We're delighted to announce the general availability (GA) of Spring Roo 1.0.0.

Spring Roo is a next-generation rapid application development tool for Java developers. With Roo you can easily build full Java applications in minutes. It differs from other tools by focusing on:

• Higher Java productivity: Try the ten minute test and see for yourself.
• Stock-standard Java: Roo uses the Java APIs and standards you already know and trust.
• Usable and learnable: Roo features an extremely high level of usability and an advanced shell.
• No engineering trade-offs: Roo has no runtime portion and does not impose any CPU, RAM or disk storage cost.
• Easy Roo removal: Roo can be easily removed from a user project in under five minutes.

This release follows some eight community releases (A1, A2, M1, M2, RC1, RC2, RC3, RC4) and extensive feedback. Before reaching Roo 1.0.0 we already had over 1,000 forum posts and some 500 Jira issues logged. There's already been dozens of conference and JUG presentations on Roo, several third-party add-ons and there's…

I'm very excited to announce that Bundlor 1.0.0.RC1 is now available. There have been numerous changes to Bundlor since the M6 release including additions to detection and warning criteria as well as improvements to the ANT and Maven configurations.

This milestone marks feature-complete status for the 1.0.0 release. Baring any major issues, this candidate will be released as 1.0.0.RELEASE shortly.

Detection and Warning Criteria

Bundlor now detects Java types in the following locations:

• Java Types
• Spring Context Files
• Blueprint Service Configuration Files
• Web Application Files
• Contained JARs
• JPA Configuration Files
• Hibernate Configuration Files
• JSP Files
• Log4J Configuration Files
• Static Resources

Bundlor also scans the its generated manifest for the following issues and generates warnings based on them:

• Unlikely Import Version Ranges
• Importing of Exported Packages
• Manifest from Signed JAR
• Imports Unversioned
• Exports Unvesioned
• Missing Bundle-SymbolicName
• Missing Manifest-Version

Standardized and Simplified Configuration

One of the most glaringly bad parts of Bundlor up until the RC1 release was the inconsistency of features and configuration across the various front ends (command-line, ANT, Maven). RC1 has unfortunately had to change the configuration parameters of all of these but the end result is consistency and in many cases simplification of Bundlor's configuration.

Please see the Bundlor documentation for the configuration options for your…

We're pleased to an announce the release of Spring Security 3.0.0.

Thanks to everyone in the community who has helped out by testing the milestone and release candidate versions and providing feedback.

Check out the project website for a list of supported features, and also the release announcement in the community forum for information on changes which may affect you if you are upgrading.

Look out for compatible releases of Spring Security Extensions projects (such as our Kerberos support) in the new year.

Continuing the release train, today we are excited to announce the general availability of Grails 1.2 final. Representing the most stable and performant Grails release yet, Grails 1.2 is a significant new release of the premier dynamic language framework for the JVM.

As well as featuring all of the goodness of Spring 3, this release has a number of significant new features for Grails users:

• Dependency Resolution DSL: Based on Ivy, Grails users now have full control over JAR dependencies including those inherited from the framework and any installed plugins.
• Better Spring Integration: As well as supporting component scanning, Grails now allows you to implement controllers as regular MVC @Controller instances.
• Named Query Support: It is now possible to define named, reusable criteria queries in GORM that can be combined with regular dynamic finders making querying a lot more DRY
• Improved Performance & Memory Consumption: The performance of Grails' view layer (GSP) has been significantly improved resulting in up to 2-3 times throughput. We've also improved Grails' memory consumption and the need for additional PermGen by implementing precompilation of GSP views.
• Named URL Mappings: It is now possible to name an individual URL mapping which allows you to create more explicit and expressive links inside GSPs
• Refactored Testing Infrastructure: Grails' testing infrastructure is now completely pluggable to new providers. The default JUnit provider is still present, but new testing providers can be implemented that can be run in specific phases (such as 'unit', 'integration' and 'functional' phases). There is already a Spock plugin that takes advantage of this new infrastructure, allowing BDD style testing.
• Pluggable Web Containers: Grails now allows different development time containers to be installed and plugins for both Tomcat and Jetty are available.

In addition to these headliners there are literally hundreds of bug fixes and small improvements some of which are described in much more detail in the release notes. Grails 1.2 can be downloaded from the Grails site at the usual place.

As well as the continued, significant contributions to the release from the community, one of the most enjoyable aspect about this release has been the active collaboration amongst the Spring, Tomcat…

The Groovy development team and SpringSource are very pleased to announce the final release of Groovy 1.7, the most popular and successful dynamic language for the JVM! After two betas and two release candidates, we're are happy to deliver this new and very important milestone to our ever-growing user base.

Over the years, the Groovy project has managed to grow a community, but not only that, a very rich and active ecosystem of Groovy-related projects: the Grails web stack, the Griffon swing application framework, the Gant and Gradle build solutions, the Gaelyk lightweight toolkit for Google App Engine, the Gpars parallel system, the Spock testing frameworks and the GMock mocking library, the CodeNarc and GMetrics quality tools, and many more! With all…

Second in a series of posts on "Spring 3 Simplifications" started yesterday by Keith, I'd like to provide a very brief and hands-on introduction to Spring's new @Configuration annotation and related support.

As those that followed the Spring JavaConfig project will know, a @Configuration-annotated class serves much the same role as a Spring XML file. It provides a code-centric way of declaring Spring bean definitions using nothing more than methods and annotations. You might call it Plain Old Configuration* :) This means that for simple situations, no XML will be required!

Let's get started. To demonstrate @Configuration functionality, I've created a very simple project in the new spring-samples SVN repository. You may want to sync up and…

As Juergen and Arjen have mentioned, Java developers everywhere have a smooth upgrade with Spring 3.0. Now that Spring 3 is out, I'd like to take you through some of the new MVC features you may not know about. I hope you find these features useful and can start putting them to work in your web applications immediately.

This is also the start of a series on "Spring 3 Simplifications", so expect more posts like these in the coming days and weeks.

Configuration Simplification

Spring 3 introduces a mvc namespace that greatly simplifies Spring MVC setup. Along with other enhancements, it has never been easier to get Spring web applications up and running. This can be illustrated by the mvc-basic…
