Note: This post has been edited to reflect Spring's move to Pivotal. A more recent blog on Spring Training and Certification is here.

Since I joined SpringSource six months ago as the Director of Training, I have been hearing one consistent request. Based on the growing demand for Spring skills, developers and consultants worldwide are seeking quantifiable ways to demonstrate their Spring expertise. Likewise, the hiring managers behind that demand are asking for a certification program to help identify and hire technologists who have an immediately useful, baseline knowledge of Spring.

Much like the way the Spring project teams respond to the needs of the open source community, we have responded and are pleased to announce the SpringSource Certification Program. This program kicks off this month, January 2008, with the Spring Framework Professional…

Quite a day for news as we complete our first annual Spring eXchange in London. First, the news that Sun Microsystems acquired MySQL, and then the long anticipated acquisition of BEA Systems by Oracle. Before commenting any further, I want to congratulate all of our friends at MySQL, especially Mårten Mickos, and all of our friends at BEA. The trend of consolidation in this industry is increasing.

As an open source company, we are thrilled to see MySQL rewarded for their effort. We have seen how hard Mårten and his colleagues have worked to build their software, community and a strong…

Last Friday was Tony (C.A.R.) Hoare's birthday. Who is C. A. R. Hoare? If you're a programmer, you're probably familiar with Quicksort--an elegant and surprisingly simple sorting algorithm that is blazingly fast in most cases. If you studied computer science, you've almost certainly implemented Quicksort in numerous languages, and will recognize the animation on this page. Hoare invented Quicksort in 1960, and it's now the most widely used sorting algorithm.

Among other contributions, Hoare also invented the Communicating Sequential Processes (CSP) language used to specify the interactions of…

Spring 2.5.1 is the first bug fix and enhancement release in the Spring 2.5 series. It closes a couple of gaps found in Spring 2.5 final and introduces various new features in the context of Java 6 and Java EE 5 support:

• Java-5-specific Model interface for use with MVC handler methods
• @ModelAttribute's default attribute names are consistently derived from the *declared* parameter/return type
• Support for last-modified handling in @RequestMapping handler methods (through the WebRequest interface)
• SpringBeanAutowiringSupport class for self-autowiring classes within a web app (e.g. JAX-WS endpoints)
• EJB3-compliant SpringBeanAutowiringInterceptor for processing Spring's @Autowired in EJB3 SBs/MDBs
• Remoting support for the HTTP server that is included in Sun’s JDK 1.6 (covering HTTP invoker, Hessian and Burlap)
• "jms:listener-container" tag supports a concurrency range (e.g. "3-5"), for specifying a minimum number of consumers
• Tiles2 support works on JDK 1.4 as well
• Any many further enhancements in the details…

Spring 2.0.8 is a bug fix release in the Spring 2.0 series, addressing all issues reported since 2.0.7 and backporting various minor refinements from Spring 2.5.1. This is the last planned 2.0.x release. We recommend upgrading to Spring 2.5.1 where lots of new features are waiting for you to try them...

At The Spring Experience, I hosted a session various aspects. One of them was the Hibernate synchronization aspect that I described last week. Another was an aspect capable of capturing first failures and system state, sometimes called First-Failure Data Capture (FFDC). I hosted this session to show off some aspects that are very useful, but that people might not have come across in practice yet. I often hear people asking about aspects other than logging, tracing, transaction management and security. The Hibernate synchronization aspect and the FFDC aspect are nice examples I think.

Introduction

Let's…

Mixing code in one and the same transaction that uses an Object-Relational Mapper with code that doesn't, can cause issues with data not being available in the underlying database when it should be. Since this is a situation I come across once every now and then, I figured it would be helpful for all if I write down my solution to this problem.

In short: what I will present in the remainder of this post is an aspect that triggers the underlying persistence mechanism (JPA, Hibernate, TopLink) to send any dirty data to the database.

I presented this aspect by the way during one of my sessions at The Spring Experience last December and this post also has the source code for those of you…

It has been quite a year for Spring.NET. We have gone through two milestone and two release candidates before the GA release in December. The first chunks of code for the 1.1 release were made way back in late 2004 by Aleks Seovic who started work on the ASP.NET framework. In short, it has been a long time in the making. Being the end of year, a natural time for reflection both past and present, I'd like to say thanks to the other members of the project and the Spring.NET community for all their contributions and support. I'm looking forward to a great 2008!

The feature set of Spring.NET 1.1 is quite broad. An IoC container for Dependency Injection, AOP, ASP.NET framework, declarative transaction management and more. However, the biggest bang for the buck you can get to improve the structure and testability of your code is to add Dependency Injection and AOP into your proverbial developer tool chest. Dependency Injection is the more foundational…

Sometimes important changes sneak up. Such changes aren't driven by marketing campaigns, but by many individual decisions; there's no fanfare; by the time they're observed, they have surprising momentum. I mentioned one such development in my opening keynote at the recent Spring Experience conference: the steady rise of Tomcat.

Recently we've begun running polls on SpringFramework.org, and some of the results are interesting. The question Which application server(s) do you use? produced the following results: BEA WebLogic (various versions) and JBoss AS shared first place among Java EE app…
