Getting started with MQ on Java: Where to begin?

Question

I'm trying to kludge some legacy connectivity into one of our newer applications, and this marks my first foray into MQ. We have a middleware server that accepts an XML message delivered via MQ; converts this into a proprietary request for our ancient system of record, and then delivers a response on a reply queue in a similar XML format.

I have a sample of the input and output XML structure, and the MQ host, target queue, and reply queue. What I do not have is a clue as to where to begin.

Is there a decent tutorial available for building a simply request/response mechanism with OpenMQ or one of the other free MQ libraries?

Thanks!

Answer 1

The Oracle developers guide for OpenMQ would prob be a good place to start:

http://download.oracle.com/docs/cd/E19798-01/821-1796/index.html

Gives you example code, explains how to interact with it, etc.

Answer 2

I would suggest that you first get comfortable with the Java Message Service (JMS) concepts and API and then concentrate on the particulars of OpenMQ .

To learn about JMS, read the JMS chapter in Oracle's Java EE 6 Tutorial . The Manning book ActiveMQ in Action gives a good introduction to JMS concepts.

If you want to simplify your JMS code, consider using Spring JMS .

WebsphereMQ has an API tester - a demo application that allows you to experiment with the API and different features from a GUI

There's a similar tool for generic JMS providers called hermes
