When independent business components must be executed simultaneously, the parallel processing of application business logic has a direct impact on the performance of the system; however, parallel processing at the application level historically has been challenging to implement. In the case of J2EE applications that rely on the services provided by the application server containers, implementing parallel and concurrent processing is an uphill battle. Over time, the Java messaging services (JMS) API has become a de facto solution for parallel business logic processing by utilizing the asynchronous messaging features offered by the API. Although JMS provides a solid foundation for developing J2EE applications that use asynchronous messaging, it does not automatically produce the desired end result. JMS poses the following challenges: JMS provides the pieces to solve the... (more)

Cover Story: A Practical Solution to Internationalization of a J2EE Web App

As the Internet crawls to even more remote corners of the globe, the internationalization of Web applications exposes a plethora of challenges. As a real-world example, if an airline starts reaching far more remote destinations across international frontiers, a Web application representing the airline's ecommerce will face numerous challenges in terms of internationalizing the ecommerce itself. These challenges result from many causes. For instance, one basic thing that differs from one country to another is the spoken language. Among countries where the same language is spoken, ... (more)

An Introduction to Maven - Part I

Maven is a promising application development lifecycle management framework coming from Apache's armory of open source tools. Maven was originally developed as a framework to manage and mitigate the complexities of building the Jakarta Turbine project and soon became a core entity of the Apache Software Foundation project. Without a uniform application development lifecycle management framework, different development teams would create their own build frameworks with varying flavors and complexity and this tendency would only proliferate as more and more new projects get develop...

An Introduction to Maven - Part II

In part one of this article we discussed the core competencies of Maven and how it fits into application development and build management. Now we'll delve into some of the practicalities in exercising Maven using a practical example that will walk you through some of the common tasks encountered in typical project development and how they can be done using Maven. Downloading & Installing Maven The latest version of Maven 2 can be downloaded at http://maven.apache.org/download.html, Maven's official site. When this article was written, Maven 2.0.6 was the latest version available. ... (more)

An Introduction to Maven - Part III

In the parts 1 and 2 of this article, we demonstrated how to download and install Maven 2, how to install the Maven 2 plugin for Eclipse, and how to go about setting up a project directory structure using Maven 2. We used a simple use case for displaying employee details on the Web given an employee ID, but deliberately made the design a bit complex by introducing design concepts such as XML binding, EJBs, and JCA connectors to illustrate a few of the many features offered by Maven. In this final installment of the article, we continue with the remaining modules in our example an... (more)
