----------------------------------------

Yes.  There is a solution.  It is overcomplicated and not intuitive.

> I am trying to filter my log4j.properties file in WEB-INF.  One line is troublesome.  The resulting line should be 
> log4j.appender.mine.File=${myProject.root}/WEB-INF/logs/mine.log
> where myProject is the value of the property project.artifactId.
> I try 
> log4j.appender.mine.File=${${project.artifactId}.root}/WEB-INF/logs/mine.log
> but no substitution is done.
> After much trial and error, I use
> log4j.appender.mine.File=!#!$${log4j.root}/WEB-INF/logs/mine.log

> <properties>
>   <log4j.root>{$project.artifactId}.root}</log4j.root>
