[jboss-user] [EJB 3.0 Users] - MBean with Scheduler: IllegalArgumentException

[myklynysh]

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:
