what is the best way to receive log-events of another application running log4j.
my plan is, to create an application which shows all log-events fired by an runing application an for example use syntax highlighting an other stuff to help the user to read these events.
I would implement a custom log4j appender (extend org.apache.log4j.AppenderSkeleton). So you are able to recieve all LoggingEvent objects and have to update your UIs. If you want to have a persistent view you indeed have to save your recieved logging events into your database/your file system.
