Questions tagged [catalina.out]

When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out.

When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out. The name is configurable using an environment variable. Whatever is written to System.err/out will be caught into that file. That may include:

  • Uncaught exceptions printed by java.lang.ThreadGroup.uncaughtException(..)
  • Thread dumps, if you requested them via a system signal

For more, please read: https://tomcat.apache.org/tomcat-7.0-doc/logging.html#Console

I have accidentally removed catalina.out and Tomcat doesn't recreate it

By default, Tomcat v7 was logging everything nicely to the catalina.out. When it got too big, I have removed it. Since then, the log file doesn't exist. I have tried creating it manually, but it stays there untouched.
