Although I've been following EJB 2.0 very closely, it was only recently that I walked into a project that was the perfect venue for its new features, such as the much enhanced container-managed persistence and local interfaces. And Enterprise JavaBeans, written by Richard Monson-Haefel, fit the bill as a reference and learning guide. This is a "must-have" book if you want an introduction to EJBs, are migrating from EJB 1.1 to 2.0, or want to build a new application using EJBs. The author provides a brief introduction to distributed objects and component models in the first chapter; however, if you're unfamiliar with these concepts or with database design, this is not the right book for you. Enterprise JavaBeans talks in detail about the obvious - Enterprise JavaBeans - and stays focused on the subject. I was very impressed with the organization of the book, which ma... (more)

Cloud Expo New York: Six Not-So-Blind Men and the Cloud Elephant

I'm glad I stayed on after the breakout sessions to attend the CEO Power Panel at 7 pm at the 12th International Cloud Expo, in New York. It was quite informative and entertaining. As with everything else, the best way to get a view of a new technology area is by asking for independent opinions. The old adage of the six blind men and the elephant comes to mind. Coincidentally, there were six "blind men" on the panel, including our very engaging host, Jeremy Geelan (@jg21). And there were views that converged in a common theme: "Cloud Connects". Jeremy, as always, got the ball roll... (more)

Take a Ride on the InfoBus

Components transcend the programming language and support a very high degree of reuse. They greatly simplify the construction of large and complicated software architectures. One of the main reasons why Java promises such a bright future for the computing world is because of its inherent support for component architectures. Some examples of Java's component support are JavaBeansª, Java Foundation Classes (JFC), JavaBeans Activation Framework (JAF) and the InfoBus. This article introduces the InfoBus, a specification for interconnecting JavaBeans by defining the interfaces and th... (more)

Focus: The Java Scripts

The world of software programming is replete with alternative tools for writing code that can be used to provide the same solutions to the same problems. The range of programming aids available, and their disparate approaches, make ubiquity and platform neutrality a myth. Nowadays, someone who says that the Z80 assembly language is also a programming language will be shot down with a barrage of e-mail arrows fired by technical gurus. I think the only absolutely platform-independent, language-neutral, ubiquitous truth is that everything ultimately translates into a sequence of zer... (more)

Java in the Middle Tier

This month the Java platform segues into the new millennium. These are very exciting times; 1999 was a crucial year in the acceptance of Java in the enterprise as one of the key drivers of e-business. It's ironic that applets ­ the components of Java that helped propel it into the mainstream of Internet applications ­ currently occupy a backseat in the vehicle that propels Java into the 21st century. During the year gone by, the focus was on server-side Java, as predicted last year by several industry pundits ­ more precisely, on Java in the middle tiers of distributed computing.... (more)
