The Event Mediator redirects incoming events to the specified event topic. For more information, see Working with Topics and Events.
The configuration options for Event Mediator are:
- Topic Type
- Topic - Topic to which the events are published. This can be a static topic, or can be specified using an XPath as a dynamic topic.
- Expression - XPath expression that builds the message to be published to the topic.
You can configure the Mediator using XML. Click on "switch to source view" in the "Mediator" window.
In this scenario, when an event notification comes to the
EventingProxy proxy service, they are processed by the
PublicEventSource sequence, which logs the messages and publishes them to the topic
SampleEventSource. Services that subscribe to the topic
SampleEventSource will then receive these messages.
