MBean with Scheduler: IllegalArgumentException
Hello,
I want to create a MBean or stateless SessionBean, what has an method that should be called periodical e.g. every 10 second. I founded an example with modifying of scheduler-service.xml and created an interface and a MBean.
@Local
public interface TestExampleMBean extends ServiceMBean {
public void hitTest(int param);
}@Stateless
public class TestExample extends ServiceMBeanSupport implements TestExampleMBean {
public TestExample() {
super();
}
public void hitTest(int param) {
log.info("hitTest");
}
//..other methodes
}
scheduler-service.xml has following code
<mbean code="cosee.reporting.service.example.TestExample" name=":name=TestExample"> </mbean> <mbean code="org.jboss.varia.scheduler.Scheduler" name=":service=Scheduler,name=TestExample"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableMBean">:name=TestExample</attribute> <attribute name="SchedulableMBeanMethod">hitTest(int)</attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">10000</attribute> <attribute name="InitialRepetitions">3</attribute> <attribute name="FixedRate">true</attribute> </mbean>
I deploy my application and while scheduling calls of the method IllegalArgumentException is being thrown every time.
I checked the parameter, the parameter types should be correct.
Stake trace looks so:

I don't really know, what I do wrong.
