what are steps need to configure to implement Jboss scheduler in jboss4.0..2

A simple way to create a sceduler is to implement Schedulable interface, you have to implement public void perform(Date data, long l) method.
This interface is found in sceduler-plugin.jar, for jboss 4.0.5.

A sample cod is:

public class MyScheduler implements Schedulable
{
 public void perform(Date data, long l)
 {
 execute();
 }
}

and the deployment descriptor from jboss-service is:

<server>
 <mbean code="org.jboss.varia.scheduler.Scheduler"
 name="acme:service=Scheduler">
 <attribute name="StartAtStartup">true</attribute>
 <attribute name="SchedulableClass">MyScheduler</attribute>
 <attribute name="InitialStartDate">NOW</attribute>
 <attribute name="SchedulePeriod">60000</attribute>
 <attribute name="InitialRepetitions">-1</attribute>
 </mbean>
</server>

I hope it helps you.

And whart next?
Where & how do I include the xml file in the ear file ?

I'm trying to just print a text in the consile. So, execute() is
System.out.print("Listener called");

I included META-INF/scheduler-service.xml in the jar package.

I expect to see this message in the eclipse console, just after .ear deploy.

Am I correct ? What do I do wrong ?

Thank you very much.

OK. I found my problem:
2 files were to be added in META-INF
- scheduler-service.xml having the tag

<mbean code="org.jboss.varia.scheduler.Scheduler" ...>

described above

- jboss-app.xml with

<jboss-app>
 <module>
 <service>META-INF/scheduler-service.xml</service>
 </module>
</jboss-app>

And these 2 files must be added in eclipse packaging configuration page in the Project.ear node with the prefix META-INF

Finally works for me: a message appears at 3 secconds in the console window.

I did that with an existing Stateless bean of my application and it worked well untill I injected another bean with the @EJB annotation

then it couldnt deploy... NullPointerExeption...

i searched a lot... and tryed with SchedulableMBean instead... but I cant get things working...

it worked like this guy said... but how to make it work if the SchedulableClass is a bean... or have to import a bean?

Is it because your scheduler is deployed before the EJB is deployed? You may want to add a "depends" to your scheduler so it appears after jboss initializes it. Also, always post your stack traces.
