when I configure schedule-manager-service.xml and I boot jboss application server I have an error about dependence and so it don't deploy the SingleScheduleProvider mbean. But if I deploy schedule-manager-service.xml when jboss is started I haven't this problem. SingleScheduleProvider mbean need to activate the DefaultPartition for clustering. Indeed org.jboss.varia.scheduler.SingleSchedulerProvider extends indirectly org.jboss.ha.jmx.HAServiceMBeanSupport that throws an Exception if it don't find almost a cluster in the system. The problem is resolved add a <depends> tag in the schedule-manager-service.xml so:

<mbean code="org.jboss.varia.scheduler.SingleScheduleProvider"
name="jboss:service=SingleScheduleProvider">
<depends>jboss:service=ScheduleManager</depends>
<depends>jboss:service=SchedulableMBeanExample</depends>

<!--------- new update -------->
<depends>jboss:service=${jboss.partition.name:DefaultPartition}</depends>
<!--------- end update --------->

<attribute name="ScheduleManagerName">jboss:service=ScheduleManager</attribute>
<attribute name="TargetName">jboss:service=SchedulableMBeanExample</attribute>
<attribute name="TargetMethod">hit( NOTIFICATION, DATE, REPETITIONS, SCHEDULER_NAME, java.lang.String )</attribute>
<attribute name="DateFormat">hh:mm:ss</attribute>
<attribute name="StartDate">19:47:12</attribute>
<attribute name="Period">1000</attribute>
<attribute name="Repetitions">1</attribute>
</mbean>
