JBoss 6 M4" To view the discussion, visit: http://community.jboss.org/message/559624#559624 -------------------------------------------------------------- Hi! I'm building a simple session to test timers on JBoss 6 M4, //----------------------------------------------- package org.jboss.ejb3.timerservice.example; import java.util.Date; import javax.annotation.Resource; import javax.ejb.Stateful; //import javax.ejb.Stateless; import javax.ejb.Timeout; import javax.ejb.Timer; import javax.ejb.TimerService; import com.soteica.ots.scheduler.SchedulerRemote; @Stateful(name = "Scheduler") public class Scheduler implements SchedulerRemote {    @Resource    private TimerService timerService;    @Override    public void scheduleTask()    {       Date now = new Date();       Timer timer  = this.timerService.createTimer(now, 5000, "5SecondTimer");    }    @Timeout    private void onTimeout(Timer timer)    {       System.out.println("Timeout method invoked at " + new Date() + " for bean " + this.getClass().getSimpleName());    } } //----------------------------------------------- It works properlly is defined as Stateles, but if defined as stateful the following errors appear: 16:30:53,546  ERROR [STDERR] java.lang.RuntimeException: Unable to inject jndi  dependency: TimerService into property
