Configure log4j in Weblogic10.3

For Configuring log4j in Weblogic 10.3 follow below steps:

1) Place log4j-1.2.16.jar in your project build path.

2) put log4j.xml in your domain directory ( you can make any folder for ex. 'configuration')

3) There are many ways to initilize log4j, here I am including two ways

  a) Edit the server start up script
     Open $DOMAIN_HOME\bin\setDomainEnv.cmd and set LOG4J_CONFIG_FILE with complete path of log4j.xml. For example if you have placed log4j.xml under configuration folder.
set LOG4J_CONFIG_FILE=%DOMAIN_HOME%\configuration\log4j.xml

b) With Spring framework 
If you are using Spring framework in your application then add below entry in web.xml.
    <context-param>
   <param-name>log4jConfigLocation</param-name>
   <param-value>file:${DOMAIN_HOME}/configuration/log4j.xml</param-value>
 </context-param>
 <context-param>
   <param-name>log4jExposeWebAppRoot</param-name>
   <param-value>false</param-value>
 </context-param>
 <listener>
   <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>

4) Restart the server.

You are done with log4j configuration !!
