@vikasrjain @satishbhor I figured this one. Set your path Env variable to include only JDK bin path and "NOT" JRE path.

@callmkarthik Can you please specify HOW?

@shaialo I suppose this could help.
https://docs.oracle.com/javase/tutorial/essential/environment/paths.html

However, I am still in trouble how to run this test on a server where JDK is not installed? For instance, I have a client's staging server where JDK cannot be insalled, only JRE. Ideally this should be the situation.

How can I load test kafka using this library over there? I am always getting same exception due to pepper-box/src/main/java/com/gslab/pepper/input/compile/InMemoryJavaCompiler.java contains instance of java.tools.JavaCompiler, which references null when this code runs on machines with only JRE.

@aakashagarwal86 Having JDK is prerequisite for pepperbox to work. If your staging server cannot have jdk then you can also generate load from another machine in same network on staging server. I hope by staging server you mean Kafka staging server/application staging server.

I have the JDK included in the PATH, but I am still getting this error.

Hello,
I'm getting this error. I have the JDK in my path, and I've updated the jmeter.bat file to include the jdk path. Can anyone help?
