Answer 1

Faced more issues while making this work. Here are the details:

1. To download and add apache-log4j-extras-1.1.jar in the classpath, didn't notice this at first.
2. The RollingFileAppender should be org.apache.log4j.rolling.RollingFileAppender instead of org.apache.log4j.RollingFileAppender. This can give the error: log4j:ERROR No output stream or file set for the appender named [file].
3. We had to upgrade the log4j library from log4j-1.2.14.jar to log4j-1.2.16.jar.

Below is the appender configuration which worked for me:

<appender name="file" class="org.apache.log4j.rolling.RollingFileAppender">
        <param name="threshold" value="debug" />
        <rollingPolicy name="file"
            class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="FileNamePattern" value="logs/MyLog-%d{yyyy-MM-dd-HH-mm}.log.gz" />
            <!-- The below param will keep the live update file in a different location-->
            <!-- param name="ActiveFileName" value="current/MyLog.log" /-->
        </rollingPolicy>

        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%5p %d{ISO8601} [%t][%x] %c - %m%n" />
        </layout>
</appender>
