Query: Awful book. Save yourself some time and money.

I was very excited to hear about this book. Unfortnatly, after reviewing this book, I found many errors. I'm returning this book today. There are screen shots that are from previous versions of Jbuilder. In one section they ask you to use JDBC explorer but all of the screen shots are for SQL Explorer which doesn't ship with JB3 anymore. That's just to name a few. This book could easily be cut in half and still be considered a book on JB3. There are filler chapters on OO programming and concepts as well as chapters on Java programming. Save yourself some time and money. Read a good general purpose book on Java and then read the manuals that ship with JB3. You'll be much better off.
