Query: This book rocks!

Great examples, quick and too the point explanations make this a very good book to hit the ground running learning JSP.If you are a professional developer like me, and you don't want to deal with a lot of lengthly overwritten explanations and books written by twenty different people (i.e., Wrox publications) this is the book to get. Goodwill knows his stuff when it comes to Java and he is able to convey it to the reader in an understandable way.Also, check out "JavaServer Pages Application Development" by Ben Forta another very good JSP book.
