Thanks you, Yes, i have install latest version of Jmeter on Windowns 7 and install JVM for windows7, but when i start jmeter.bat, the Jmeter application does not working? Could you have any other.
I want to start using Jmeter for performance testing but I am unable to run it on my system. ClassNotFoundException occurs if: a) the jar containing the class definition is not present. B) there exists some duplicate definition of a class. The error: java.lang.ClassNotFoundException: org.apache.jmeter.JMeter means that the jar file is missing/corrupted, due to which you're getting this error message.

You can try these methods:. Check if this class is present in /lib/ext/ApacheJMetercore.jar. Check if this jar file is not broken. try to use fresh installation of last available jmeter version.
check integrity of downloaded jmeter archive against PGP or MD5 signatures. check that $JAVAHOME is defined and points to JDK 1.6.0 or higher.
