Online stores are the new, next-generation, "revolutionize the world as we see it today" way of doing business. In the context of business transactions, online stores use the global Internet to facilitate the purchase and sale of goods and services. The ability to support online sales is an essential component of the new e-business paradigm for Internet-based businesses today. Putting together an enterprise-level application for an Internet store involves design and integration of various technologies that play specific roles in a distributed computing environment. A distributed topology is a prerequisite for building such Internet applications since the Internet is inherently distributed in nature. Due to the plethora of technology alternatives available in the computing arena today, designing architectures for an enterprise application involves choosing between t... (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)

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)

Java for the Enterprise

Hello and welcome to Java's Karma - The Cosmic Cup. The word Karma originates from Hinduism and means fate or destiny; or the cosmic principle according to which each person is rewarded or punished in one incarnation according to that person's deeds in a previous incarnation. In this column, we will examine Java's Karma - Java in its rapid incarnations; new and upcoming Java technologies that are going to determine Java's role in the computing world. Indeed, Java has already moved beyond the realm of a programming language and holds the promise of uniting enterprise computing under... (more)

Focus: The Java Platform

Welcome back to the Cosmic Cup. I hope you are enjoying our voyage through the Java universe. Last month we examined the APIs that are formally defined under the scope of the Java Platform for the Enterprise. We're going to change the course of our journey a bit. This month we will look at the APIs that define the Java Platform itself. What is the Java Platform? Before getting deeper into the discussion, I would like to comment on the terms "Java Platform" and the "Java Enterprise." The Java Platform is defined as "a new operating environment for delivering and running highly in... (more)
