Hi,
i am new to EJB 3.0 and jboss
i am trying to create a timer with this code taken from the j2ee documentation
| /**
| * TimerBean is a stateless session bean that creates a timer and prints out a
| * message when a timeout occurs.
| * Created Jan 9, 2006 3:44:08 PM
| * @author ian
| */
| @Stateless
| public class TimerSessionBean implements TimerSession {
| private static final Logger logger = Logger.getLogger(
|
"com.sun.tutorial.javaee.ejb.timersession.TimerSessionBean");
| @Resource
| TimerService timerService;
|
| public void setTimer(long intervalDuration) {
| Timer timer = timerService.createTimer(
| intervalDuration,
| "Created new timer");
| }
|
| @Timeout
| public void timeout(Timer timer) {
| System.out.println("Timeout occurred");
| }
| }
|
I get these errors...can someone help me?
I use the "4.5. EJB Timer Configuration" of the jboss configuraton guide
