how to add javascript language to JSR223 Sampler language selection option in Jmeter application

Question

I have created a code in javascript language to display data in the database, I use the Jmeter application to see the performance of the database and use JSR223 Sampler.

but when I choose the language option there is no option for javascript language.

for that please give me instructions to add javascript language options in JSR223 Sampler Jmeter application

Answer 1

JavaScript language support has been removed in OpenJDK 15 so the options are in:

1. Downgrade your JVM to the previous version. The lowest version you can run JMeter with is Java 8.
2. Use alternative JVM like GraalVM
3. Switch to another language. Using JavaScript is some form of a performance anti-pattern, it's recommended to use Groovy language for scripting. More information: Beanshell vs. JSR223 vs. Java For JMeter: Complete Showdown
