Dynamically change Logback level for web app running on tomcat

I have a logback.xml in the resources folder of my java web application which is running on Tomcat 7. Is there a way to change the debug level of some class of the application dynamically as the application is running?

The standard thing to do it is a normal java jar running from the CLI is to just edit logback.xml with say vim and after a while the log is updated. Is this possible with tomcat as I tried it and id does not seem to work.

Is there any better way?

You can try like this is your application to change the level:

Logger root = (Logger)LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
root.setLevel(Level.INFO);

For specifying the package name as logger-name.

LoggerContext loggerContext = (LoggerContext)LoggerFactory.getILoggerFactory();
Logger myPackageLogger = loggerContext.getLogger("com.mypackage");
myPackageLogger.setLevel(Level.INFO);
