I want to have the log files stored in a another folder than standalone/log. So, I have updated the standalone.xml configuration file as below:

<server xmlns="urn:jboss:domain:1.2">

    <extensions>

      .

      .

    </extensions>

    <system-properties>

        <property name="log.root.dir" value="/tmp/logs"/>

    </system-properties>

   <profile>

        <periodic-rotating-file-handler name="FILE_DAILY" autoflush="true">

             <formatter>

                 <pattern-formatter pattern="%d %-5p [%c{1}] %m%n"/>

             </formatter>

             <file relative-to="log.root.dir" path="c3s_daily.log"/>

             <suffix value=".yyyy-MM-dd"/>

             <append value="true"/>

        </periodic-rotating-file-handler>  

.

.

When I am starting Jboss, the property log.root.dir it is not recognized. Do you know why? I would appreciate your help. Thank you.
