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:
