1. Re: jboss sheduler issue
popoctavian Oct 12, 2007 3:06 AM (in response to mcjeevi)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. -
2. Re: jboss sheduler issue
cpetru Oct 12, 2007 7:54 AM (in response to mcjeevi)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. -
3. Re: jboss sheduler issue
cpetru Oct 12, 2007 9:57 AM (in response to mcjeevi)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. -
4. Re: jboss sheduler issue
rrupel Dec 13, 2007 7:47 AM (in response to mcjeevi)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?

genman Dec 13, 2007 9:53 PM (in response to mcjeevi)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.
