Discover JBoss Seam: the Unified Framework for Simpler, More Powerful Web Development

 

JBoss Seam integrates EJB 3.0 and JSF components under a unified framework that simplifies and accelerates Java EE web development. Now, JBoss Seam’s project leader and technology evangelist take you inside this powerful new technology, showing exactly how to put it to work. 

 

Michael Yuan and Thomas Heute show how JBoss Seam enables you to create web applications that would have been difficult or impossible with previous Java frameworks. Through hands-on examples and a complete case study application, you’ll learn how to leverage JBoss Seam’s breakthrough state management capabilities; integrate business processes and rules; use AJAX with Seam; and deploy your application into production, one step at a time. Coverage includes

 

How JBoss Seam builds on—and goes beyond—the Java EE platform

• Using the “Stateful Framework”: conversations, workspaces, concurrent conversations, and transactions

• Integrating the web and data components: validation, clickable data tables, and bookmarkable web pages

• Creating AJAX and custom UI components, enabling AJAX for existing JSF components, and JavaScript integration via Seam Remoting

• Managing business processes, defining stateful pageflows, and implementing rule-based security

• Testing and optimizing JBoss Seam applications

• Deploying in diverse environments: with Tomcat, with production databases, in clusters, without EJB 3, and more

5.0 out of 5 stars concise code examples, May 22, 2007

This review is from: JBoss® Seam: Simplicity and Power Beyond Java™ EE (Paperback)

Yuan and Heute offer the Java programmer a very tempting route away from using the standard Java Enterprise Edition. As they point out, EE version 5 is an uncomfortable mixture of EJBs and JSF. The EJBs exist on the server side and encapsulate business logic. While the JSF is used, also on the server side, as a model-view-controller framework for Web work. In general, separating the MVC from the business logic is correct. But if you have to code EJBs and JSF together, then things get awkward. Code gets verbose and hard to structure.

The book's alternative is Seam, which is meant to be a filler between EJBs and JSF. One nice aspect is that Seam is inherently stateful. For a Web user session, this is vital, and it's nice from the text to see state built into Seam, without you having to shoehorn it in.

Perhaps the most persuasive parts of the book are the code examples. Granted, the authors wrote these to be as concise and elegant as possible. But if you accept that most authors of computer books do this, then you can quickly appreciate the contrast between the code here and comparable code in texts on EJBs and JSF. The latter code examples are much longer and more intricate. The brevity of code writing that Seam affords you can greatly help in two ways. Quicker to write. And quicker to debug.

Having said this, I am undecided about one aspect of the text. Involving what is called "dependency bijection". It is meant as a lightweight way for POJOs to interact with each other. As opposed to using framework interfaces or abstract classes. But the extensive use of interfaces (and abstract classes) has led to the successful development of extensible packages like Eclipse. (And I'm sure readers can cite other examples.) Is it the case that interface implementations do have limitations, perhaps in the context of Web servers and business logic?

5.0 out of 5 stars EXCELLENT INTRODUCTION TO SEAM!, July 19, 2007

I needed to develop a project and fast. I purchased this book because I needed to get Seam up and running quickly. I found it very clearly written: with helpful examples and source code. It also provides a introduction to AJAX and has a few chapter on how to integrate AJAX with JSF and Seam. Very interesting! I recommend this book 100 percent!

This review is from: JBoss® Seam: Simplicity and Power Beyond Java™ EE (Paperback)

Its a great book.. It difficult to learn Seam without this book.
It may be slightly dated, with Seam 2.0 coming out recently.
But per the author, there are not significant changes in the code
ie mainly config changes.
(eg they recommend JPA with tomcat instead of embedded server option
with tomcat)

Seam(and specifically seam-gen) still has some significant bugs/issues
to iron out(but workaround exists).
