log4j basic configuration

Question

Hi,

I used log4j to log some steps in my application. To be quick and dirty, I used:

org.apache.log4j.BasicConfigurator.configure();

This output my logs in the Eclipse console.

I want to know if and how to set the level threshold higher than DEBUG? In other word, I do not want to display DEBUG level message, just ERR, WARN, INFO.

Thank you.

EDIT: May I use this following?

import org.apache.log4j.Logger;
import org.apache.log4j.Level;
[...]
Logger logger = Logger.getLogger(this.class);
logger.setLevel(Level.INFO);

1) Find your appender, you sould have something like this in your log4j.xml configuration file.

    <appender name="DEBUG" class="org.apache.log4j.RollingFileAppender">
 <param name="File" value="C:/logs/rmDebug.log"/>
 <param name="Append" value="true"/>
 <param name="MaxFileSize" value="1500KB"/>
 <param name="MaxBackupIndex" value="2"/>
 <layout class="org.apache.log4j.PatternLayout">
  <param name="ConversionPattern" value="**FOOBAR** %d{dd.MM.yyyy HH:mm:ss} %c  %m%n"/>
 </layout>
 <filter class="org.apache.log4j.varia.LevelRangeFilter">
  <param name="LevelMin" value="DEBUG" />
  <param name="LevelMax" value="FATAL" />
 </filter>
</appender>

You see levelMin and LevelMax value ? levelMin is where you begin to log, and levelMax, where you stop to log. ( with this specific appender ). You can have several appender.

Then for assign this appender to a class or package. You can do something like that :

    <category name="com.foobar.automation.doremiResourceManager" additivity="true">
 <appender-ref ref="DEBUG"/>
</category>

I think the simplest way would be:

    Logger.getRootLogger().setLevel(Level.INFO);
