Runtime changes to log4j.properties

[Jaikiran Pai]

Hi,
We have an application packaged as a ear file. This ear file contains a log4j.properties file meant for our application. Is there any way that the changes to log4j.properties, when the application is running, be picked up. Is this possible in Websphere? I would like the changes to be picked up without having to redeploy the application or restart the server.

Thanks in advance.

Jaikiran,
You definitely don't need to redeploy. I think you do need to restart the application though. If you are using clones, you can restart one clone at a time.

Thanks, Jeanne Boyarsky, for that answer.

To pick up the changes from log4j.properties file without restarting or redeploying the app, use

PropertyConfigurator.configureAndWatch(log4j.properties);

in your init() method.It will look for any changes in properties file, for every 60 sec(default), you can also change the timings.
