    HasSingleTonDeployer error in clustered jboss on slave node starting

    Mohan B.P Newbie

      I have clustered two jboss appservers with JBoss 5.1.0, JDK 6 and RHEL. I am getting following error when starting the second node at the end of startup  and first node is already running.

       

      Deployment "<UNKNOWN jboss.j2ee:ear=ear-BeyondBP-239732.ear,jar=abd-beyondbp.jar,name=SearchManagerImpl,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'jboss.ha:service=HASingletonDeployer,type=Barrier' **, ** UNRESOLVED Demands 'jndi:ear-BeyondBP-239732/StatusManagerImpl/local-com.ness.search.StatusManager' **, ** UNRESOLVED Demands 'jndi:ear-BeyondBP-239732/ThrottlerImpl/remote-com.ness.throttle.Throttler' **

        Deployment "<UNKNOWN jboss.j2ee:ear=ear-BeyondBP-239732.ear,jar=dean-beyondbp.jar,name=ThrottlerImpl,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'jboss.ha:service=HASingletonDeployer,type=Barrier' **

        Deployment "<UNKNOWN jboss.j2ee:ear=ear-BeyondBP-239732.ear,jar=scheduler-beyondbp.jar,name=SchedulerImpl,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'jboss.ha:service=HASingletonDeployer,type=Barrier' **

       

      However when only one node is running , or when i stop the first node  and if i run in single server every thing seems to be work fine. I am not understanding why HASingletonDeployer  service is not getting deployed  in a clustered environment and only while starting the second node. I am relatively new to jboss without much prior experience in JBOSS. I have not coded the part using HASingletonDeployer  service and I have very little idea on the working of HASingletonDeployer  . I am just deploying the .ear   and I have to resolve this. Can any body please help me in this regard as this has got me in to a deep fix.

      Please let me know if any body need any more information on this
