Failed to load driver class Java::oracle.jdbc.driver.OracleDriver.

Either you've given it the wrong path to the jar, or the wrong jar.

No, same config is working when running logstash extracted from jar

singlahitesh commented 6 years ago

My config : output { jdbc { driver_jar_path => "/usr/share/logstash/ojdbc6.jar" driver_class => "Java::oracle.jdbc.driver.OracleDriver" connection_string => "" statement =>[ "some query"] } }

Docker image contents :

RUN mkdir /usr/share/logstash/log \ && /usr/share/logstash/bin/logstash-plugin install logstash-output-jdbc \ && /usr/share/logstash/bin/logstash-plugin update logstash-output-jdbc

Try removing the Java:: from your driver_class. That shouldn't be necessary.

Removing Java:: from driver class is working for jdbc output plugin. Surprisingly jdbc input plugin mentions to add Java:: in driver class for correct working of input plugin with ojdbc6.jar
