             Summary: Servlet Example of using different 
log4j2-{env:envValue}.xml
                 Key: LOG4J2-747
                 URL: https://issues.apache.org/jira/browse/LOG4J2-747
             Project: Log4j 2
          Issue Type: Bug
          Components: Configurators
    Affects Versions: 2.0-beta9
         Environment: Websphere 8.5 Windows 7 
            Reporter: A B


Based on my previous post / question on the log4j2 user list - Defining 
different log4j2.xml configurations based on environment - 
http://apache-logging.6191.n7.nabble.com/Defining-different-log4j2-xml-configurations-based-on-environment-tp40639p40662.html
 - I was attempting to create a  Servlet Example of using different 
log4j2-{env:envValue}.xml.  

This is what I did

Based on the answers in this thread "Defining different log4j2.xml 
configurations based on environment", from log4j user list I tried to test 
using a different config for different environments. 
This is what I have done.

•I defined a Windows env variable websphere_environment and set its value to 
"local"

•My web.xml context-param looks like below - My servlet version is 3.0

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/config/log4j2-${env:websphere_environment}.xml
    </param-value>
</context-param>

• My relevant servlet method looks like below

protected void doGet(HttpServletRequest request, HttpServletResponse response) 
throws
    ServletException, IOException {

    Logger logger = Logger.getLogger(ServletLog4j2Test.class.getName());
    logger.fatal("Loaded:);
    //    " + /WEB-INF/config/log4j2-${env:websphere_environment}.xml
}

• I do not have the lo4j2-local.xml defined in the WEB-INF/config ( it is 
defined as log4j-local.xml, not log4j2-local.xml and was expecting to get an 
error but it seems that the servlet is using a default configuration, because 
when I run the servlet, I get

"07/24/14 07:14:07:564:FATAL:WebContainer : 0:        :     
:com.test.log4j2.ServletLog4j2Test: Loaded:"

• How should my web-app and config files be set-up so that I can use different 
configs for different environments based on the environment?
