## Class QuartzSchedulerService

- java.lang.Object
- - org.jbpm.process.core.timer.impl.QuartzSchedulerService

- All Implemented Interfaces:
    org.drools.core.time.InternalSchedulerService, org.drools.core.time.SchedulerService, GlobalSchedulerService

      public class QuartzSchedulerService
      extends Object
      implements GlobalSchedulerService

  Quartz based `GlobalSchedulerService` that is configured according to Quartz rules and allows to store jobs in data base. With that it survives server crashes and operates as soon as service is initialized without session being active.
