Configuring Log4j in my Web App

[s mahen perera]

Hi !!

I am developing a Web App using the Struts framework. Can someone pls tell me step by step what (like what is the jar required,,where to put the other configurations files etc )to do in order to configure Log 4j in it.

The end result should be to somehow display the log messages in the tomcat (The Sevlet Container i am using) console, for the log message i have given in the source code ,,, as for example.. logger.debug("log message");

You need to down load a copy of the latest log4j.jar file from Log4j logging services.

Place that Jar file to the WEB-INF/lib directory for each web application that you deploy.

Place your log4j.properties or your log4j.xml in the classpath of your web app ( usually in WEB-INF/classes).

Mahen,

Please see this post for a sample log4j.xml file. The discussion in that thread is related to what you are trying to do.
Good luck.
