The loggers, if their names contain dots (like yours es.indra) form a hierarchy based \
on these dots. If in code you you fetch a named logger (i.e. "es.indra.something") \
there will be a logger instance in the repository but no appenders attached (because \
it is not configured in the xml file). Log statements issued on this logger climb up \
the hierarchy. The logger "es.indra" is found, and its appender served. If there is \
no additivity attribute (or ="true" which is the default) the climbing goes on until \
it reaches the root logger. All Appenders of all Loggers found on this way are \
served. If a Logger is found which has the additivity flag="false" the climbing up \
the hierarchy stops. So, log statements issued on the logger "es.indra.segurcaixa" \
end up in the configured logger "es.indra" and not reach the root logger, but \
statements issued to a logger named "com.xy" would reach the root logger. Heri

es.indra.segurcaixa.expedientevirtual.event.cataloger

Hi Heri:
Reviewing this XML , I saw the root logger has the same appender-ref
ref="CATALOGER_FILE_APPENDER" .
So this should have the same impact?
Below I copied the all XML which I reviewing.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

    <appender name="CATALOGER_FILE_APPENDER"
class="org.apache.log4j.RollingFileAppender">
        <param name="File"
value="C:/apps/segurcaixa/expvirtual/workspace/scev-fs/logs/scev-cataloger.log"
/>
        <param name="Append" value="true" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d %-5p - %m%n"/>
        </layout>
    </appender>

    <appender name="CONSOLE_APPENDER"
class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.Out"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d %-5p - %m%n"/>
        </layout>
    </appender>

    <category name="es.indra" additivity="false">
        <level value="DEBUG"/>
        <appender-ref ref="CATALOGER_FILE_APPENDER"/>
    </category>


    <category name="es.indra.segurcaixa.expedientevirtual.event.cataloger"
additivity="false">
        <priority value="WARN"/>
        <appender-ref ref="CATALOGER_FILE_APPENDER"/>
    </category>

    <root>
        <level value="WARN" />
        <appender-ref ref="CATALOGER_FILE_APPENDER"/>
    </root>

</log4j:configuration>
