Application specific log in tomcat 7 using JULI?

java, logging, tomcat

Solution

To configure JULI in the web applications you need have a `logging.properties` file in the `WEB-INF/classes` directory. If you use the default handlers, you may lose messages. You need to specify a prefix for the handler in your file.

handlers=1FILE.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
.handlers=java.util.logging.ConsoleHandler

1FILE.org.apache.juli.FileHandler.level=FINEST
1FILE.org.apache.juli.FileHandler.directory=/app-logs
1FILE.org.apache.juli.FileHandler.prefix=file-1

java.util.logging.ConsoleHandler.level=FINE
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

com.xyz.level=INFO
com.xyz.handlers=1FILE.org.apache.juli.FileHandler

com.abc.level=INFO
com.abc.handlers=java.util.logging.ConsoleHandler

A handler prefix (e.g. `1FILE.`) starts with a number, then has an arbitrary string, and ends with a period (.).

Arguments in the JVM

If you are not running the Tomcat from the `startup.sh` or `startup.bat`, you need to specify:

- The location of the general `logging.properties` for Tomcat (in the `conf` directory of Tomcat)

- The manager `org.apache.juli.ClassLoaderLogManager`. This is important because allows you to configure for each web application different loggin options. By default, a JVM process can only have a single configuration file.) ,

Similar to the next (I'm using eclipse):

-Djava.util.logging.config.file="C:\Users\Paul\workspaces\utils\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\conf\logging.properties" -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

By default, `java.util.logging` read the file that is included in the JDK or JRE, e.g.:

"C:\Software\jdk1.7.0_17\jre\lib\logging.properties"
