    Can I Turning off 'EJBTimerService' in JBoss 6.0 ?

    Kuntal Mondal Newbie

      Hi All,

      I am using "Jboss AS 6.0.Final" release with "default" configuration.

      I am not using 'EJBTimerService' in my J2EE application.

      Wondering is it possible to turn off or disable this service?


      My initial intention was to turn off 'Hypersonic DB' service - but to turn off that I have noticed that EJBTimerService needs that 'Hypersonic DB' service.

      So I tried to trun off EJBTimerService by removing "ejb2-timer-service.xml" from 'deploy' directory and by commenting  related entry in default\deployers\"ejb-deployer-jboss-beans.xml" file. But this did not help - all of my EJB deployment failed with:

      "** UNRESOLVED Demands 'jboss.ejb:service=EJBTimerService' **"


      So, I believe somewhere else in the configuration area we must have referred to the EJBTimerService - which I donot know.

      can anyone pls. suggest how to disable this service?


      By googling I find few similar discussions, but those are mostly applicable for JBoss 5.x release - not for the latest JBoss AS release.


      Thanks in advance,

          I suppose that the timer service is required by the deployment.

          If you don't need it remove the bean from the ejb2-timer-service.xml and use the commented section as shown below

            <mbean code="org.jboss.ejb.txtimer.NoopPersistencePolicy" name="jboss.ejb:service=EJBTimerService,persistencePolicy=noop"/>

            Thanks for the response.

            I followed your suggestion - but that did not help.


            I did comment out the related MBean code i.e. '<mbean code="org.jboss.ejb.txtimer.DatabasePersistencePolicy"'

            - but I still get deployment error.


            Looks like, the 'DatabasePersistencePolicy' is being invoked internally when JBoss starts up - so probably we cannot get rid of 'DatabasePersistencePolicy'.

              looks like different in JBoss6.

              There is another Timer (Tx aware) a bit below.

              Look to line 49 (default configuration), I attach my ejb2-timer-service.xml from the fresh 'default' deploy folder.

                Yes - that works!

                I tried similar combinations but not this one!

                THANKs a lot.
