The release fixes a few bugs, release notes available from JIRA. This release can be downloaded from the project page on SpringSource.org.

• The kernel startup hard timeout limit has been increased to allow dm Server to run on slower machines.
• Documented a restriction in the OSGi web container, Tomcat <context> elements are not supported.
• Fix to the ServiceScoper class to close all input streams.
• Added support to tolerate File.list returning null occasionally, this manifested as the pickup directory wiping itself occasionally for seemingly no reason.
• Usage of @Configurable with ServerOsgiBundleXmlWebApplicationContext now works.

The project is being donated to the Eclipse Foundation as Virgo. We aim to ship a baseline release of Virgo in due course which will be functionally equivalent to dm Server 2.0. See the Virgo website for further information. Along with dm Server SpringSource will offer commercial support for Virgo.

The Spring Insight team is proud to announce the release of Spring Insight 1.0.0.M3.  This release contains a ton of new enhancements to give you more productivity and get your application to production even faster.  Spring Insight is available as part of tc Server Developer Edition and SpringSource Tool Suite but you can snag the new developer release at http://springsource.org/insight.  Setup time will take you the usual 10 seconds.

Last week, I described how Grails now treats plugins like normal dependencies that can be pulled from Maven-compatible repositories. Although this was the big new feature for 1.3, it wasn't the only one. In this post, I'll look at some of the others, starting with a feature that I only recently found out about.

Named queries

• dynamic finders, e.g. Book.findByTitleAndAuthorLike(...);
• criteria queries, which use a nice DSL; and
• HQL, Hibernate's SQL-like query language.

Develop a non-trivial Grails application and you will soon realise that you often use the same queries again and again. What should you do? The copy-and-paste technique is simple but leaves you with major maintenance issues. You could write service methods for each of your common…

The Spring Python 1.1 book is published! Spring Python takes the concepts of the Spring Framework and Spring Security, and applies them to the world of Python.

In this book, you will be writing code using dependency injection, aspect oriented programming, data access, transaction management, remoting and security. Later on in the first case study, you will be building a banking web app and see how using all these components in concert quickly meets your needs. In the second case study you will integrate Python and Java together as you build a flight reservation system.

The book is full of code…

A few weeks ago I tweeted that—incredibly—SpringSource was executing faster within VMware than as a startup. Today we announce another exciting development bearing this out.

Following our VMforce partnership with SaaS leader salesforce.com, we are today announcing a collaboration between VMware and Google, centering around the Spring programming model and SpringSource IDE and RAD tooling. Today’s announcement makes Spring the preferred programming model for Google App Engine. This is a tremendous endorsement of Spring as the best and most portable programming model for Java and opens up a new deployment opportunity for Spring developers. The demo in today’s keynote at Google I/O showcased the results from months of collaboration between SpringSource and Google engineers—most of which benefits Spring developers, regardless of where they wish to…

I'm delighted to announce that we've just released Spring Roo 1.1.0.M1. Spring Roo is the fastest way for Java developers to build Spring-based applications in the Java programming language. With the Roo 1.1.0.M1 you can build working web applications - complete with a Google Web Toolkit (GWT) front end - in as little as 200 keystrokes! Plus as usual we've concurrently released a new version of SpringSource Tool Suite (STS 2.3.3.M1) which is optimised for the latest and greatest Roo goodies!

There are over 200 fixes, enhancements and new features since our 1.0.2 release three months ago. Some…

For a long time, managing Grails dependencies simply meant putting them in your application's lib directory. Then came Grails 1.2 and the dependency DSL: you could finally declare your dependencies and have Grails automatically download them and make them available to your app. Great!

Now, Grails 1.3 has brought the dependency DSL to the realm of plugins.

So what?

1. setting up a suitable Subversion server to act as a Grails plugin repository is not simple; and
2. you can't control what dependencies a plugin brings into your application.

As for the dependencies, some plugins include libraries you don't need or (even worse) break your application. With the dependency DSL, you can explicitly exclude problematic libraries.

Those are some of the reasons why this change might be…

I'm pleased to announce the immediate availability of Grails 1.3! Followers of Grails releases will recall that it has not been long since the last major release of Grails (Grails 1.2 was released in December), but given the need to get the latest and greatest version of Groovy in the hands of developers, Grails 1.3 can be seen as the Groovy 1.7 release. The Groovy team did a fantastic job in bringing all sorts of excellent new additions to the Groovy language such as annonymous inner/nested classes, an AST builder and power asserts (my personal favourite), all of which are now available in…

Another week, another important announcement. The SpringSource division of VMware today announced that we have entered into a definitive agreement to acquire GemStone Systems, a leader in data grid technology.

This acquisition, like our recent acquisition of Rabbit Technologies, adds another crucial building block of private and public cloud to our middleware portfolio. Like Rabbit and SpringSource and VMware’s other products, GemStone technology is valuable in both today’s enterprise scenarios and tomorrow’s cloud world. The acquisition also adds an important middleware capability to our…
