Class JobManagerService

java.lang.Object

com.sun.enterprise.v3.admin.JobManagerService

All Implemented Interfaces:

JobManager, EventListener, org.glassfish.hk2.api.PostConstruct

@Service(name="job-manager")
 @Singleton
public class JobManagerService
extends Object
implements JobManager, org.glassfish.hk2.api.PostConstruct, EventListener

This is the implementation for the JobManagerService The JobManager is responsible 1. generating unique ids for jobs 2. serving as a registry for jobs 3. creating threadpools for jobs 4.removing expired jobs
