Solution

  • You're looking into wrong place, the class you're missing lives in com.ibm.mq.allclient jar.

    1. Download com.ibm.mq.allclient jar along with dependencies
    2. Put the libraries somewhere to JMeter Classpath
    3. Restart JMeter to pick the libraries up

    Also depending on your MQ server configuration you might need to do some coding exercise using JSR223 Sampler as JMeter JMS components most likely won't be suitable for your scenario. See IBM MQ testing with JMeter - Learn How article for more details and example configuration/code snippets.
