Although this doesn't demonstrate network logging, it is easy to accomplish this in conjunc-
tion with a logging implementation like
Log4J
or
JUL
which allow you to provide configur-
able logging.
Log4J
is described in the next recipe.

The SLF4J website contains a
Getting Started manual
that discusses the various classpath
options. There is also the
Maven artifacts
for the various options.
