I am working on a command line application using log4j (1.7.10).
In log4j.xml, the application has 4 applications configured for different types of logs, as shown below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
debug="true">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<appender name="regularAppender" class="org.apache.log4j.RollingFileAppender">
<param name="maxBackupIndex" value="10" />
<param name="file" value="./target/logs/develop.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601}|%p|%t|%m%n" />
</layout>
</appender>
<appender name="errorsAppender" class="org.apache.log4j.RollingFileAppender">
<param name="maxBackupIndex" value="10" />
<param name="file" value="./target/logs/errors.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601}|%p|%t|%m%n" />
</layout>
</appender>
<appender name="secure-appender" class="com.company.slogger.SecureAppender">
<param name="file" value="./target/logs/secure.log" />
<param name="pattern" value="%d{ISO8601}|%p|%t|%m%n" />
<param name="verifyPattern" value="TIMESTAMP|LEVEL|THREAD|MESSAGE" />
<param name="numberLogLines" value="10000" />
<param name="timerLogMilliseconds" value="300000" />
<param name="triggeringTime" value="3600000" />
<param name="encoding" value="UTF-8" />
<param name="logFileNamePolicyName" value="SEQUENTIAL_DATE_FILENAME" />
</appender>-->
<logger name="std">
<level value="INFO" />
<appender-ref ref="regularAppender" />
</logger>
<logger name="SecureLogger" additivity="false">
<level value="INFO" />
<appender-ref ref="secure-appender" />
</logger>
<root>
<level value="INFO" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
Logging works fine. The problem is that when the application starts, about 30 lines of log4j configuration messages are displayed on the screen, as shown below:
log4j:WARN Continuable parsing error 61 and column 23
log4j:WARN The content of element type "log4j:configuration" must match "(renderer*,appender*,(category|logger)*,root?,categoryFactory?)".
log4j: Threshold ="null".
log4j: Retreiving an instance of org.apache.log4j.Logger.
log4j: Setting [std] additivity to [true].
log4j: Level value for std is [INFO].

log4j: Retreiving an instance of org.apache.log4j.Logger.
....
This is a command line application, so the user is not very pleased to see all these messages at startup.
How to configure log4j to write these messages to a log file, not to the screen.
Thank!
