Package org.jbpm.process.core.timer.impl

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.
