--------------------------------------------------------------
I have a service depends on jboss.ha:service=HASingletonDeployer,type=Barrier
When I stop the Barrier from jmx-console, my service also stopped and destroyed as well. 
Then if I start the barrier from jmx-console, the create method of the service is called two times then start method is called but jboss doesn't inject any dependency.

   @Resource
    public TimerService timerService;

    @Resource
    public SessionContext sessionContext;


    @PersistenceContext
    public EntityManager mEm;

   From service start method I found timerService,mEm, sessionContext everything is null.  Can anyone please help me why this is happening?

 When I stop the barrier from jmx-console, I get follwing messages in my log  

2012-04-12 17:05:27,141 INFO  [STDOUT] (http-0.0.0.0-8080-1) SingletonBarrierService stopped

2012-04-12 17:05:27,151 INFO  [STDOUT] (http-0.0.0.0-8080-1) SingletonBarrierService destroyed


Then if start again I get the messages below..
