This Java source code provides an API implementation for the client side of the protocol for Java to connect to WBI Brokers using Telemetry Transport.
WebSphere MQ Telemetry Transport (MQTT - previously called MQIsdp protocol) is a lightweight Publish/Subscribe protocol which can be used for integrating devices with WebSphere MQ brokers:
• WebSphere Business Integration Message Broker (formerly WebSphere MQ Integrator Broker)
• WebSphere Business Integration Message Broker with R&F extension (formerly WebSphere MQ Integrator)
This Java source code provides an API implementation for the client side of the protocol for Java.
A WebSphere MQ brokers SCADAInput node needs to be added to a message flow to provide the server side of the protocol.
MQTT is suitable for integrating devices such as embedded systems, systems connected by high cost communications, or systems connected by low bandwidth connections

Users of this SupportPac should have a good understanding of WebSphere MQ brokers and Publish/Subscribe concepts, as well as a good understanding of Java.
