Class Log4jConfigurer

java.lang.Object

info.magnolia.logging.Log4jConfigurer

public class Log4jConfigurer
extends Object

Log4j initializer. Loads the file specified using the log4j.config init parameter and optionally set a system property containing the magnolia web application root directory with the name specified by the magnolia.root.sysproperty init parameter.

If magnolia.root.sysproperty is empty no system variable will be set; if log4j.config is empty no log4j initialization will be performed.

You can easily specify relative paths for log4j configuration files using the magnolia root system property, for example using ${magnolia.root}logs/magnolia-debug.log

Note: if you drop multiple magnolia wars in a container which doesn't isolate system properties (e.g. tomcat) you could need to change the name of the magnolia.root.sysproperty variable in web.xml and in log4j configuration files.

Some ideas and snippets borrowed from the more complex Spring implementation http://www.springframework.org
