Hi,
I was looking for a logging bundle, found apache commons already
available as a bundle. So I just used
Log log = LogFactory.getLog(My.class);
log.info(...);
and hoped it would "just work". And so it does, I get output on the
equinox console.
How can I configure that output, "appenders", etc? Would I just look at
the apache manual pages? Anything special when this is used in an OSGi
environment?
Cheers,
Felix

Hello Felix,
you need to configure Logger. Default logger writes all output to
console. To configure a logger, you can either specify system property
"org.apache.commons.logging.Log" with name of your Logger class (i.e.
-Dorg.apache.commons.logging.Log=com.my.Logger), or attach a fragment to
org.apache.commons.logging plugin with commons-logging.properties file,
as specified in Apache Commons Logging configuration.
Your configured Logger must implement org.apache.commons.logging.Log
interface [1]. It can do whatever you want, e.g. create a Status object
from log message and write it to eclipse log.
If you want to use apache commons logging with log4j, you need to create
a fragment for org.apache.commons.logging.Log plugin with configuration,
which depends on log4j. Another fragment (this time for log4j plugin)
will contain log4j.properties configuration. (Maybe this is too complex,
and somebody will suggest something simpler, but it should work).
