One of the salient aspects of the Java language is the control it gives to developers for dynamically generating and reusing code. This allows the language to offer Java programmers the ability to write code in which the actual behavior is determined at runtime. Of the eleven buzzwords used to define Java, this article is going to focus on the dynamic nature of the Java programming language.

J2EE Has Come a Long Way

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, i... (more)

eXtreme J2EE

When I first started programming, it was with a small company. Life was simple. I understood all the requirements, and knew all the aspects of the application and how to pull everything together. If I was working with a team of programmers, the projects were small enough that the team knew each other's code thoroughly. Mi code es su code. Software engineering was easy to follow; code and design walkthroughs involved everyone, and, given time, any person could pretty much handle the whole project on his or her own. I moved on in my career and, in the last decade, as technology star... (more)

Tagging the Servlet: Part 1

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 ... (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...
