[jira] [Commented] (LOG4J2-804) XInclude does not respect classpath

["Oscar Korz (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17398902#comment-17398902 ] 

Oscar Korz commented on LOG4J2-804:
-----------------------------------

It seems like composite configurations require a system property to be set. Using system properties is much more tedious for development than logback's <include/> mechanism which can allow the default configuration file to just work regardless of what class was executed or how it was executed.

> This issue is related to the one resolved by https://issues.apache.org/jira/browse/LOG4J2-341
> The <xi:include> element does not respect entries provided on the classpath. 
> Specific use case: I have a log4j2.xml configuration I wish to share across several applications providing a common base of appenders and plugins, these are bundled into a myorg-logging.jar to be used in downstream projects that wish to provide configuration for their loggers. In the myorg-logging log4j2.xml I wish to optionally include a file from the classpath called myorg-logging.xml
> == log4j2.xml ==
> <Loggers>
>   <logger name="root" level="env:rootLogLevel:-WARN"/>
>   <logger name="my.org" level="env:myOrgLogLevel:-INFO"/>
>   <xi:include href="myorg-logging.xml">
>     <xi:fallback/>
>   </xi:include>
> </Loggers>
> I also noticed once a Loggers or Appenders section has been declared in xml, it can not be appended to with a second Loggers or Appenders section (which would be nice for a top level additive xi:include scenario instead of limiting to an included file just for loggers, a file just for appenders, etc)
