JMX bean which provides the functionality to change the log level of a class/package and to reload the log4j.properties during runtime.
I was facing the problem to change {{{log4j.properties}}} settings of classes/categories during runtime of an application. Additionally I wanted to have also the possibility to reset/reload the settings again like they was before. After studying log4j documentation I couldn't find only a half solution materialized as an jmx bean (http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/jmx/package-summary.html). After deeper google search for this issue, I found several hints how to solve this issue, which I would like to combine here.
