Hi Florent, In Oxygen we use the Apache Log4j logging. So if in the Oxygen installation directory you create a "log4j.properties" file like the one I'm attaching you will be able to set up a logger in each class like: /** * Logger for logging. */ private static org.apache.log4j.Logger logger = org.apache.log4j.Logger.getLogger(CurrentClass.class.getName()); If you start Oxygen using the startup scripts like "oxygen.bat" you will see your messages in the console (either using the logger or writing to System.out or System.err directly).

Hi,

I was looking for the logging policy for plugins, but couldn't find it in the doc. Is there any way to setup and use logging in a Java plugin?

Regards,
