Packt Publishing is looking for potential authors who are fanatical about Liferay. No previous writing experience is necessary, just as enthusiasm for the subject and an ability to put their expertise into words.

Why is this an interesting area?

Liferay is becoming increasingly popular, developing features to compare with their commercial rivals, and finding increased usage in professional channels. However, with its ever increasing usage and constant development comes a greater need for clear information about getting the most from its applications.

Packt aims to publish books that will make Liferay applications accessible.

What topics do we want to cover?

Some of the topics that we are interested in are:

• Security
• System Administration
• Multimedia
• Ecommerce
• Project Implementation and Cookbooks for developers
• And more! If you think there's an area which is not mentioned here but has a strong potential, please do let us know.

Who are we looking for?

We are looking for authors who have an expert understanding of Liferay as well as an ability to put their knowledge into words. Although no previous authoring experience is necessary, experience writing tutorials, blogs or giving presentations on the subject would be an advantage. If you think you have a killer book idea on Liferay and fancy writing it, we are looking for you. Even if you don’t have a book idea but are simply interested in authoring a book in this domain, we are keen to talk to you!

I'm interested! What's the next step?

Fantastic! Just email  This e-mail address is being protected from spambots. You need JavaScript enabled to view it with a small note about your experience in this domain, any writing experience you may have, and your book idea if you have one.

The editorial team at Packt is keen to hear from you!

James Gosling has announced that it's time to move on and he has resigned from Oracle.

In his blog he says:

"Yes, indeed, the rumors are true: I resigned from Oracle a week ago (April 2nd). I apologize to everyone in St Petersburg who came to TechDays on Thursday expecting to hear from me. I really hated not being there. As to why I left, it's difficult to answer. The hardest part is no longer being with all the great people I've had the privilege to work with over the years. I don't know what I'm going to do next, other than take some time off before I start job hunting."

On behalf of the Develop In Java community I'd like to thank James for all the work he's put into making Java what it is today.  Certainly, without James, this site would not be here.  Thank you James, and good luck for the future.

Review: Apache MyFaces Trinidad 1.2 – A Practical Guide By David Thomas

Apache MyFaces Trinidad 1.2 by David Thomas introduces the Trinidad framework and shows how it can be used in combination with the Seam Framework to provide a “comprehensive and effective technology for the development of powerful rich-client web applications”.

The book is comprised of 12 chapters. The first 4 chapters primarily provide useful background information whereas the remaining 8 chapters provide lots of source code examples showing how to use Trinidad with Seam.

In the first few chapters, the author introduces Trinidad and explains why it could be used for development of Rich Internet Applications. He describes several reasons for choosing Trinidad such as the wide range of components (“well over 100”), the framework's interoperability and its maturity.

The author also introduces Seam early on in the book, but there is very little discussion about how to configure and get started with Seam. I think that some prior knowledge of Seam would be useful before reading this book.

After discussing Seam, the author continues to introduce Facelets and its templating facilities. Facelets is a JSF view technology that now a standard technology with JSF 2. In the book however, the author concentrates on JSF 1.x. As with the Seam discussions, I would have liked a deeper discussion on Facelets, but as this is not the major subject of the book I can understand why this is not included.

Moving on, the author begins to discuss Trindad in further detail by discussing the most commonly used tags and attributes for the different components and how Trinidad allows Pages to be partially rendered. Partial Page Rendering (PPR) is Trinidad’s AJAX technology that allows only sections of pages to be rendered based upon events such as button clicks within a web page.

The main detailed content (from a code point of view) begins in Chapter 5 where the groundwork for developing Trinidad / Seam applications begins. This chapter details how Seam applications can be built using the SeamGen tool and then imported into Eclipse. The author shows how to modify a standard SeamGen application to use Trinidad instead of RichFaces – RedHat’s competing JSF component framework.

The remainder of the book provides in depth code coverage on how to use different Trinidad components to build web application. The author describes the Trinidad dialog framework, how to build panels, and forms and how to use many different basic Trinidad components, such as text fields, number fields, trees and tables.

Finally, the author provides details on using Trinidad to generate charts and graphs, wizards and popup dialogs – features that are not available with all JSF component libraries.

This book is a good introduction to Apache MyFaces Trinidad 1.2. Packt Publishing describe the book as being written for “Java Developers who are beginners at JSF and experiences web developers who are looking for an introduction into the world of open source JSF technology”. I would agree with this sentiment, but would also recommend prospective readers have at least a basic knowledge of Facelets and Seam before enjoying the book.
