Spring Batch 1.0.0.m4 Released

Spring Batch 1.0.0.m4 is available today via the s3 Milestone repository (browse at http://s3browse.com/explore/maven.springframework.org/milestone/org/springframework/batch).  See the Spring Batch downloads page for more information (http://static.springframework.org/spring-batch).

 

We have re-jigged the release schedule to squeeze in an additional milestone, to which Ben and Lucas are dedicated, so 1.0.0.m5 will be out in the next 10-14 days. Then we just have time for an rc1, with some contingency for rc2 if necessary, before the expected March 20 final release.

Spring Batch Recent Changes and Upcoming m4 Release

We’ve been working really hard on Spring Batch getting ready for the Spring Portfolio 2.5 release train, and I thought it would be a good time to update everyone on what is happening. In this article I’m going to expand a bit on the domain modelling, and our decision to raise the profile of some of the core domain objects, and increase their responsibilities. I will also give a few tastes of what is coming in the next couple of releases leading up to 1.0, so people have a chance to comment if they want to.

Some Decisions are Easy – Like SpringSource Acquiring Covalent

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 running Spring on Tomcat as their middleware infrastructure. Those organizations want one company to turn to for the products and services they need to be successful.

Today we announced our acquisition of Covalent Technologies. Not only does Covalent bring Apache leadership, but our combined company now has significant leadership on Apache Tomcat and HTTP. Two weeks ago, Sun paid $1bn for the “M” in LAMP. Now that Covalent’s outstanding Apache expertise and services are part of SpringSource, we are strong leaders in the “A”. We have always been about technology leadership, so we're very excited about what we can do together with Covalent. Over the last few years, Covalent has earned a great reputation in the marketplace with its support for Apache projects, including Tomcat and Apache HTTP. Its hundreds of support customers include more than half of the Fortune 500, and household names like Pfizer, Johnson & Johnson, British Telecom (BT), NASA, Intel, Royal Bank of Scotland and Bear Stearns. Our announcement today begins a new phase in the history of our company, and–I believe—the rapidly changing application platform market.

Spring 2.5's Comprehensive Annotation Support

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 components, web components, unit tests - even domain objects when using Spring’s @Configurable with AspectJ weaving. Spring MVC’s @RequestMapping is equally flexible, supporting many variants of handler method signatures.

Spring Dynamic Modules 1.0 is here

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 reference documentation that explains the library at length) so I’ll just name a few:

- consistency

We want to provide a powerful, simple and consistent programming model. That’s why Spring Dynamic Modules builds on top of Spring and uses its proven concepts, reliability and ubiquity.

Spring Dynamic Modules reaches 1.0!

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 the Spring Framework, and connections to the wider OSGi community were only just beginning to be formed.

Fast forward eighteen months, and Spring Dynamic Modules has become a full-fledged project in the Spring portfolio with committers from SpringSource, BEA, and Oracle. Both BEA and Oracle are using Spring Dynamic Modules to build their own OSGi-based products (see for example “WebLogic Event Server - why we used Spring”), and the Spring Dynamic Modules discussion group has almost 1000 members. The OSGi Alliance itself has formed an Enterprise Expert Group, and SpringSource is an active member.

Spring Overtakes EJB as a Skills Requirement

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 the safety for companies in adopting a particular technology.

Thus the jobtrends site of Indeed.com, a job listing aggregation site, is an important resource. It allows trends in the number of job requirements to be tracked over time, and makes it convenient to compare technologies.

New Improvements in Domain Object Dependency Injection Feature

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 behavior rich objects, since domain objects can now collaborate with the injected objects. In this blog, I discuss the latest improvements in the Spring framework in this area.

The SpringSource Certification Program

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.
