[jboss-user] [EJB/JBoss] - HASingleton Services on 4.0.4 not working

[markfrench]

Hi,

I have a number of schedulable services which need to run as HA Singletons.  I have added the following line to their service descriptors:

jboss.ha:service=HASingletonDeployer,type=Barrier

When I fire up jboss they are created but never scheduled at all.  Removing the above attribute and they run as expected.  The following are the service descriptors:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <server>
  |     <classpath codebase="lib" archives="scheduler-plugin.jar"/>
  |        
  |     <mbean code="org.jboss.varia.scheduler.Scheduler"
  |            name="eventmanager:service=FrequencyEventScheduler">

  |         <attribute name="StartAtStartup">true</attribute>
  |         <attribute name="SchedulableClass">com.transtoll.modules.eventmanager.schedulables.jboss.FrequencyEventSchedulable</attribute>
  |         <attribute name="InitialStartDate">NOW</attribute>
  |         <attribute name="InitialRepetitions">-1</attribute>
  |         <attribute name="SchedulePeriod">60000</attribute>

  |         <attribute name="SchedulePeriod">60000</attribute>
  |         <depends>eventmanager:service=initialisation</depends> 
  |     </mbean>
  |     
  |     <mbean code="org.jboss.varia.scheduler.Scheduler"
  |            name="eventmanager:service=MetricPersistenceScheduler">
  | <depend>jboss.ha:service=HASingletonDeployer,type=Barrier</depend>
  |         <attribute name="StartAtStartup">true</attribute>

  |         <depends>eventmanager:service=initialisation</depends> 
  |     </mbean>
  | </server>

Any thoughts as to what I'm doing wrong?

Cheers
