The logger.properties file allows you to
set logger attributes for specific loggers. The properties file is loaded
the first time the method Logger.getLogger(loggername) is
called within an application.
When an application calls the
Logger.getLogger method
for the first time, all the available logger properties files
are loaded. Applications can provide logger.properties files in:
- the META-INF directory of the JAR file for the application
- directories included in the class path of application module
- directories included in the application class path
The properties file contains two categories of parameters - Logger
control and Logger data:
- Logger control information
- minimum localization level - minimum LogRecord level for which localization
will be attempted
- group - logical group that this component belongs to
- eventfactory - The Common Base Event template file to use with the event
factory. Note that the naming convention for this template is the fully qualified
component name, with a file extension of “.event.xml”. For example, a template
that applies to package com.ibm.compXYZ would be called com.ibm.compXYZ.event.xml
- Logger data information
- product name
- organization name
- component name
- extensions – additional properties
Sample logger.properties file
In the following
sample, event factory com.ibm.xyz.MyEventFactory will be used by any loggers
in the com.ibm.websphere.abc package or any sub-packages which do not override
this value in their own configuration file.
com.ibm.websphere.abc.eventfactory=com.ibm.xyz.MyEventFactory
