Use pattern for WS-Notification as an entry or exit point to the service integration bus

In addition to the ability to pass information between WS-Notification producers and consumers, the WS-Notification support provided in WebSphere® Application Server also acts as an entry or exit point to the service integration bus. Event notifications that are published by WS-Notification applications are inserted into the service integration bus where they can be modified, rerouted or consumed by any of the other applications that are connected to the bus. Equally, publications sent by service integration bus clients such as JMS can be received by WS-Notification consumers.

In the example below a WS-Notification publisher inserts into the notification broker an event notification that is received by a JMS message consumer. Conversely a JMS message producer can publish a message that is received by a notification consumer.

The following figure shows an application server. Attached to the application server is a notification broker and a JMS provider. There is a JMS message producer, a publisher, a notification consumer, and a JMS message consumer outside the application server. Messages pass from the publisher using SOAP over HTTP into the notification broker, through WebSphere Application Server to the JMS provider, and out using JFAP to the JMS message consumer. Messages also pass from the JMS message producer using JFAP into the JMS provider, through WebSphere Application Server to the notification broker, and out using SOAP over HTTP to the notification consumer.

This figure is described in the surrounding text.

For details of how messages inserted by JMS applications are viewed by WS-Notification applications, see Interacting with JMS message types.
