Hi, I understand the current version of log4j is 2.x, but our company using log4j 1.x and so my question is specific to version 1.x:
It's said here http://logging.apache.org/log4j/2.x/manual/webapp.html that "You must take particular care when using Log4j or any other logging framework within a Java EE web application. It's important for logging resources to be properly cleaned up (database connections closed, files closed, etc.) when the container shuts down or the web application is undeployed. Because of the nature of class loaders within web applications, Log4j resources cannot be cleaned up through normal means. Log4j must be "started" when the web application deploys and "shut down" when the web application undeploys. How this works varies depending on whether your application is a Servlet 3.0 or newer<http://logging.apache.org/log4j/2.x/manual/webapp.html#Servlet-3.0>or Servlet 2.5 <http://logging.apache.org/log4j/2.x/manual/webapp.html#Servlet-2.5>web application." Questions: 1) How do I start Log4j? Did I miss something? Currently I'm using log for 4 in my jsp / java as follows: import or.apache.log4j.Logger; Logger log = Logger.getLogger("LoggerName"); log.error("msg"); 2) How do I "shut down" Log4j per above? If there is a service call that I have to make before and after Tomcat gets started, I am not aware. 3) What if I don't start / shudown Log4J correctly, what files / resources will remain and where is the resource located and how do I clean up the resource? 4) Since can redeploy my web app, this means I can go in and delete the whole tomcat temp directory AND whatever resources (files) that log4j uses... so what's the concern? Thank you, Gordon
