I just got back from JavaOne in San Francisco this weekend. My humble opinions on the conference are presented elsewhere in this issue of JDJ. As expected, one of the main themes of JavaOne this year was the J2EE platform and related technologies. Over the last two years, since Sun announced the three editions of the Java Platform, J2EE has come a long way. The products offered by third-party vendors are mature - and a large part of the mundane development activities are abstracted from the programmer. With the Java Connector Architecture (JCA) specification around the corner, integration with Enterprise Information Sources (EIS) also becomes much clearer and more manageable. Openness Has Its Advantages J2EE is definitely more open than any of the other enterprise software platforms available in the industry. However, this openness also means that Sun, as the owner ...

The Proof Is in the Concept

In a large project, designing for performance often turns out to be a chicken or egg situation. In a J2EE project, this is even more evident. Typically when business and functional requirements are handed down to the technical team, the first step is to map the functional subsystems into software components, and then to hand out the design of those components to respective team leads for design and implementation. This is part of the responsibilities of the project architect. At this stage in development, the onus is on the architect to make decisions on identifying potential b... (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. In last mo... (more)

Welcome To J2EE

As Alan Williamson, JDJ's editor-in-chief, mentioned earlier in this issue, JDJ 2.0 is a total redesign of JDJ; our intention is to reflect the developments in the Java platform as closely as we can. Some of you may be familiar with my role in JDJ - I wrote a column, E-Java, and was one of the editors. I'm honored to wear the hat of the J2EE editor for JDJ 2.0. Alan and I have worked together in the past and I'm sure that the synergy between us will take JDJ 2.0 to new heights - all focused on your needs. So, without further ado, Welcome to J2EE. This section is dedicated to the ... (more)

An Introduction to EJBs With Lots of Code

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 ... (more)
