Log configuration

[saurav]

Hi All,

How do i configure Loggers for the Spring based application.Like log4j or commons logging?.

I see one class in org.springframework.util.Log4jConfigurer.
Do i have to define properties for this class in the applicationContext.xml.
But it is an abstract class is there any extension for this.

Please help

Thanks,
Saurav

	<!-- Load log4j first so that logger can be used by other services -->
	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>

Configure your web.xml

<context-param>
	<param-name>log4jConfigLocation</param-name>
	<param-value>/WEB-INF/properties/log4j.xml</param-value>
</context-param>
<listener>
	<listener-class>
		org.springframework.web.util.Log4jConfigListener
	</listener-class>
</listener>

log4j.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
