Jboss itself use log4j for logging.All j2ee applictions deployed under it share the same Log4j configuration and output their log to the same file.It's very unconvenient to monitor some application.If there are serveral busy j2ee applications deployed under one jboss server,it become difficult to distinguish their log.
I wan to make each web application use its own log4j configuration,so their log will not mixed each other(It's important for me!).I am new ,i can not get any clue from it's documentation.

please tell me how to make it out! Tks
