Good overview but renders badly on kindle (including Apps)
This book covers very high level usage and configuration of log4j. I wish it went into more depth on best practices or setup across a project bigger then on Class.
The configuration section is helpful.
The rendering of this book on a kindle or kindle app is very poor and hard to read. If the author can, this book should be cleaned up and submitted back to amazon as an update.
