3.0 out of 5 stars Incomplete look at Portal development, June 22, 2004

By	Thomas Paul (Plainview, NY USA) - See all my reviews (REAL NAME)

There seems to be a new breed of technical cookbook book that involves throwing a lot of different technologies into a stew and hoping that what comes out is flavorful. Unfortunately, the result is more often than not, a less than tasty meal. This book is a prime example. Although it claims to be a guide to portal development using Java, it is mainly a bare bones discussion of lots of open source technologies without tying them together.

The book starts with an introduction to the Java Portlet API. This should be the heart of the book but in 35 pages we get a glance at some aspects of portals and some tables that give us a little on what but virtually nothing on how or why. Thinking that this was simply a quick introduction I wasn't too let down but then the book moves on to short chapters on Lucene, Apache James, Apache OJB, and Jakarta Slide. The book talks about security, planning, JavaScript, deployment, web services, etc. The one thing that is lacking is a feel for how this should all fit together within the Portlet API.

Taking each chapter by itself, some of them are good while others cover little more than the surface of each topic. Overall, the book fails to be a guide to developing a portal using Java. It should be considered as a series of articles dealing with different aspects of portal development but without any real connection.

1.0 out of 5 stars Just like a Poorly Architeted Portal - A Framework without Much Substance , August 5, 2005

By	Dr. Karl N.-Y. Zhang (Houston, Texas) - See all my reviews

Enterprise portal based on Portlet is very flexible for rapid development. A good practice is to plug-in quickly a variety of portlets as placeholders to compose a mock-up portal as the baseline for further detailed discussion with stakeholders. Of course, all the parties involved know that the mock-up presented is still a mock-up and they expect there is a production release at the end.

This book is also a mockup, though we readers did not know this until we paid this book as the final deliverable.

This book has two parts. The first part, Open Source Portals, contains 6 chapters. Chapter 1, The Java Portlet API (JSR 168), mainly lists lengthy attribute names and descriptions for CSS Style Definitions and for User Information Attributes, without much explanation. Much better material may be found online just a google away. Many pages are given to the code of a sample portlet. The explanation is as much as the comments made by poor programmer, almost none. Why do we readers have to pay in order to have the pleasure to read poorly commented coding? The sample is built upon Apache Lucene API, though it has not been introduced at this stage at all.

The remaining 5 chapters in the first part introduce several subjects that may be used to support a portal development, researching with Lucene, messaging with Apache James (for mail), object to relational mapping with Apache OJB, content management with Jakarta's Slide, portal security. The authors take these pieces of the components of their portal framework. A problem with this book is that the authors keep introduce a large amount of terminologies and software components without much insight. For instance, they never bother to explain why they use Apache OJB in their portal framework. Isn't Hibernate also a popular O-R mapping tool? I wish the authors explained to us other alternatives and at least some hints of why they choose certain open source tools instead of the others in portal development. This is particular important for using open source tools since there are often many alternatives.

The second part is titled How to Build a Portal. Again, you will discover many placeholders without much substance. For instance, under Design Pattern Consideration in Your Portal, nine standard design patterns are presented, several lines of description for each. The authors just do not bother to explain why they consider these 9 patterns are important for portal development and other are not, or they merely provides a partial list to demonstrate design patterns are still important to portal development as it is for any other development. I will give you another example here. Chapter is devoted to Effective Client-Side Development Using JavaScript. The coverage here is just common for any web development. I do not understand why the authors make this subject an entire chapter, in particular since this book covers a large amount of subjects in a moderate 400 pages, and in particular some fundamental subjects are still missing, such as the coverage of portal servers/containers.

I am not kidding. Open source portal/containers are not covered much in this book for Professional Portal development. Open source portal servers are briefly mentioned in the introductory part in about one page, each in several lines. Apache Jakarta Pluto is covered in a bonus chapter on the book's companion Web site. Apache Jakarta Jetspeed is mentioned in 7 linesJ. Liferay Enterprise Portal is introduced in 15 lines. This books give more coverage on EXo Portal. is introduced in 8 lines and it is introduced briefly again at Chapter 9, when a moderate Portlet is demonstrated.

According to the publisher, "An outstanding team of authors provides a complete tutorial and reference guide to Java Portlet API, Lucene, James, and Slide, taking you step-by-step through constructing and deploying portal applications." The book fails to deliver this promise.

4.0 out of 5 stars Respectable portal development book, January 17, 2005

By	KBaker (MI) - See all my reviews

I have been developing software for three years and found this book helpful in writing portlet code for a BEA 8.x portal program i have been on for two months now. This book was also helpful for some javascripting that was needed for client side form validation i needed to implement
