Don't forget that Spring users can ask questions in the community forum and identify issues in JIRA as well. Please keep up the good work so that we can continue to make all the Spring projects better and better. European developers can learn more about Spring 3.0 at the one day S2G Forum in Munich on March 18th, or at the other S2G Forums in London and Amsterdam (dates to be announced soon).

There are some common concerns of users of Spring Batch and Spring Integration, and we get asked a lot about how they fit together. Spring Batch Admin 1.0.0.M2 was released recently, and it makes heavy use of Spring Integration, so it is a good vehicle for looking at some specific use cases, and that is what we plan to do in this article.

Spring Batch Integration

Part of the 1.0.0.M2 release was the Spring Batch Integration module, recently migrated from Spring Batch and given a new home with Batch Admin. Many of the Batch-Integration cross over use cases are either implemented or demonstrated in Spring Batch…

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.

Jeremy Grelle
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.

In my last entry, I walked you through several enhancements in Spring 3 for web application development. A number of you expressed interest in a follow-up entry focused on Ajax remoting. Spring 3 provides a lot in this area to take advantage of. Read on, and I'll walk you through it.

Spring and Ajax Overview

For the purposes of this article, when I say Ajax, I'm talking about the web browser's ability to communicate with a web server asynchronously using JavaScript. On the server-side, Spring provides the programming model for defining web services, including services consumed by JavaScript clients. On the client-side, nobody rolls their own Ajax framework these days, either. Most use an established JavaScript framework such as jQuery or Dojo…

After our mad dash to the final release of Spring Roo 1.0.0 on New Year's Eve, many users have asked for an introductory screencast.

In this 5 minute screencast you will see how to:

• Develop a simple "contact manager application" using the Roo shell
• Import and edit the project our free IDE, SpringSource Tool Suite (STS)
• Run the Roo-provided integration tests in STS
• Modify the application and understand ITD round-trip support
• Deploy to your IDE's web container
• Use the scaffolded web user interface
• "Push-in refactor" to move source code between Java source files and ITDs
• Remove Roo from the project

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…

Today we will be releasing version 2.0 of the dm server. This represents a major milestone for the project, and for enterprise application development with OSGi in general. I’m delighted to now be able to reveal the next step in the dm Server journey: we have submitted a proposal at Eclipse.org to continue development of the dm Server as part of the Eclipse RT top-level project. The Eclipse nickname for the project is Virgo.

Quick links:

• Virgo proposal document at Eclipse.org
• Virgo community forum

What does this mean for users of dm Server?

The move to Eclipse.org has a number of practical implications for users of dm Server:

• Project hosting, home pages, forums, and downloads will all be moved to Eclipse.org infrastructure
• The license will change from the current (largely) GPL license, to the Eclipse Public License (EPL)
• It will be much easier for other organizations and community members to get involved in the ongoing development of Virgo

The combination of the license change and community hosting at Eclipse.org opens the codebase to a much broader set of users and developers.

The follow-on release of dm Server will be developed and released from Eclipse.org.

Why is SpringSource making this change?

The dm Server represents a significant amount of intellectual property (IP) and has been in full-time development for over 2 years. Why would SpringSource move this project to Eclipse.org?

We set out with a vision to make modular application development a…
