How to log in root project with Log4j

Question

I want to log in my project, but it is logging on my desktop by default. How can I fix it?

Here are the log4j.properties

log4j.rootLogger=DEBUG, stdout, FILE
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%-5p] (%F:%M:%L) %m%n

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=logs/joss.log

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=%d [%-5p] (%F:%M:%L) %m%n

Answer 1

Edit log4j.appender.FILE.File where you want to save location.

I think your project is located at your desktop so log4j is logging on your desktop because your log4j.properties is written by logs/joss.log

AS-IS

log4j.appender.FILE.File=logs/joss.log

TO-BE

log4j.appender.FILE.File=C:/LOGGING_FILES_DIRECTORY/LOG_FILE_NAME.log

or just change from absolute path to relative path like below properties value. Then the log file(=joss.log) will be saved in your project directory([project root]/logs/joss.log).

log4j.appender.FILE.File=./logs/joss.log

I resolve the problem, it was because of this:

In Tomcat run configurations, you can specify the working folder, which is normally parameter inside some Tomcat conf file.
