My name is Roger Lacroix and I am a die hard programmer. I have been programming since the 80s. My favorite programming languages are Java, C and Rexx. I have worked in the airline, retail but I have spent most of my time doing middleware work in the financial services industry. In 1994, I was introduced to IBM MQ (aka WebSphere MQ & MQSeries) and I thought it was the next best thing since man created fire. This blog will be about IBM MQ, Java, C, Rexx and any other interesting items that I can think of. I hope you enjoy it.

The other day, someone emailed me and asked if I could add code to externalize the default values used by the SimpleLogger Class. I thought about it and figured it would be reasonably straight forward.

My SimpleLogger can be a Replacement for Log4J

In this blog post, don’t get me wrong, I think Log4J is a great product and I am not trying to discourage anyone from using it. I have used Log4J v1.x on hundreds of projects for customers and myself. It has always worked exactly as expected. I have never used Log4J v2.x, so I cannot/will […]
