JMeter - Webdriver error : java.lang.NoClassDefFoundError: com/sun/jna/platform/win32/Kernel32

Question

This error:

• jmeter log,

appears everytime I run a testscript in Jmeter. But everything works...

It is just this error that appears everytime in log after the actual script had run.

Can I ignore this error? Or will it influences my test?

Jmeter: 2.13
Java: 1.8.0.45
Jmeter Plugin : 1.3 (Standard,Extras,ExtraLibs, Webdriver)

Answer 1

Your issue is due to missing jar that contains :

• com/sun/jna/platform/win32/Kernel32

You should be able to download it with its dependency here:

• http://www.java2s.com/Code/Jar/j/Downloadjna330platformjar.htm
• http://www.java2s.com/Code/Jar/j/Downloadjna330jar.htm

And put it in jmeter/lib folder.
