After oracle java has become paid. I have Uninstalled oracle JDK and installed openJDK but now when I try to open JMeter, I get the following error: "Not able to find Java executable or version. Please check your Java installation. errorlevel=2" .. Can someone please let me know how do I make JMeter work with open JDK on my windows system.
I tried changing the path JAVA_HOME to point to open JDK but I still get same error.
No matter which JDK vendor/build you prefer (Oracle, Microsoft, Eclipse, Amazon, Liberica, whatever) you need to have java.exe executable in your operating system PATH
So if you do something like:
set PATH=c:\path\to\your\openjdk\installation\folder\bin;%PATH%
and then launch JMeter from that command prompt - it will be successful (hopefully). If it helps - you can add the above line to jmeter.bat startup script to make the change permanent or amend your PATH environment variable using any other way.
