I'm trying to set up a scheduled task and I've read all the various docs I can find and I'm still having a problem. I'm running JBoss 3.2.2. When I start up JBoss I get the following:

14:51:17,487 WARN [ServiceConfigurator] Failed to complete install

I've added the scheduler-plugin.jar to my classpath. My class implements org.jboss.varia.scheduler.Schedulable, and has a perform() method. The constructor has no arguments. It is in a jar file that is in the deploy directory and is specified in the classpath. I have a scheduler-service.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<server>
 <mbean code="org.jboss.varia.scheduler.Scheduler" name="TradeRanger:service=Scheduler">
 <attribute name="StartAtStartup">true</attribute>
 <attribute name="SchedulableClass">com.tr.infrastructure.connectors.pollers.C1Connector</attribute>
 <attribute name="InitialStartDate">NOW</attribute>
 <attribute name="SchedulePeriod">300000</attribute>
 <attribute name="InitialRepetitions">-1</attribute>
 </mbean>
</server>
