mq-swift-demo

This repository contains a small java demo program that connects to a IBM MQ queue manager and sends SWIFT MT103 messages. It was used to create a semi-realistic messaging demo that was used when demonstrating connecting IBM MQ with Watsonx to process message data.

Building the demo program

To build the java program you must have access to the IBM MQ java libraries. It is then built using:

$ cd src\swiftdemoapp
$ javac *.java

IBM MQ configuration

The demo program makes an assumption about the IBM MQ queue manager configuration. It will connect to a queue manager running on localhost:1414 using channel IN. It will not provide a TLS connection or user credentials. Once connected it will access the following 3 queues. BANKROB.Q, BANKGRA.Q and BANKNICK.Q.

Demo program usage

The demo program is ran by the following command, you must have access to the IBM MQ java libraries:

$ cd src 
$ java -cp ".;<path to IBM MQ install>\java\lib\com.ibm.mq.allclient.jar" swiftdemoapp.Main

Example SWIFT MT103 message

Below is an example of the MT103 messages that are sent and received by the demo program.
