The classes from jars are automatically found by the Jmeter in the following directories:
JMETER_HOME/lib - used for utility jars
JMETER_HOME/lib/ext - used for JMeter components
One point to remember here is that you should jar any JMeter components developed by you and also you need to copy the jar into JMeter's lib/ext directory. JMeter components will be automatically found by the JMeter in any jars found here.
Furthermore you should define the property search_ paths in jmeter.properties in case you don't want to put the extension jars in the lib/ext directory. And also lib/ext is intended for JMeter components only and not for utility jars so don't use lib/ext for utility jars. Remember that other jars should be placed in the lib directory - not the lib/ext directory, jars like, JavaMail, JDBC, Beanshell etc.
