Hello,
When migrating @Service POJOs from JBoss AS 4.2.3 to 5.1.0, I ran into a
problem (bug?) with EJB timers (among others, more about those later in
separate posts) . Simplified example:
DummyService.java:
package example;
|
| public interface DummyService
| {
| void start()
| throws Exception;
| }
DummyServiceBean.java:
package example;
|
| import java.util.Date;
|
| import javax.annotation.Resource;
| import javax.ejb.Timeout;
| import javax.ejb.Timer;
| import javax.ejb.TimerService;
|
| import org.jboss.ejb3.annotation.Management;
| import org.jboss.ejb3.annotation.Service;
|
| @Service
| @Management(DummyService.class)
| public class DummyServiceBean
| implements DummyService
| {
| @Resource
| protected TimerService timerService;
|
| public void start()
| throws Exception
| {
| timerService.createTimer(new Date(), 5000, "DUMMY");
| }
|
| @Timeout
| public void timeout(Timer timer)
| {
| System.out.println("PING");
| }
| }
This works with AS 4.2.3 (annotation packages obviously changed to the old
ones), but the createTimer() fails in 5.1.0 with an InvocationTargetException
whose root cause is:
Caused by: java.lang.IllegalStateException: Cannot obtain inMethodFlag for:
TimerService.createTimer
| at
org.jboss.ejb.AllowedOperationsAssociation.assertAllowedIn(AllowedOperationsAssociation.java:145)
| at
org.jboss.as.ejb3.timerservice.TimerServiceFacade.assertAllowedIn(TimerServiceFacade.java:59)
| at
org.jboss.as.ejb3.timerservice.TimerServiceFacade.createTimer(TimerServiceFacade.java:64)
| at example.DummyServiceBean.start(DummyServiceBean.java:24)
| [...]
I don't remember seeing any instructions except the annotation package changes
in the 5.x release notes for migrating @Service POJOs. Ideas?
