Hi,

I'm developping web application and I would like run a scheduling service at JBoss startup.

I'm using JBoss 4.0.5 + Seam 1.1. My Eclipse project has been generated by using Seam-Gen tools.

[resources/META-INF/scheduler-service.xml] file :

<?xml version="1.0" encoding="UTF-8"?>
<server>
 <mbean code="org.jboss.varia.scheduler.Scheduler"
 name="task:service=Scheduler">
 <attribute name="StartAtStartup">true</attribute>
 <attribute name="SchedulableClass">com.application.intranet.tasks.Task</attribute>
 <attribute name="SchedulableArguments">aa,123456789</attribute>
 <attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute>

 <attribute name="InitialStartDate">NOW</attribute>
 <attribute name="SchedulePeriod">6000</attribute>
 <attribute name="InitialRepetitions">-1</attribute>
 <depends>jboss.j2ee:module=fmichaud.jar,service=EJB3</depends>
 </mbean>
</server>

[resources/META-INF/jboss-app.xml] file :

<jboss-app>
 <loader-repository>
 seam.jboss.org:loader=fmichaud
 </loader-repository>
 <module>
 <service>META-INF/scheduler-service.xml</service>
 </module>
</jboss-app>

My scheduled task class :

public class Task implements Schedulable {
 private final zLogger log = zLogger.getLogger(getClass());
 private String name;
 private long value;

 /** Accounts business service EJB. */
 @EJB
 private AccountsServiceImpl accountsService;

 public Task(String name, long value)
 {
 this.name = name;
 this.value = value;
 log.logBusinessEvent(LogLevel.INFO, "ctor, name: " + name + ", value: " + value);
 }

 public void perform(Date now, long remainingRepetitions) {
 Collection<Account> accountsList = accountsService.getEntries();
 }
}

I obtain next exception at JBoss startup :

09:35:53,066 ERROR [Scheduler$Listener] Handling a Scheduler call failed

In web application or with TestNG, EJB is running.
I tried to lookup jNDI EJB but nothing seems valid.
How to instantiate EJB 3.0 for calling from JBoss scheduler service ?

Thanks for any help.
Regards.
