This book covers a lot of the technologies of Server-side Java application development. However, it doesn't cover them in depth to make this book the reference in any of these technologies. Another drawback, is the work and difficulty involved in setting up the software products necessary to replicate the environment used in the book, which is not covered at all in it.Buy this book only if you're trying to get a single one-shop coverage of these topics. Don't buy it if you're looking for comprehensive coverage of Server-side Java technology (actually, you'll need several different books for that).
