Kurzbeschreibung
This is a hands-on practical guide to a large variety of topics and use cases. This book tries to use real-world examples when possible, but is not afraid to come up with a contrived pretext if it makes explaining the problem simpler. Unlike a lot of other books, this one does not try to maintain a continuous theme from chapter to chapter, such as demonstrating solutions on the same fictional application; doing so would be almost impossible given the wide variety of recipes presented here. Instead, this book concentrates on focused problems users are likely to encounter and shows clear solutions in a step-by-step manner. This book tries to teach by example and is not afraid to show a lot of code because, after all, it is for coders. This book is for current users of the Apache Wicket framework; it is not an introduction to Wicket that will bore you with tons of theory. You are expected to have built or maintained a simple Wicket application in the past and to be looking to learn new and better ways of using Wicket. If you are ready to take your Wicket skills to the next level this book is for you.

Format:Taschenbuch
ich kann nicht sagen das das Buch schlecht ist, aber von diesem Autor hätte ich deutlich mehr erwartet. Immerhin ist er einer der großen Namen hinter dem Framework. Es bleibt bei Beispielen auf einem Niveau wenig über den Hilfetext oder diversen anderen Büchern. Keine Interna, keine besonderen Tipps und Kniffe, keine wirkliche tiefe. Von einem Kochbuch erwarte ich mir. Nämlich Tipps und Tricks jenseits der Grundlagen und Hinweise zu komplexen Aufgabenstellungen und kritischen Elementen wie Unterstützung mehrerer Sitzungen oder mehrerer Browser tabs. Nichts davon findet sich hier.
Die drei Sterne gibt es weil das Buch ein solides Grundlagenwerk ist, dass für Anfänger übersichtlich darstellt wie Wicket Applikationen mittlerer Komplexität aufgebaut werden. Bücher wie Wicket in Action leisten etwa dasselbe, sind aber didaktisch teilweise besser aufgebaut.

Das Buch finde ich wirklich schlecht:
Es besteht hauptsächlich aus Code-Ausschnitten, die Praktisch nicht erklärt sind, und allgemeinen oft wenig Sinn haben.
Manche Code-Ausschnitte sind nicht komplett, und wirklich fast ohne Kommentare, das macht manchmal, sogar für erfahrene Entwickler das Verständnis schwierig.
Viele Beispiele basieren auf Anti-Paterns, wie überschreiben von onRender() um eine Model-Implementierung zu umgehen. Es kann sein, dass es alternative Wege zeigt, oder erklärt zum Beispiel das Page-Rendering, aber der Autor konnte darauf hinweisen.
Ich vermute, dass der Autor, etwas Java-Code aus Tutorials zusammengefügt hat und das ganze mit ein paar Kommentaren versehen hat ....

Really useful & well thought-out
13. Mai 2011
Format:Taschenbuch
This isn't a casual introduction to Wicket - it's much, much more useful than that. This book is aimed squarely at someone who has picked up the basics of the framework and now has some real-world problems to solve. If you've ever asked questions on the mailing lists for Wicket, you'll know that the author (Igor) is exceptionally active and helpful there. His experience helping people through various common issues and use cases for web development on the mailing lists really shines through in the selection of examples and "recipes" in the book.
The Apache Wicket Cookbook covers a really useful and diverse set of functionality, from preventing multiple form submits and security issues to chart visualization and making your site look pretty. I really like the way that each recipe is presented in sections: "Getting ready", which contains skeleton code before the addition of the functionality; "How to do it...", which has the meat; "How it works...", which explains things concisely but thoroughly; and "There's more..." with often invaluable extra coverage of how to extend or override the functionality in the best way. It's easy to digest, superbly thought out and gives you a good framework to grasp all the information quickly.
This is an excellent book - it's jam-packed with useful content and avoids the verbose and pompous language so popular with many technical authors. It works both as a dip-in-and-out reference and as an in-depth guide to some parts of the Wicket framework that are difficult to uncover for yourself. I was a developer on the core Wicket team until a couple of years ago, so hopefully I know what I'm talking about: Quite simply, if you create applications with Wicket, you should have a copy of this book on your desk.

The book the community was waiting for!!
1. Juli 2011
Format:Taschenbuch
Igor Vaynberg is not new to the Wicket landscape, being actually a core committer of the framework and a name that every Wicket developer well know.
The book, following the Packt well established "Cookbook" format, is not a comprehensive learning guide to the Apache Wicket framework; It's a cookbook, a list of 'recipes' aimed to solve specific, real problems. and It does just that, darn well.
The book is aimed at an audience of developers already skilled (at least a little bit) in the Wicket framework and in look for solutions to common day-to-day problems.
This book is, in this regard, exactly what the community was waiting for.
Igor is very clear, specific and never prosaic; The given examples are down-to-earth, real world examples of what you would expect to find and bang your head against when you develop your average Apache Wicket application.
Each chapter of the book is devoted to a particular aspect of the framework: Validating and converting user input, forms, i18n, data tables and views, tabs and borders, Ajax, charts, security and integration with middlewares (Spring, JBoss Weld, JPA).
It has not to be read sequentially; there are no long and complex projects to build and follow between each chapter; It's organization is perfect for being used as a reference; each chapter contains specific examples of "problems" to solve, a workable solution to the problem and a thorough explanation of "how" the solution works.
Every chapter has its clues, its 'tips' and hints that make this book a memorable reading for every Wicket developer; even the most basic examples on how to work out validation of a field give precious hints on how validation works 'under the hoods', or when it's better to access the value of a field during validation using the getConvertedInput() method instead of the model value (guess why ? read the book and you'll know..)
Decorating components, creating grids and sorting/filtering data, blocking until Ajax requests complete, adding charts with Open Flash Charts library; this book is full of incredible useful information that every Wicket developer will be able to leverage to improve its productivity and knowledge of this fantastic framework.

Great resource for users of Apache Wicket
30. Mai 2011
Format:Taschenbuch
The Wicket Cookbook is a great resource for Wicket users to solve common problems in web applications. All recipes are explained in great detail and can be followed easily. The book contains very instructive and easy to follow code samples.
This isn't an entry-level book though. You should have done some Wicket coding or read an introductory book first. Good Java knowledge and OO skills will make it easier to master this book.
Without doubt this cookbook will improve your coding skills, whether you will be continuing to use Wicket or not.
As one of the reviewers I was allowed to scrutinize the book's contents before its publication. It's a pleasure to follow Igor's coding skills. Calling myself a seasoned Wicket user, I still learned a lot of new Wicket tricks.
