This was actually the first book on Enterprise JavaBeans that came into the market. Enterprise JavaBeans was released in June and made its debut at JavaOne this year. This is a pretty good book for developers who like to see a lot of code. The examples in the book are used to develop a fairly complex application and the code isn't meant for novices. Tom Valesky presents many examples. I like the fact that the book takes an example and builds its complexity in successive chapters. There's good coverage of distributed architectures and transactions. The author has also dedicated a chapter to provide some excellent guidelines for building distributed systems. For readers just starting out in distributed applications, the author provides the appropriate background. This book isn't for everyone, though. Readers already familiar with distributed systems and transactions m... (more)

Now Playing: XML, In A Crucial Role In Application Server Suites

During the last couple of years there have been several developments in the application server environment. Nineteen ninety-nine truly was the "Year of the Application Server."

The term application server almost always refers to Java application servers (Microsoft's MTS and COM+ notwithstanding), i.e., application servers based on the J2EE platform. The main developments in the Java application server market have been: Stabilization of the J2EE platform Acceptance of the EJB object model Matur... (more)

Phasing in SOA and Web Services

The ubiquitous nature of Web services is something that even business owners appreciate, as they have been burned before by the disparity in the technologies that their applications have been based on. Many of the clients ... (more)

Other Java APIs And Products

Let's take a minute to recap the discussion we've had so far in The Cosmic Cup. The Java platform is the software platform for the computing environment defined by Java. The Java platform APIs define the application programming interface for the Java platform, which consists of categories of APIs that address different segments of computing and related industries. However, several APIs defined under the scope of Java APIs don't fall under any of the formal categories defined under the Java platform, namely Base Platform, Commerce, Security, Media, Enterprise and Server.

Living Inside the Box

One of my recent clients had an entire suite of applications that was built on an in-house messaging framework. Several years ago, when not many Java frameworks existed in the market and J2EE was still a few years away, this would have been considered a good thing; today, any new development on a proprietary framework takes the client further away from fully leveraging the facilities offered by J2EE. Although there is definitely a strong push to move to a J2EE enterprise type of environment, migrating legacy systems to J2EE is a formidable undertaking. While this problem can be ... (more)
