
