IBM MQ, Java and MQ MI and/or MQ HA

April 8, 2020 Roger Lacroix

Sometimes you come across things that make you just scratch your head and say who the hell wrote this @#$% code. I’m not trying to say that I’m the world’s greatest programmer but some of the shit that the MQ/Java team writes just makes my head spin. They need to share what they’re smoking! IBM’s […]

memmem() Function for a C Program

March 17, 2020 Roger Lacroix

Last week, I needed a function for a C program that would search a string not null terminated for a string not null terminated. Hence, I could not use strstr() function because it requires the strings to be null terminated. So, I checked my trusty C Runtime Library Reference and found nothing that matched. Now […]

Java’s Missing Byte Array Class

February 19, 2020 Roger Lacroix

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 […]

Updated Request & Reply JMS/MQRFH2 Messaging Scenario

February 3, 2020 Roger Lacroix

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

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 […]
