Not able to log in different files: Log4j

Question

abcI am trying to log messages in two different log files using log4j API. Below is my log4j.xml

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

<appender class="org.apache.log4j.RollingFileAppender" name="OnlineFile">
    <param value="UTF-8" name="Encoding"/>
    <param value="D://abc//logs//Online.log" name="File"/>
    <param value="500" name="MaxBackupIndex"/>
    <param value="10000KB" name="MaxFileSize"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param value="%d{ISO8601} : %-6.6c : %-5p : %X{APP} : %-7X{USER} : %-2X{MODULE} : %-20X{REFDATA}  : %m%n" name="ConversionPattern"/>
    </layout>
</appender>
<appender class="org.apache.log4j.RollingFileAppender" name="ABCFile">
    <param value="UTF-8" name="Encoding"/>
    <param value="D://abc//logs//Sample.log" name="File"/>
    <param value="500" name="MaxBackupIndex"/>
    <param value="10000KB" name="MaxFileSize"/>
    <layout class="org.apache.log4j.PatternLayout">
        <param value="%d{ISO8601} : %-6.6c : %-5p : %X{APP} : %-7X{USER} : %-2X{MODULE} : %-20X{REFDATA}  : %m%n" name="ConversionPattern"/>
    </layout>
</appender>
<logger name="Online">
    <level value="debug"/>
</logger>
 <logger name="ABC">
    <level value="INFO"/>
    <appender-ref ref="ABCFile"/>
</logger>
<root>
    <level value="debug"/>
    <appender-ref ref="OnlineFile"/> 
</root>

It is somehow only logging in Online.log.Even fetching the correct using in the following manner fails to log in Sample.log

Logger.getLogger("ABCFile").info("My message");

Not able to figure out what's wrong! Any help?

Answer 1

"ABCFile" is the name of your appender, your log is named "ABC". try:

Logger.getLogger("ABC").info("My message");

Answer 2

check getLogger() API. You should use logger name not File Appender name. Change code like below.

Logger.getLogger("ABC").info("My message");
