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.

How to Build jberet-schedule

To clean and build:

mvn clean install 

How to Use jberet-schedule

• In Java SE applications:
  • include jberet-schedule-executor module in application classpath.
  • See tests using jberet-schedule-executor in Java SE environment.
• In Java EE or web applications deployed to JBoss EAP & WildFly:
  • include jberet-schedule-executor module and optionally jberet-schedule-timer module in application package.
  • Sample app using jberet-schedule-executor: wildfly-jberet-samples/scheduleExecutor
  • Sample app using jberet-schedule-timer: wildfly-jberet-samples/scheduleTimer
