We use Log4j2 in our project too. While your configuration is specified "log4j.properties", and ours in "log4j2.xml", I wonder if they are similar enough for comparison. I see that you define 2 appenders but no logger. The appenders define what Log4j2 resources are available, but did you tell it which appender to actually use - the logger? We also define both console and file appenders and enable/disable as required with the logger. As an analogy, you could compare defining Log4j2 resources with getting ready to paint. Each resource could be likened to a paint brush. The color and finish of the paint would be the layout and pattern. Maybe you defined a thick brush with blue matte paint as your console appender, and a thin brush with red gloss paint for the file appender. The logger keyword specifies which brush is in your hand. So without using the logger keyword, neither paint brush has been placed into the hand for actual use. The paint brushes (appenders) are just sitting there unused. Does that make sense? I wonder is some of the confusion with Log4j2 is the word "logger" - a generic term versus a keyword. Anyway, please note that I am not an expert in Log4j2, so all this could be complete BS. :-P HTH -- Cris Berneburg CACI Lead Software Engineer > -----Original Message----- > From: John Dale [mailto:jcdw...@gmail.com] > Sent: Wednesday, March 06, 2019 1:44 PM > To: Tomcat Users List > Subject: Re: Tomcat 8.5.13 - random issue with HTTPS (blank page) - working > good with HTTP > > Check your log4j configuration .. make sure it's got a console appender > configured (based on the log file names, it would seem like a console logger > will be required).
