Warning using rollingPolicy in log4j.xml configuration file

[Antonio Angelino]

Hello,

I am a new user of log4j package and I have a problem using rollingPolicy,
this is the warning message:

*log4j:WARN Unrecognized element rollingPolicy*


JAR included in buid path:

- log4j-1.2.15.jar
- apache-log4j-extras-1.0.jar

- commons-logging-1.1.1.jar
- commons-logging-adapters-1.1.1.jar
- commons-logging-api-1.1.1.jar
- and others...

log4j.xml file:

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";>
    <appender name="stdout" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
                value="%d [%t] %5p %c{1}:%L - %m%n" />
        </layout>
    </appender>
    <appender name="ROLL" class="org.apache.log4j.RollingFileAppender">
        <param name="file" value="log/example.log"/>
        <param name="append" value="true" />
        <param name="encoding" value="UTF-8" />
        <rollingPolicy
class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="fileNamePattern" value="log/example.%d.log.gz" />
        </rollingPolicy>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d [%t] %5p (%F:%L) -
%m%n" />
        </layout>
    </appender>
    <logger name="com.mansydis">
        <level value="debug"/>
    </logger>
    <root>
        <level value="info" />
        <appender-ref ref="stdout" />
        <appender-ref ref="ROLL" />
    </root>
</log4j:configuration>



I followed log4j documentation but I don't understand why rollingPolicy is
not accepted by log4j.

What is wrong in my configuration file?


Thank you in advance for your help,

Antonio.
