Problem on involving Timer component
I tried to use camel Timer component to do a regular call. It works with following configuration but always got a exception whenever server rebooted.
Could anyone help on resolving this annoy exception?
Below are the configuration in switchyard.xml and correspoding java code:
------------------------------------------------------------------------------------------------------------
<service name="TimerService" promote="TimerService">
<camel:binding.camel configURI="timer://myTimer?period=20s" />
</service>
------------------------------------------------------------------------------------------------------------
import java.util.Date;
import org.switchyard.component.bean.Service;
@Service(TimerService.class)
public class TimerServiceImpl implements TimerService{
public void checkInterval(){
System.out.println("now: "+new Date());
}
}
------------------------------------------------------------------------------------------------------------
When starting deploying into Switchyard AS, exception is like below:
