> log4j2.xml not found by default in WEB-INF folder
> -------------------------------------------------
>
> Key: LOG4J2-1024
> URL: https://issues.apache.org/jira/browse/LOG4J2-1024
> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators
> Affects Versions: 2.3
> Environment: Tested on
> Windows 7 + Eclipse Juno + tomcat 7.0.62
> and
> CentOS 6.2 + tomcat 7.0.61
> Reporter: Patrick Zimmermann
> Priority: Minor
>
> I have a web application, included log4j-api-2.3, log4j-core-2.3 and
> log4j-web-2.3 and placed a log4j2.xml file in the WEB-INF folder.
> On application startup I receive the following message:
> ERROR StatusLogger No Log4j context configuration provided. This is very
> unusual.
> ERROR StatusLogger No log4j2 configuration file found. Using default
> configuration: logging only errors to the console.
> When I add
> <context-param>
> <param-name>log4jConfiguration</param-name>
> <param-value>/WEB-INF/log4j2.xml</param-value>
> </context-param>
> to my web.xml the error notification disappears.
> According to the documentation at
> http://logging.apache.org/log4j/2.x/manual/webapp.html Log4J2 should search a
> file starting with log4j2 in the WEB-INF folder if no context-param is
> specified.
> It seems, this does not happen.
