Given class XX is not instance of Schedulable
Hi,
hope some can help me with this, because I couldn't find anything with the search engine here. I try to use the JMX timer service 'org.jboss.varia.scheduler.Scheduler' to send events to one of my classes. For this purpose I modified the example of paragraph '10.4.1. org.jboss.varia.scheduler.Scheduler' of
http://docs.jboss.org/jbossas/jboss4guide/r2/html/ch10.html
But when I start JBoss I get following error:
org.jboss.deployment.DeploymentException: Exception setting attribute javax.management.Attribute: name=SchedulableClass value=com.sykon.dss.TestTimer on mbean transactionMonitor:service=Scheduler; - nested throwable: (java.security.InvalidParameterException: Given class com.sykon.dss.TestTimer is not instance of Schedulable)

My TestTimer.class looks as follows:
import org.jboss.varia.scheduler.Schedulable;
public class TestTimer implements Schedulable
{
private static Logger log = Logger.getLogger( com.sykon.dss.etl.TestTimer.class.getName() );
private String name;
private long value;
public TestTimer(String name, long value)
{
this.name = name;
this.value = value;
log.info("ctor, name: " + name + ", value: " + value);
}
public void perform(Date now, long remainingRepetitions)
{
log.info("perform, now: " + now +
", remainingRepetitions: " + remainingRepetitions +
", name: " + name + ", value: " + value);
}
}
which is exactly the same class as in the example (apart from the class name)
My jboss-service.xml looks as follows:
<server> <mbean code="org.jboss.varia.scheduler.Scheduler" name="transactionMonitor:service=Scheduler"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">com.sykon.dss.TestTimer</attribute> <attribute name="SchedulableArguments">TheName,123456789</attribute> <attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">10000</attribute> <attribute name="InitialRepetitions">-1</attribute> </mbean> </server>
which is also the same as in the example, apart from the class name.
What am I missing? Can someone help with this, please? Any help appreciated!
