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.

Updated SimpleLogger Class

December 22, 2021 Roger Lacroix

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. Hence, here are the JVM Environment variables that the SimpleLogger Class supports: SimpleLogger.LogFileName – any valid file name SimpleLogger.LogDirectory – […]

My SimpleLogger can be a Replacement for Log4J
