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.
