Applications often require sending recurring or timed notifications. This can be done by creating a timer component that has a producer connected to a channel:
public class SomeTimer implements Runnable {
@Producer(target="SomeChannel")
protected Channel channel;
public void run() {
Event event = ...
channel.publish(event);
}
}
Further, to limit timed events to a highly-available single source in a clustered zone (i.e. a clustered singleton), mark the implementation with @Scope("DOMAIN"):
@Scope("DOMAIN")
public class SomeTimer implements Runnable {
@Producer(target="SomeChannel")
protected Channel channel;
public void run() {
Event event = ...
channel.publish(event);
}
}
