RE: Log4J - Downsides?

["Steven Caswell" <stevencaswell@yahoo.com>]

One obvious disadvantage of the jdk1.4 log facility is that it is only
available with jdk1.4, whereas log4j is available on any recent jdk.

I've been using log4j for a while and I love it. One thing I have done
is to adopt the Apache Jakarta common-logging package. This package
defines a logging interface that an application can program to without
having to commit to a particular logging implementation. By coding to
the commons-logging interface, you can plug in your logging package of
choice, as long as its architecture translates reasonably to the
interface. Currently the commons-logging package contains implementation
translations to log4j and the jdk1.4 logging package.

Check out commons-logging at
http://jakarta.apache.org/commons/logging.html
