Trouble with log4j configuration

Question

I have been trying to change the logging from console to both console as well as file. Looking at the large documentation on log4j I was able to add the appender as shown in the code below. However I don't seem to be getting logs in the specified file.

Any ideas what might be wrong? Here is my log4j.xml (already located at src/)

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

    <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
        <param name="Threshold" value="DEBUG"/>
        <param name="Target" value="System.out"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
        </layout>
    </appender>
    <appender name="FILE" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="false" />
        <param name="file" value="/data/MFlogs/log.log"/>
        <param name="immediateFlush" value="true"/>
        <param name="threshold" value="debug"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
        </layout>
    </appender>


    <root>
        <priority value="DEBUG" />
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </root>

</log4j:configuration>

Why you are using xml file, you can do the same thing with properties file. in xml if there is a whitespace, it create problem. try to copy the content then delete it from xml , save the blank file again paste it and save. – kavi temre May 06 '15 at 04:10
everything looks fine in your xml, sometime eclipse/IDE didn't parse xml file, try to restart eclipse/IDE. – kavi temre May 06 '15 at 04:11

Try adding full path to path location or add ${catalina.home}/logs/myApp.log to it.

Read this question, it tells how to use relative path. It is easy if you use properties file instead of xml file.

Okay I'm confused. Are you asking me to use absolute or relative? What I am using is the absolute path. `value="/data/MFlogs/log.log"/>` I'll try with relative. – Ashwin May 06 '15 at 04:18
If it is absolute path, check permissions of the location or some other issue. – Maleen Abewardana May 06 '15 at 04:20
All three have the correct owner. This is really puzzling. – Ashwin May 06 '15 at 04:23
