em is always null in my quartz scheduler, plz help.

[statelessbean]

Hello,
I implemented my opensymphony quartz in Seam 1.6.1 GA app using JBoss 4.0.5. For some reasons I don't want to use Seam asynchronous.
My problem is I always get em injected as null, why?

here is my copomenents.xml

<core:managed-persistence-context name="em"
auto-create="true" persistence-unit-jndi-name="java:/sguEntityManagerFactory" />

Scheduler listener

public class StartupListener implements ServletContextListener {

 public void contextInitialized(ServletContextEvent contextEvent) {
 SchedulerSystem obiektKlasyW = new SchedulerSystem();

 Thread watekPrzeliczniaCennika = new Thread(obiektKlasyW);

 watekPrzeliczniaCennika.start();

 }

 public void contextDestroyed(ServletContextEvent arg0) {}
}

public class SchedulerSystem implements Runnable {

 public void run() {
 SchedulerFactory schedFact = new rg.quartz.impl.StdSchedulerFactory();

 Scheduler sched = null;
 try {
 sched = schedFact.getScheduler();
 } catch (SchedulerException e) {
 e.printStackTrace();
 }

 try {
 sched.start();
 } catch (SchedulerException e) {
 e.printStackTrace();
 }

 //JobDetail jobDetail = new JobDetail("CennikJob", "groupCeniki", JobPrzeliczanieCennika.class);
 JobDetail jobDetail = new JobDetail("CennikJob", "groupCeniki", SchedulerJobs.class);

 Trigger trigger = TriggerUtils.makeSecondlyTrigger(2);
 trigger.setName("CennikiTrigger");
 trigger.setGroup("groupCeniki");
 trigger.setStartTime(new Date());


 try {
 sched.scheduleJob(jobDetail, trigger);
 } catch (SchedulerException e) {
 e.printStackTrace();
 }

 }//run()

}

and my job

public class SchedulerJobs implements Job {
 public SchedulerJobs() {}

 @In(create=true)
 protected EntityManager em;

 public void execute(JobExecutionContext kontekst) {
 Date date = new Date();
 //HERE i GET NULL my EM

 }
}

Can anyone help me, hot to create/inject well my em?

Probably because it's not a Seam component (needs @Name)

[statelessbean]

This didn't helped. I added @Name("simpleJob") to my jobs class and other annotations to all classes :
@Name("schedulerSystem") and @Name("schedulerJobs") and in
listener is em, in schedulerJobs also is em implemented, but in my thread "simpleJob" em is null.

In seam pay example that i previosly used simple asynchronous thread had em.

Is any way to inject/implement my em into thread manually?

If you want to access Seam outside a managed request (ejb3, jsf, async, ws) then you'll need to set up the contexts yourself - various Seam components do this. Much much easier to use Seam async.

Hi Pete,

I have the same problem. I created a subClass @override schedule method, which loads schedules from database. When I inject @In entityManager, it also got null. I don't have any idea how to deal with this situation. Could you please give some guidance? Thank you very much in advance.

@Override
 protected Collection loadEntries(Date startDate, Date endDate) {
 List selection = em.createQuery(
 "select ea.event from EventAttendee ea " +
 "where ea.attendee = :person")
 .setParameter("person", user)
 .getResultList();
 System.out.println("event size ===" + selection.size());
 return selection;
 }

Best wishes,

Gus
