I've updated jboss-service.xml as follows:
<mbean code="org.jboss.varia.scheduler.Scheduler" name="jboss.docs:service=Scheduler"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">TestSchedule</attribute> <attribute name="SchedulableArguments">TheName,123456789</attribute> <attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">60000</attribute> <attribute name="InitialRepetitions">-1</attribute> </mbean>
