Andrea Gazzarini resolved QPID-1582.
------------------------------------
Resolution: Fixed
Hi all,
the last step (at the moment) of QMan is here : implementation on QMan of
WS-Notification.
As first version there are only two topics : one for lifecycle events of object
instances (create & remove) and one for lifecycle events (only create) of
events.
That means:
1) There are two topics : qman:ObjectsLifeCycleTopic and
qman:EventsLifeCycleTopic
2) QMan will publish on the first one the following message when (for example)
a connection is created :
<wsnt:NotificationMessage
xmlns:wsnt="http://docs.oasis-open.org/wsn/b-2";
xmlns:qman="http://amqp.apache.org/qpid/management/qman";
xmlns:qman-wsa="http://amqp.apache.org/qpid/management/qman/addressing";
xmlns:wsa="http://www.w3.org/2005/08/addressing";
xmlns:wsnt="http://docs.oasis-open.org/wsn/b-2";>
<wsnt:SubscriptionReference>
<wsa:Address
xmlns:wsa="http://www.w3.org/2005/08/addressing";>http://romagazzarini:8080/qman/services/SubscriptionManager</wsa:Address>
<wsa:ReferenceParameters
xmlns:wsa="http://www.w3.org/2005/08/addressing";>
<qman-wsa:ResourceId
xmlns:qman-wsa="http://amqp.apache.org/qpid/management/qman/addressing";>09c45414-1adf-4bf1-b855-71c9597176e0</qman-wsa:ResourceId>
</wsa:ReferenceParameters>
</wsnt:SubscriptionReference>
<wsnt:Topic
Dialect="http://docs.oasis-open.org/wsn/t-1/TopicExpression/Concrete";
xmlns:qman="http://amqp.apache.org/qpid/management/qman";>qman:EventsLifeCycleTopic</wsnt:Topic>
<wsnt:ProducerReference>
<wsa:ReferenceParameters
xmlns:wsa="http://www.w3.org/2005/08/addressing"/>
<wsa:Address
xmlns:wsa="http://www.w3.org/2005/08/addressing";>http://romagazzarini:8080/qman/services/adapter</wsa:Address>
</wsnt:ProducerReference>
<wsnt:Message>
<qman:LifeCycleEvent TimeMillis="1234295015000" Type="CREATED"
xmlns:qman="http://amqp.apache.org/qpid/management/qman";>
<qman:Resource>
<qman-wsa:ResourceId
xmlns:qman-wsa="http://amqp.apache.org/qpid/management/qman/addressing";>aff2f6ec-2e5c-4768-ae87-6da2c8a005ff</qman-wsa:ResourceId>
<qman:PackageName>org.apache.qpid.broker</qman:PackageName>
<qman:Name>connection</qman:Name>
</qman:Resource>
</qman:LifeCycleEvent>
</wsnt:Message>
</wsnt:NotificationMessage>
3) A similar notification (but with type="REMOVED") will be published when an
object instance (a connection for example) is removed
4) For events there are only CREATE notification. So on the second mentioned
topic a message will be published each time an "event" (for example a subscribe
event) is created on QMan (and therefore on Qpid)
Further improvement will be made in order to meet (eventual) management client
needs.
Best regards,
Andrea
