'm generally a fan of the books from O'Reilly Press, but the quality level seems to have slipped in recent years. This book on the Eclipse IDE is only somewhat useful. It's also a bit out of date now, though it's hard for publishers to keep up with the revision rate of some software.
This book isn't horrible, but neither is it particularly insightful. It doesn't really tell you anything you couldn't figure out if you spent enough time with Eclipse. It doesn't really go into the different ways of using Eclipse and why you might choose to set up projects in different ways.
If you're a complete neophyte with integrated development environments then it might be worthwhile, bu totherwise, look for a different book or just spend more time poking around.
This book is not, in my own view, a book probably written from a request by the editor. The job is done to show to the reader how to use the IDE to perform a Java development, even including some (now outdating) frameworks. This book seems to be here to fill a hole in the editor's catalog. On the other hand, Steve Holzner is a very decent writer. For such a book, I've seen much worse. Still, the purpose of this book isn't obvious, maybe except for those who need a book for anything ? ma note de lecture en français ici
