Overview

This module provides support for scheduling batch job executions in batch applications. It contains 2 sub-modules that provides 3 types of batch job scheduler:

  • jberet-schedule-executor sub-module
    • scheduler based on java.util.concurrent.ScheduledExecutorService, suitable for Java SE applications.
    • scheduler based on jakarta.enterprise.concurrent.ManagedScheduledExecutorService, suitable for Java EE applications.
  • jberet-schedule-timer sub-module
    • scheduler based on EJB Timer

Other types of job scheduler implementations are also possible by extending org.jberet.schedule.JobScheduler.

ScheduledExecutorService-based JobScheduler can be configured with:

  • a custom ManagedScheduledExecutorService JNDI lookup name (Java EE app only);
  • a java.util.concurrent.ConcurrentMap<String, JobSchedule> to store all job schedules;
  • fully-qualified name of the implementation class of JobSchedue.
