The log file? Did you mean the config file (log4j.properties)?
I meant the log4j.properties, yes. But probably I misread the original question, which asked about the log file. Meaning the output from log4j, I suppose. I make log4j write that outside the web application.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
