  • 0

I am using log4j for my application – there I need to see all log messages, so I defined

# General configuration
log4j.rootLogger = ALL, ConsoleAppender

# Appender configuration
log4j.appender.ConsoleAppender = org.apache.log4j.ConsoleAppender
log4j.appender.ConsoleAppender.layout = org.apache.log4j.PatternLayout
log4j.appender.ConsoleAppender.layout.ConversionPattern = %5p (%c) %m%n

But, after I started using Apache’s HTTPClient library (which is awesome btw), my console got clouded up by its logging – everything was logged and I am not able to see the log output from my own application any more.

So how can I tell the HTTPClient library that it should only log WARN messages, while my own application still logs on ALL levels?

I create my application logger using

Logger logger = Logger.getLogger(MyClass.class);
PropertyConfigurator.configure("log4j.properties");

    It’s quite simple. Just add the below line.

    log4j.logger.org.apache.commons.httpclient=WARN

    Similarly, you can configure levels for any package com.foo or class com.foo.Bar by appending it to the prefix log4j.logger as follows:

    log4j.logger.com.foo=MYLEVEL
log4j.logger.com.foo.Bar=DEBUG
