Hi all, I have implemented a servlet which can be included with my applications that allowed me to programmatically change logging properties on the file, for example ,Changing logging levels, adding loggers, showing all loggers either with explicit levels or not. My problem is that I would like to do *two* additional things with the servlet and I have no idea how to achieve them?: *1st* - I would like to reset loggers to the application defaults defined in my logback.xml file. Previously when I had implementation of this using Log4J I simply used the system property *log4j.configuration* to get hold of the file, then called *DOMConfigurator.configure(Loader.getResource(filename)) *which then reloaded the log4j config file. As I now do not set a system property I cannot work out how to get hold of the my logback.xml configuration file to re-load it, even if I got hold of it is there a way of resetting/reloading my configuration? *2nd* - Secondly in a similar context as part of my servlet I can explicitly add new loggers with new levels e.g. If I have the class * com.james.morgan.myapplication.Class123* which contains a logger I can override the default level for *com.james.morgan* and add a new logger *com.james.morgan.myapplication.Class123 *with a different level, however once I am finished the only way I can put the logger back to the default level is to set the new logger which I have added to the default level, what I what is the ability to delete a logger but again cannot find any documentation on this? Thanks for any help or suggestions with my problems, James
