log4j w/apache

[cpanon <cp...@yahoo.com>]

Hello
Newbie on ussing log4j and now that I have a simplistic log4j configuration file I am seeing ALL of the apache all from org.apache.commons.digester.Digester or org.apache.commons.digester.Digester.sax.  How can I stop that but still keep a simple or reconfigure my log4j.properties?  tia.

Strictly speaking, it doesn't matter what level (e.g. WARN) you choose
if you've going to send everything to the bit bucket.

This is only required is you really don't want to see /anything/ from
Apache classes. I would recommend just setting the Apache-classes logger
to WARN like this:

log4j.logger.org.apache=WARN

...and leave it at that. You might actually want to see warnings from
these classes, but certainly TRACE-level detail from them is is way too
much to see.

This is described here:

http://www.mail-archive.com/log4j-user@logging.apache.org/msg10697.html

If you truly want them to go nowhere you can do this:

log4j.logger.org.apache.commons.digester.Digester=WARN, nowhere
log4j.logger.org.apache.commons.digester.Digester.sax=WARN, nowhere
log4j.appender.nowhere=org.apache.log4j.varia.NullAppender
log4j.additivity.nowhere=false

The real trick is that you have to send those messages to a logger
that won't pass them up (i.e. additivity=false).

Using the documentation you should be able to take it from here.
