Again, the link is: https://logging.apache.org/log4j/2.x/manual/webapp.html Follow it slavishly until you get things working. You really need to follow the documentation on where to place log4j2.xml and how that file is found. http://logging.apache.org/log4j/2.x/manual/configuration.html In particular, pay attention to Automatic Configuration, item 9. I recommend this until you do a little more reading / research, and understand how things work. That's why I recommended to place log4j2.xml in WEB-INF/classes or in a JAR file in WEB-INF/lib. It's then on the web application classpath. No other configuration is necessary. In particular, pay attention to what happens when you do not configure log4j2 correctly, notably Automatic Configuration, item 10. 10. If no configuration file could be located the DefaultConfiguration will be used. This will cause logging output to go to the console. This will dump your log output to the console, which ends up in catalina.out when running in Tomcat. > > > Thanks, > > > On Wed, Aug 10, 2016 at 11:59 AM, Mark Eggers <its_toas...@yahoo.com.invalid >> wrote: > >> Syed, >> >> On 8/9/2016 10:08 PM, Syed Mudassir Ahmed wrote: >>> I am using Log4j in my web app to write the logs to a separate file. >>> Surprisingly, that log file is not at all getting created.
