Good Day All !! Thanks for the replies with regards configuring Log4J. I've chosen to use a xml config file (after doing some experimenting with properties files). Hmm....I should probably add that to my last post. I've encountered a new hiccup. My code uses the DOMConfigurator in the following fashion: DOMConfigurator.configureAndWatch("log4j.xml"); Here's the hiccup, when I make changes to my file, they are not picked-up until I re-start Tomcat. Any ideas ? I've done a little research, and haven't found anything related to bugs on this. Is there something I'm missing ? S
In a J2EE application server, servlets may be unloaded at any time. You know that before that happens, the destroy() method is called, so you can clean up any background threads.
The Log4J thread that does that however, is not cleaned up. Or at least there is no guarantee of that. Thus it is unsafe.
However, you can use the configuration methods of Log4J also to REconfigure: start that background thread to signal changes in the logging configuration yourself. You can then make sure that background thread is stopped the the servlet initiating it is destroyed.
