Java/PCF Program to Create an IBM MQ Queue

May 3, 2022 Roger Lacroix

The other day, someone on StackOverflow asked about creating an IBM MQ queue from JMS. I know it is possible to send PCF commands as a JMS message to the Command Server but it seems overly complex when you can simply do it from Java/PCF (non-JMS). If you are used to creating an IBM MQ […]

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 – […]
