I have the problem with running a script in JMeter. I get the following error message

Cannot load JDBC driver class 'oracle.jdbc.OracleDriver'

Does anyone know how to solve it?


  • Please provide more info (driver version, DB version, connection settings...) .

As per Let's Start chapter of JMeter Getting Started Guide

If you want to perform JDBC testing, then you will, of course, need the appropriate JDBC driver from your vendor. JMeter does not come with any JDBC drivers.

So make sure to download Oracle JDBC Driver and drop it to JMeter Classpath.

And don't forget to restart JMeter to pick the .jar up.

Also change "Validation Query" in the JDBC Connection Configuration to select 1 from dual

Copy the jars you want to use and drop in this location:


Then restart jmeter.
