NotificationServiceshould register itself in the OSGi service registry as a service.
(String principal, int code, String correlator, AlertItem items) throws DmtExceptionSends a notification to a named principal. It is the responsibility of the
NotificationServiceto route the notification to the given principal using the registered
In remotely initiated sessions the principal name identifies the remote server that created the session, this can be obtained using the session's
The principal name may be omitted if the client does not know the principal name. Even in this case the routing might be possible if the Notification Service finds an appropriate default destination (for example if it is only connected to one protocol adapter, which is only connected to one management server).
Since sending the notification and receiving acknowledgment for it is potentially a very time-consuming operation, notifications are sent asynchronously. This method should attempt to ensure that the notification can be sent successfully, and should throw an exception if it detects any problems. If the method returns without error, the notification is accepted for sending and the implementation must make a best-effort attempt to deliver it.
In case the notification is an asynchronous response to a previous
executecommand, a correlation identifier can be specified to provide the association between the execute and the notification.
In order to send a notification using this method, the caller must have an
AlertPermissionwith a target string matching the specified principal name. If the
null(the principal name is not known), the target of the
AlertPermissionmust be "*".
When this method is called with null correlator, null or empty AlertItem array, and a 0 code as values, it should send a protocol specific default notification to initiate a management session. For example, in case of OMA DM this is alert 1201 "Client Initiated Session". The
principalparameter can be used to determine the recipient of the session initiation request.
principal- the principal name which is the recipient of this notification, can be
code- the alert code, can be 0 if not needed
correlator- optional field that contains the correlation identifier of an associated exec command, can be
nullif not needed
items- the data of the alert items carried in this alert, can be
nullor empty if not needed
DmtException- with the following possible error codes:
UNAUTHORIZEDwhen the remote server rejected the request due to insufficient authorization
ALERT_NOT_ROUTEDwhen the alert can not be routed to the given principal
REMOTE_ERRORin case of communication problems between the device and the destination
COMMAND_FAILEDfor unspecified errors encountered while attempting to complete the command
FEATURE_NOT_SUPPORTEDif the underlying management protocol doesn't support asynchronous notifications
SecurityException- if the caller does not have the required
AlertPermissionwith a target matching the
principalparameter, as described above
