Dear Spring Community,

I'm pleased to announce that the 1.0.2 maintenance release of Spring BlazeDS Integration, the open source solution for building Spring-powered RIAs with Adobe Flex, is now available.

Download | Reference Documentation | JavaDocs | Changelog

Along with a number of bug fixes and minor enhancements, we have added full support for using Spring Security 3 to secure a Flex application using the same integration mechanisms as we've previously provided only for Spring Security 2.0.x. In order to effectively demonstrate this support, we've added an additional profile to the Test Drive's Maven build that will configure the application to use Spring 3 and Spring Security 3. See the reference guide for details on how to trigger this alternate profile.

As always, I encourage anyone interested to get involved by trying out the release and giving us feedback in the community forum and Jira. We continually get great feedback from people having success with Spring BlazeDS Integration in their projects, and we look forward to hearing more about your experiences. We'll now be shifting focus entirely to version 1.5, which will add support for BlazeDS 4, and will bring with it a number of new features, including an addon for Spring Roo. This is a great time to make yourself heard if you'd like to help shape the future direction of the project.

Spring BlazeDS Integration Lead

We're pleased to an announce the release of Spring Batch 2.1.0. Thank you to all the people who have been tracking the milestones and providing feedback.

This first SpringSource S2G Forum will be held on March 18th, 2010 at the MOC Veranstaltungs- und Ordercenter in Munich, Germany. The event is a one day, multi-track, lecture-based forum that gives developers, engineers and IT managers the latest information about enterprise Java technology. The tracks are:

• Essential Spring: The sessions in this track cover how to use the new Spring 3.0 technology, build rich web application with Spring Web projects, integrate enterprise systems, and how to get the most out of Spring productivity tools like the brand new Spring Roo.
• Enterprise Production Systems: Detailed discussions about optimal production use of Tomcat, tips on production application monitoring, how to intelligently virtualize Java workloads and run Spring and Grails applications in the cloud.
• Groovy & Grails: These talks provide an update on the latest versions of Groovy and Grails, give Spring developers practical tips on how to get started with Grails, and introduces developer to the vast eco-system of Grails plug-ins.

From development to the datacenter and into the cloud, the S2G Forum is the optimal way to learn how to build and run tomorrow’s applications today. Be sure to register now or watch out for future S2G Forum events in the Netherlands and England.

Dear Spring Community,

I'm pleased to announce that Spring Python's 1.1.0.M1 is available. Spring Python takes the concepts implemented by the Spring Framework, and applies them to Python.

Download | Reference Documentation | Python API Docs | Blog

This is the first milestone of Spring Python's newer 1.1 baseline, which includes new features and API improvements.

Since this project's inception back in 2006, the community has provided us with excellent feedback throughout the development process. This project has also had significant contributions from new Spring Python committer Dariusz Suchojad who joined the team several months ago.

I encourage anyone interested to get involved by trying out the new functionality and giving us feedback in the community forum and JIRA as we proceed to add newer functionality to serve the Spring Python community.

Spring Python Project Lead

Another Infoq video presentation has been posted that gives an Overview of the Spring 3.0 Web Stack. The session was recorded at last October's SpringOne 2GX 2009 conference and features, Keith Donald, SpringSource's web guru. Keith provides some quick notes for viewers:

• The December GA release of Spring 3.0 shipped the additional Spring MVC simplifications predicted in this talk, including:
  • A dedicated 'mvc' namespace for simplifying Spring MVC setup
  • Automatic registration of type converters based on what is present in your classpath. This includes automatic setup of JSON (Jackson), XML (JAXB), and Joda Time support.
  • Support for annotation-driven formatting with @NumberFormat and @DateTimeFormat
• Community members interested in these capabilities can read more in this blog entry. The petcare sample application referenced in this presentation can also be accessed in the Spring Samples SVN repository. This sample app is directly importable & runnable with SpringSource Tool Suite.

We're pleased to an announce the release of Spring Security 3.0.1.

This is a minor bugfix release, following on from the recent 3.0.0 release. Please see the changelog for a list of issues which have been addressed.

At the start of May 2009 we announced we were working on a new approach to joint compilation for mixed Java/Groovy projects in Eclipse. We are pleased to now announce the final release of Groovy-Eclipse v2.0.0, based on that new technology. During the months of development we have rebased (and almost entirely rewritten) version 1 of the Groovy-Eclipse plugin, with the goal of offering first class Groovy support in the Eclipse IDE, comparable to the experience Java developers have in Eclipse. The most important new features that Groovy-Eclipse 2.0.0 provides are:

• a new approach to compiling joint Groovy-Java code that does not require a stub compiler
• advanced and extensible content assist
• vast speed and memory improvements over previous releases
• debug support
• deep integration with the Java Development tools

Also, over 380 bugs have been addressed since the previous release. See the release notes. The Eclipse update site is available here:

• http://dist.springsource.org/release/GRECLIPSE/e3.5/

Please comment on the roadmap if you want a say in the planning of future releases.
