My last blog showed how Spring is soaring past EJB. Research by BZ Media and others shows that Apache Tomcat is the leading open source application server with a 64% market penetration. The dominance of Spring and Tomcat is well-known. What people may not know as well is that thousands of organizations are [...]

One of the central themes behind Spring 2.5 is comprehensive annotation-based configuration. We've been talking and blogging a lot about @Autowired, about Spring MVC's @RequestMapping and also about the new support for annotated tests written with JUnit4 or TestNG. @Autowired is certainly the central one of Spring 2.5's annotations, being available for use in service [...]

I am glad to report (along side Adrian) that after 3 milestones and 2 release candidates, Spring Dynamic Modules (formerly known as Spring OSGi) 1.0 has been released.
A lot of features have been improved or added since my previous post (about 1.0 M1); I'll talk more about them in future entries (there is also the [...]

Well, it took a lot longer than we initially anticipated, but I'm really pleased to say that the Spring Dynamic Modules project reached its 1.0 milestone today. When I first posted on this topic back in September of 2006 ("Spring OSGi support gaining momentum") the initial specification was just an attachment to an issue against [...]

Job listings are a good indicator of the true adoption of technologies. They indicate whether or not companies are spending money, making it possible to distinguish substance from hype; they indicate the importance for developers of gaining and growing the relevant skills (an important element of technology perpetuation); and they provide a good guide to [...]

Spring's dependency injection (DI) mechanism allows configuring beans defined in application context. What if you want to extend the same idea to non-beans? Spring's support for domain object DI utilizes AspectJ weaving to extend DI to any object, even if it is created by, say, a web or an ORM framework. This enables creating domain [...]

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 [...]

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 [...]

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 [...]

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 [...]
