Purpose:¶
This application demonstrates how to configure WSO2 Streaming Integrator Tooling to receive events to the SweetProductionStream
via WebSocket transport in XML default format and log the events in LowProductionAlertStream
to the output console.

* ReceiveWebSocketInXMLFormat.siddhi - Started Successfully!
Viewing the Results:¶
See the output. Following message would be shown on the console.
