Modifying java.util.logging.SimpleFormatter format property under Tomcat

Question

I am using Tomcat 7.0.28, running under OpenJDK 1.7 on Ubuntu, and am trying to modify the formatting string used by java.util.logging.SimpleFormatter. According to the Jav

Answer 1

Don't know if this will solve your problem, but it may be worth a try. I was seeing the same behavior, although in my case I was doing the logging setup programmatically instead of using properties. Turns out that the property value for java.util.logging.SimpleFormatter.format needs to be set BEFORE constructing the (in my case) FileHandler. I was setting it after constructing the FileHandler, but before constructing SimpleFormatter. I wonder if, in your properties file, defining java.util.logging.SimpleFormatter.format BEFORE defining any of the Handler properties will solve the problem.

Answer 2

java.util.logging.SimpleFormatter.format is indeed documented to be settable in either logging.properties -which does not work for me either- or as a command line argument (java option).

The command line argument appears to work for me. Because the $JAVA_OPTS variable is going through so much tampering and ends up in eval, this is how I solved it (on Debian, java 1.7.0_07, apache-tomcat-7.0.30)

$CATALINA_HOME/bin/catalina.sh (line 230):

JAVA_OPTS="$JAVA_OPTS \"-Djava.util.logging.SimpleFormatter.format=%1\\\$tY-%1\\\$tm-%1\\\$td %1\\\$tH:%1\\\$tM:%1\\\$tS.%1\\\$tL %4\\\$s %3\\\$s %5\\\$s%6\\\$s%n\""

Answer 3

Thanks to info in the bug report pointed out by nolan6000 I finally got this working with tomcat-juli.

Instead of:

java.util.logging.SimpleFormatter.format=%4$s: %5$s [%1$tc]%n

it has to be:

1catalina.java.util.logging.SimpleFormatter.format=%4$s: %5$s [%1$tc]%n

Answer 4

You may be witnessing this bug.

The bug is fixed from Tomcat version 7.0.41 onwards as well as 6.0.38 onwards.

Answer 5

Using a formatter pattern in default Tomcat 8 JULI logger needs this, you may put arguments to a global $tomcat/conf/logging.properties or webapp specific $tomcat/webapps/myapp/WEB-INF/classes/logging.properties file.

This is my global file where have also disabled a manager-webapp logging files. Logging line is:
