My .gwt.xml properties:

           <!-- Add gwt-log support, default level `DEBUG` -->
        <inherits name="com.allen_sauer.gwt.log.gwt-log-DEBUG"/>

        <set-property name="log_RemoteLogger" value="ENABLED"/>
        <!-- Turn off the divLogger -->
        <set-property name="log_DivLogger" value="DISABLED"/>

I am using gwt 2.0.3 and gwt-log 3.0.1

Log4j properties:

    <appender name="R" class="org.apache.log4j.RollingFileAppender">
    <!-- DEV -->

            <param name="MaxBackupIndex" value="2"/>
            <layout class="org.apache.log4j.PatternLayout">

            </layout>
    </appender>

    <logger name="gwt-log">

        <appender-ref ref="R"/>
    </logger>

Thanks in advance!
