Information about programming MQTT clients

IBM MQ Telemetry Transport format and protocol
IBM MQ Telemetry Transport (MQTT) is a lightweight publish/subscribe protocol flowing over TCP/IP to connect large numbers of remote sensors and control devices. MQTT is used by specialized applications on small footprint devices that must tolerate low bandwidth and unreliable communication. We can use MQTT client apps from a business partner, or write your own client apps to use the published protocols. We can get sample client apps and supporting libraries from the Eclipse Paho project.
MQXR properties
MQXR property settings are stored in a platform-specific properties file: mqxr_win.properties or mqxr_unix.properties. You normally configure these properties by using MQSC admin commands or IBM MQ Explorer.
AuthCallback MQXR class
AuthCallback is the sole class in package com.ibm.mq.mqxr. It specifies the interface definition that a telemetry server administrator needs when they write an AuthCallback in the MQXR server.
