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 the protocol for their interaction. First, the need for a framework like the InfoBus for current Java architectures is identified. Then the InfoBus, its components and the InfoBus API are briefly described. This is followed by an example that illustrates how to build an application using the b... (more)

IMHO: Blueprinting Java

Last year Sun came out with a new set of design guidelines for building enterprise applications using enterprise Java APIs. These APIs are available as a set of documents called the J2EE Blueprints. They include architectural design guidelines for developing enterprise applications using the Java 2, Enterprise Edition APIs. The Silver Bullet The primary benefit of the Blueprints is that after five years and several releases of Java platform products and APIs, there's finally a comprehensive story of how all these technologies offered by Java can plug and play together in enterpr...

Phasing in SOA and Web Services

Over the last couple of years, the industry has rallied around SOA and its main realization platform - Web services. While many of the clients I meet are still wary about the adoption of new technology, integration dilemmas posed by the variety of software and hardware platforms has led them to buy into the promise of improving on business agility through SOA. 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)

The Digital Consumer: Big-Data-Enabled-Cloud's Final Destination

I used to be a regular presenter at SYS-CON's tech.conferences. After a hiatus of a few years, I thought of presenting at the Cloud Expo conference in New York. I was wondering which track to participate in. You see, although, Infosys Limited,  the company I work for, has a very large Cloud practice, I belong to a space which is more of a consumer of what Cloud offers. To me Cloud and Big Data are the plumbing for the house that we build for clients. I have helped incubate one of the strategic focus areas within Infosys - digital transformation, which is powered by Cloud. The a... (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)
