JMS Point to Point Jmeter Load Testing - NoInitialContextException

Question

I was trying to test JMS using Jmeter and was trying to run it in local, but keep getting the error: Response message: javax.naming.NoInitialContextException: Cannot instantiate class: org.apache.activemq.jndi.ActiveMQInitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.apache.activemq.jndi.ActiveMQInitialContextFactory]

I have already added the activemq-all.jar file in lib folder of jmeter, which should have resolved the issue, but it remains.

Please help me understand if I am missing something. Thanks.

Below is my jmx file content for the test plan:

Answer 1

Your test plan looks good, most probably you forgot one little step: you need to restart JMeter in order to pick up the new .jars from its classpath

If you want quickly test a .jar without JMeter restart you can add on Test Plan level
