Java Developer's Journal Exclusive: 2006 "JDJ Editors' Choice" Awards

The editors of SYS-CON Media's Java Developer's Journal are in a unique position when it comes to Java development. All are active coders in their "day jobs," and they have the good fortune in getting a heads-up on many of the latest and greatest software releases. They were asked to nominate three products from the last 12 months that they felt had not only made a major impact on their own development, but also on the Java community as a whole. The following is a list of each editor's selections and the reason why they chose that product. Joe Winchester Desktop Java Editor SwingLabs SwingLabs is an open source laboratory for exploring new ways to make Swing applications easier to write, with improved performance and greater visual appeal. It is an umbrella project for various open source initiatives sponsored by Sun Microsystems and is part of the java.net community... (more)

What's New in Eclipse?

Since Eclipse's first release in 2001, it has become a popular environment for Java development. In the period between March 10 and May 11, 2005, users downloaded over 17,000 copies of one of the production SDK releases and over 3,500 copies of one of the stable (milestone) SDK builds on average every day. A vibrant eco-system of developers, plug-in providers, authors, and bloggers has grown up around it. Eclipse has also gained the backing of the key Java vendors including BEA, Borland, IBM, SAP, and Sybase. Developers like Eclipse because it provides a great platform for building Java applications, and companies like it because it unifies their software tools under one open source umbrella.  In late June of this year, the latest release of the Eclipse Platform, version 3.1, will be available for download from eclipse.org. In this article, I'll highlight some of t... (more)

i-Technology 2008 Predictions: Where's RIAs, AJAX, SOA and Virtualization Headed in 2008?

2007 was undoubtedly the year of Social Networking, but what of 2008? Will '08 be the year of "Unified Communications" or the year when CMS comes to stand for "Community Management System" - or even "Collaboration Management System"? Or will it be the year of a giga-merger, to beat the mere mega-mergers of 2007? As usual at the end of each year, SYS-CON has been informally polling its globe-girdling network of software developers, industry executives, commentators, investors, writers, and editors. As always, the range and depth of their answers is fascinating, throwing light not just on where the industry is going but also how it's going to get there, why, because of who, within what kind of time-scale.

Adopting OSGi in Java Application Frameworks: A Case Study

Migration of software systems to the OSGi platform is gaining momentum with wide acceptance of the OSGi technology as the dynamic module system for Java. This transition is of special interest when it comes to popular Java application frameworks, which attract a growing number of Java developers around the world. Although the technical merits of the OSGi platform are broadly recognized, the migration of existing application frameworks is slow due to significant redesign and re-implementation efforts involved. We present an alternative lightweight approach - an adaptation of existing Java application framework for component based OSGi environment. Adaptation, as opposed to migration, eliminates the necessity of modularizing or redesigning the existing framework. This is particularly important when existing software platform and the associated programming model is mat... (more)

Exclusive Q&A with Mike Milinkovich, Eclipse Foundation

"We continue to struggle a bit with what developers think “Eclipse” means. They have heard of it, but they believe that we are entirely focused on Java tools when in fact we are doing so much more," says Mike Milinkovich, Executive Director of the Eclipse Foundation, in this exclusive Q&A with Jeremy Geelan. "Our goals at Eclipse are to create an industrial-strength open source development platform that spans extensible tools, frameworks and runtimes," adds Milinkovich - pictured here during a previous Webcast on SYS-CON.TV from our Times Square studio. Eclipse Developer's Journal: May 20th marked your 4th anniversary as the Executive Director of the Eclipse Foundation. What have been the biggest changes in the Eclipse ecosystem in that time? Mike Milinkovich: I believe the biggest change is the breadth of the projects that are happening at Eclipse today, and the eco... (more)

"Eclipse 3.0 is a Great Leap Forward," Says JDJ's Dudney

To view our full selection of recent Eclipse stories click here Today the Eclipse Foundation announced general availability of the royalty-free 3.0 release of Eclipse - described by the Ottowa-based foundation as a platform "for tools integration, software modeling, and testing that has been broadly adopted by commercial vendors, academic institutions, and open technology developers." Bill Dudney, JDJ's Eclipse editor, commented, "I am very excited about the promise of Eclipse 3.0. With each new milestone release the platform has become richer in its feature set, better performing and generally more productive to use." "From the enhanced Java tools to the improved integration with Ant and other open source projects," Dudney continues, "Eclipse 3.0 is a great leap forward. In addition to enhancements to the Java developer tool box the whole plugin architecture has bee... (more)

Building SOA with Tuscany SCA

Many articles have already been written about service-oriented architecture (SOA) and Service Component Architecture (SCA), for example, see references [1] and [2]. In this article we'll focus on a freely available, open source implementation of the Service Component Architecture that provides a simple way to implement SOA solutions. This SCA implementation is being developed in the Apache Tuscany Incubator project. The project started in 2006 and is being used by many who are looking for a simple SOA infrastructure. The recent Tuscany SCA version 1.0, which was released in September 2007, supports the Service Component Architecture specifications 1.0. In addition to implementing the SCA specifications, Tuscany is also a nursery for new ideas. Some of these ideas will find their way into the specifications and some will be regarded as extensions available in Apache ... (more)

Universal Middleware: What's Happening With OSGi and Why You Should Care

The Open Services Gateway Initiative (OSGi) Alliance is working to realize the vision of a "universal middleware" that will address issues such as application packaging, versioning, deployment, publication, and discovery. In this article we'll examine the need for the kind of container model provided by the OSGi, outline the capabilities it would provide, and discuss its relationship to complementary technologies such as SOA, SCA, and Spring. Enterprise software is often composed of large amounts of complex interdependent logic that makes it hard to adapt readily to changes in requirements from the business. You can enable this kind of agility by following a Service Oriented Architecture (SOA) pattern that refactors a system into application modules grouped by business functions that expose their public functionality as services (interfaces). For example, a customer... (more)

An Exclusive Interview With Mike Milinkovich Of Eclipse Foundation

Mike, thanks for agreeing to talk to JDJ and bringing us all up to date with Eclipse since our last interview with you. The best way is probably just to fire off questions and allow you to answer without getting in your way! JDJ: Overall, how's the independence from IBM going? Since most of Eclipse's committers were IBM employees when you first went independent, how is building a community around Eclipse that is not so IBM focused going? MM: It's going really well. Frankly, it's going much better and much faster than I had originally anticipated when I started the job. In many ways we have accomplished in the past year what I had expected would take two years or more. First, the importance of adding companies such as BEA, Borland, and Computer Associates to our board cannot be overstated. Each of these companies competes fiercely with IBM in the marketplace. Each is ... (more)

JavaOne 2008: SOA, SCA, REST and Comet Discussed

DeCare Systems Ireland Blog Even though 'Service' comes first in SCA (Service Component Architecture), SCA is a distributed component model. It's about designing components (and composites) rather than designing services. It doesn't feel like it was designed to build a SOA. It feels like its main goal was to define a distributed component model. And as we all know, the distributed component models failed in the past. I think SCA will too. For the second day of JavaOne my schedule contained technical sessions and BoFs about mostly SOA, SCA, REST and Comet. SCA I attended two more sessions about SCA: - Open-Source SOA with SCA and Apache Tuscany - Open Standards for SOA and Java technology The second one was a panel session. The host was MC David Chappell of Chappell and Associates and the panellists were David Chappell of Oracle, Mike Edwards of IBM, Steve Jones of Capgem... (more)
