Imagine the following scenario: An application is started using an initial Log4J configuration file at startup. Then the user opens a the GUI to create i.e. a new user. In the GUI you can now create a new category (and appenders) for the new user. It should also be possibly to change/delelete categories, appenders, kind-of appenders and priorities via the GUI. Now the question: if the change of configuration is done via a property file, this would need the following steps: 1- read the config file 2- read the data entered in the GUI 3- parse the config file and add the changes coming from the GUI 4- call property configurator to take effect of the changes 5- write the changed property file to disk, using PropertyPrinter isn' t there a shorter way, or is this workflow clever?
