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.

Java’s Missing Byte Array Class

February 19, 2020 Roger Lacroix
s

After 25 years, it is still surprising that Java doesn’t have a proper byte array class. There can be many reasons that the data a Java program needs to work with is in a byte array. It could be the contents of a file or MQTT message or IBM MQ message, etc. Since there is […]

The person on StackOverflow made a comment that I was using a static string as my reply message. Humm. Some times people cannot see the forest for the trees. So, I have updated my sample Java/MQ (i.e. MQTest77.java) in this posting to do the following: Connect to a remote queue manager Open an input queue, […]

Request & Reply JMS/MQRFH2 Messaging Scenario

January 31, 2020 Roger Lacroix

Sometimes people over think a problem and write a complicated solution when really the solution is no different than any other Request/Reply scenario (use case). On StackOverflow, someone asked a question about sending a reply JMS/MQRFH2 message using the RFH2 header and folder values from the original request message. The code will copy the RFH2 […]

Today, I went to build (compile) and run a C# .NET/MQ sample that I have which worked perfectly before and I got the following error when I ran it: I compiled it again. No errors and it successfully generated the executable. Weird. When I ran it, I got the above error message. I searched the […]
