When I try to use the JDBC Connector I'm getting this error when I go to try and send a SQL.

I'm getting a weird error that I don't understand when trying to connect a JDBC request to an Oracle DB.

java.lang.AbstractMethodError: Receiver class oracle.jdbc.driver.T4CConnection does not define or inherit an implementation of the resolved method abstract isValid(I)Z of interface java.sql.Connection. at or

What's going on here? #jmeter

JDBC driver might be outdated. Does ojdbc8.jar exist in your Jmeter/lib directory?

If not, try downloading it to that directory from the link below. Then, re-start Jmeter and reattempt the connection.

You should add ojdbc7.jar to your Test Plan

You can click on Browse and add it, Save Test Plan and restart JMeter
