دانلود کتاب JSF 1.2 Components

I was offered a chance to review a copy of the JSF 1.2 Components book by Ian Hlavats and published by Packt Publishing. The book covers a number of different JSF frameworks including 1.2 Reference Implementation (RI), Facelets, Apache Tomahawk and Trinidad, ICEfaces, and RichFaces. My overall impression of the book is a 2/5 stars.

Why?

When you are trying to teach someone to use a new technology, the source code must work, and the effort to get it to work should be minimal. This is not the case with the accompanying source code. There are a number of errors in the code that a modern IDE and technical reviewer should catch. This applies to the code examples in the book. The configuration and requirements to use Eclipse for the projects are a shame for anyone wanting to use another IDE. The projects should have been set up to use Apache Maven to make them IDE neutral.

I also do not like partial code examples. I believe that code should stand on its own. If you are going to provide code snippets, then the code provided must be complete and functional. This was not the case.

The first chapter covers the very basics of JSF RI. This is a very shallow introduction to the RI.

Chapter 2 Covers Facelets. It is one of the best explanations I have seen on Facelets and is very easy to understand and follow. This chapter makes the book worth buying if you are interested in Facelets technology.

Chapter 3 on Apache Tomahawk does a good job of representing the framework. There are a lot of great components in Tomahawk (75+) which play nicely with other JSF frameworks.

Chapter 4 covers Apache Trinidad (A.K.A. Oracle ADF Faces). It does a reasonable job of demonstrating the framework, and has inspired me to look a little further into it. I found it very easy to use, and found myself trying other components which were not covered in the book. I do have some issues around the code examples and implementation which I will cover in the detailed section below.

Chapter 5 covers ICEfaces. It is a really good example of some of the things that ICEfaces can do, and the components are very eye catching. My chief complaint with ICEfaces compared with some of the other frameworks is that it is really messy to set up tables, and sorting.

The book fumbles at the finish line. The chapters of the book on Seam (Chapter 6) and Richfaces (Chapter 7) are totally blown. The authors decision to do Seam before RichFaces and not separate the code base was a bad decision. The chapters themselves are not too bad, but the code would not run. Since Chapter 7 depends on Chapter 6 code, the result is a quagmire.

I created a Maven POM for Chapter 6 and set to work on the dependency issues. I had done the same thing for the previous chapters by converting them into Maven projects. This time the project failed to run and there were a number of issues. In fact, too many issues to overcome. I resolved to use the code and instructions provided by the author and the code failed to run as well. I am convinced that the Seam and database portions of the code examples are not configured correctly. After spending a week trying to make it work in both Maven and Eclipse, I quit. It should not require me spending hours trying to make it work. The code is supposed to make it easy for me to get a handle on these technologies and not troubleshoot it.
I can not validate that the code works as the author has written it in the book since the code does not work in the provided examples.

Summary

My overall impression of the book is a 2/5 stars. I really liked some portions of the book, like chapter 2 on facelets, and chapters 3 & 4 on Apache MyFaces component frameworks.

Two chapters (6 & 7) appear to provide some really relevant data, but the sample code provided with the book on which this chapter depends falls short. As a result, I can not really assess Chapter 6. Chapter 7 depends on the successful function of Chapter 6 for the most part, and is really short changed by the failure of the Seam and database connectivity. Some of the sample code for Chapter 6 works so that you can get a glimpse into the power of RichFaces.

I noted that I made a number of the examples into Apache Maven projects. I would offer them out to the public, but the code has no licensing noted in the source, and was really meant for my consumption. If you are the author, publisher, or an interested party, I will provide it to you on request.

I would really like it if Packt would consider requiring all of their sample code be provided in Maven projects. This would make the them IDE neutral, and ensure the quality of the projects by providing exact dependencies.
