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 enterprise-level applications. Using the Blueprints as guidelines also helps architects and developers make choices between alternative technologies and products, based on the constraints of their business and operating environments. The J2EE Blueprints address enterprise application development usi... (more)

Anatomy of a Java Application Server

Several folks in the computing industry think of 1999 as having been the "Year of the Application Server." But while the term application server itself may be a fairly recent addition to the software computing vocabulary, the application server market has already become one of the fastest-growing markets in n-tier computing. Business analysts estimate its value as being likely to reach the multibillion-dollar level in 2001. In today's distributed computing environment, the term application server is associated with state-of-the-art technology. Perhaps that's why several vendors ... (more)

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)

XML Development

Have you ever been called an XML developer or XML programmer? While processing XML in programs has become a common task for computer programmers, XML is used only in the context of some other programming language environment, such as Java, C++, and Web programming languages. We've all become accustomed to the presence of XML in the very guts of our applications over the last couple of years. Most IDEs in the market today offer tools for manipulating XML for the purpose of creating and deploying software components. Eventually the data formats expressed by XML have to be processed...

Managing the Stack in Java Platform

As the complexity of enterprise applications grows with the increased offerings in the Java platform, the management of the different building blocks that constitute the application also becomes very complex. The challenge in managing applications in the enterprise is posed from many fronts. Organizationally, the corporation has to decide whether they manage all the IT services for the applications in-house, or leverage the benefits of outsourcing to meet the needs of their environment. Typically the hosting of applications and the management of the lowest tier of the stack - the... (more)
