Arjen Poutsma, core developer of the Spring Framework's Web services subproject, has posted an excellent tutorial on how to approach Web services development in contract-first style, i.e. starting with the XML Schema/WSDL contract instead of Java or C# code.SOA Development Survival Guide

It strikes me that this is just another example of interface-first design - TDD applies this at the Java interface level; here, it's at the webservice level. We've been through the same thing with IDL and CORBA, RMI and J2EE - think hard about the granularity, clarity, domain relevance, performance flexibility of your interfaces - there are different design pressures at play at the remote interface level compared to the java interface level.
Well, test-driven development doesn't necessarily dictate interface-first design, but it's certainly a practice worth thinking about. For me it works really well in the world of curly braces, especially in combination with tools like EasyMock. It's good to see that approaches like these are finally starting to appear in the web services world as well!
Thin client paradigm characterized by web applications is a kludge that needs to be repudiated. Old compromises are no longer needed and it's time to move the presentation tier to where it belongs.
In this presentation filmed during QCon 2007, Jeff Sutherland, the creator of Scrum, talks about his visit at Google to do an analysis of Google's first implementation of Scrum.
In this article, Bryon Jacob and Chris Berry introduce AtomServer, their implementation of a full-fledged Atom Store based on Apache Abdera, which is now available as open source.
It is easy to think that virtualization applies only to servers. In reality the recent resurgence of the concept is also being applied to networking, storage, and application infrastructure.
In this article, Stefan Tilkov explains some of the most common anti-patterns found in applications that claim to follow a "RESTful" design and suggests ways to avoid them.
In this article, Adrien Louis and Marc Dutoo discuss the differences and relative merits of using orchestration vs. routing in a typical ESB setup, and discuss various implementation options.
Wayne Lund discusses batch processing, Spring Batch objectives and features, scenarios for usage, Spring Batch architecture, scaling, example code, failures and retrying, and the future roadmap.
