Print error in console without date and time using log4j

Question

Will it be possible to just print the error message in console using log4j without including date, time and severity details.

Log 4j.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
  <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
  <param name="threshold" value="ERROR" />
        <layout class="org.apache.log4j.PatternLayout">
              <param name="ConversionPattern" value="%d{yyyyMMdd HH:mm:ss,SSS} - %p | %m%n" />
        </layout>        
  </appender>

<logger name="package" >
    <level value="ERROR" />
    <appender-ref ref="CONSOLE" />
</logger>

  <root>
        <priority value="ERROR" />
        <appender-ref ref="CONSOLE" />
  </root>
</log4j:configuration>                                                         

Answer 1

You can check various ways of tweaking the output of log4j in Pattern Layout . You could try using the following pattern layout to print only the message that has to be logged to console

   <param name="ConversionPattern" value="%m%n" />
