tomcat 8.0x java.util.logging.Logger.log to file

Question

I'm using

private static final java.util.logging.Logger LOGGER = java.util.logging.Logger.getLogger(MyClass.class.getName());
LOGGER.log(Level.INFO, "log message);

style to log in my java web application.

I start tomcat 8.0.21 from startup.bat (project requirement) on windows 10. I can see all the logging in console window, including java.util.logging.Logger.log logging. But I can't see any java.util.logging.Logger.log logging in tomcat standard log files - %tomcat%/logs/catalina.2018-07-31.log and localhost.2018-07-31.log.

I can see all the tomcat logging, but not my web application logging. I need to track some problems with my web application on client machines in production, because I can't model such problems on my local computer.

I need to see my logging along with other tomcat logging in %tomcat%/logs/catalina.<current_date>.log. It would be better to to use tomcat logging configuration for all the projects. But using a per-project configuration is acceptable too. I have Googled the whole day, but all the recipes I found did not work for me.

Please don't offer to use log4j. Using java.util.logging is a project requirement. Here is my %tomcat%/conf/logging.properties file

mycompany.package1.level = ALL
mycompany.package2.level = ALL
utils.jaxws.level = ALL

Answer 1

From your logging.properties it looks like you are try to set the level for package of loggers:

mycompany.package1.level = ALL
mycompany.package2.level = ALL
utils.jaxws.level = ALL

You can only set the level of a logger if it has been created in code. Specify all of the exact logger names or in code you have to create and hold a strong reference to the mycompany.package1 and mycompany.package2 loggers.

private static final Object loggerParent = java.util.logging.Logger.getLogger("mycompany.package1");
private static final java.util.logging.Logger LOGGER = java.util.logging.Logger.getLogger(MyClass.class.getName());
