Subject [jira] [Commented] (LOG4J2-747) Servlet Example of using different log4j2-{env:envValue}.xml
Date Fri, 15 Aug 2014 11:40:18 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-747?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098478#comment-14098478

A B commented on LOG4J2-747:
----------------------------

Remko / Matt,

Also, this probably isn't the correct place for asking this, so let me know, if I should ask
a separate question / bug report.  I haven't been able to send the the mailing list for some
time, evn though I have registered and used that address before, when I sent this question
to that list multiple times, it did not show up there.

Anyways,   I did not find any information on how to initialise log4j2 ( preferably with similar
file info as I tried here ) in an EJB3 application / project.   Previously, I would use the
@startup bean & @PostConstruct along with  {{PropertyConfigurator.configure(log4jProp);}}
with log4j, but haven't found a way to do this in log4j2.  Could you point me to any documentation
that outlines it for EJB3, log4j2 combination?

Thanks

> 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.
 
> 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"
> * I specify the config location as log4j2-\{env:envValue\}.xml. My web.xml context-param
looks like below - servlet version is 3.0.
> {code}
> <context-param>
>     <param-name>log4jConfigLocation</param-name>
>     <param-value>/WEB-INF/config/log4j2-${env:websphere_environment}.xml
>     </param-value>
> </context-param>
> {code}
> My relevant servlet method looks like below
> {code}
> protected void doGet(HttpServletRequest request, HttpServletResponse response) throws
>     ServletException, IOException {
>     Logger logger = Logger.getLogger(ServletLog4j2Test.class.getName());
>     logger.fatal("Loaded:);
>     //    " + /WEB-INF/config/log4j2-${env:websphere_environment}.xml
> }
> {code}
> 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
> {code}
> "07/24/14 07:14:07:564:FATAL:WebContainer : 0:        :     :com.test.log4j2.ServletLog4j2Test:
Loaded:"
> {code}
> 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?
