Method Detail

bindIntoCorbalocService

public void bindIntoCorbalocService()
                             throws org.omg.CORBA.ORBPackage.InvalidName

Bind the NotificationService into the Corbaloc Service

Throws:

org.omg.CORBA.ORBPackage.InvalidName - if "CorbalocService" is an invalid name (i.e., never thrown)

bindIntoNamingService

public void bindIntoNamingService()
                           throws org.omg.CORBA.ORBPackage.InvalidName,
                                  org.omg.PortableServer.POAPackage.ServantNotActive,
                                  org.omg.PortableServer.POAPackage.WrongPolicy,
                                  org.omg.CosNaming.NamingContextPackage.AlreadyBound,
                                  org.omg.CosNaming.NamingContextPackage.CannotProceed,
                                  org.omg.CosNaming.NamingContextPackage.InvalidName,
                                  org.omg.CosNaming.NamingContextPackage.NotFound

Bind the EventChannelFactory to the Naming Service. Knowledge of the location of the Naming Service is the responsibility of the ORB.

Throws:

org.omg.CORBA.ORBPackage.InvalidName - should never be thrown, since "NameService" is always a valid initial reference key.

org.omg.CosNaming.NamingContextPackage.AlreadyBound - if a race condition exists and another request succeeds in binding a Notification Service to the naming service.

org.omg.CosNaming.NamingContextPackage.CannotProceed - if the naming service implementation has given up for some reason.

org.omg.CosNaming.NamingContextPackage.InvalidName - should never be called as "NotificationService" is a valid id and "" is a valid kind.

org.omg.CosNaming.NamingContextPackage.NotFound - if a race condition exists and another request has deleted the existing Notification Service.
