MUHAMMAD MASHIUR RAHMAN [https://community.jboss.org/people/mashiur.rahman] created the discussion "Barrier service restart and dependency injection" To view the discussion, visit: https://community.jboss.org/message/729625#729625 -------------------------------------------------------------- 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 17:05:27,150 INFO  [org.jboss.ejb3.EJBContainer] (http-0.0.0.0-8080-1) STOPPED EJB: adactus.diactus.cluster.ejb.service.SingletonBarrierService ejbName: SingletonBarrierService 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.. 2012-04-12 16:56:39,174 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1) installing bean: diactus:service=singletonBarrierService 2012-04-12 16:56:39,174 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)   with dependencies: 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)   and demands: 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jboss.j2ee:ear=clusterTest.ear,jar=clusterTestEJB.jar,name=SingletonBarrierService,service=EJB3 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jboss.ejb:service=EJBTimerService 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    persistence.unit:unitName=clusterTest.ear/clusterTestEJB.jar#clusterTestEJB 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jboss.ha:service=HASingletonDeployer,type=Barrier 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)   and supplies: 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    Class:adactus.diactus.cluster.ejb.service.HASingletonServiceRemote 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    Class:adactus.diactus.cluster.timer.StaticEJBTimerOwner 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jndi:clusterTest/SingletonBarrierService/local-adactus.diactus.cluster.timer.StaticEJBTimerOwner 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jndi:clusterTest/SingletonBarrierService/remote-adactus.diactus.cluster.ejb.service.HASingletonServiceRemote 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jndi:clusterTest/SingletonBarrierService/remote 2012-04-12 16:56:39,175 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1)    jndi:clusterTest/SingletonBarrierService/local 2012-04-12 16:56:39,176 INFO  [org.jboss.ejb3.deployers.JBossASKernel] (http-0.0.0.0-8080-1) Installing bean(diactus:service=singletonBarrierService) into kernel 2012-04-12 17:04:48,980 INFO  [org.jboss.ejb3.EJBContainer] (http-0.0.0.0-8080-1) STARTED EJB: adactus.diactus.cluster.ejb.service.SingletonBarrierService ejbName: SingletonBarrierService 2012-04-12 17:04:49,005 INFO  [org.jboss.ejb3.proxy.impl.jndiregistrar.JndiSessionRegistrarBase] (http-0.0.0.0-8080-1) Binding the following Entries in Global JNDI:         clusterTest/SingletonBarrierService/remote - EJB3.x Default Remote Business Interface         clusterTest/SingletonBarrierService/remote-adactus.diactus.cluster.ejb.service.HASingletonServiceRemote - EJB3.x Remote Business Interface         clusterTest/SingletonBarrierService/local - EJB3.x Default Local Business Interface         clusterTest/SingletonBarrierService/local-adactus.diactus.cluster.timer.StaticEJBTimerOwner - EJB3.x Local Business Interface 2012-04-12 17:04:49,013 INFO  [STDOUT] (http-0.0.0.0-8080-1) SingletonBarrierService starting 2012-04-12 17:04:49,013 INFO  [STDOUT] (http-0.0.0.0-8080-1) SingletonBarrierService started But no dependency is being injected. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/729625#729625] Start a new discussion in EJB3 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
