We are pleased to announce that the first milestone release of the Spring AMQP 1.0 project is now available for both Java and .NET!
Spring AMQP makes common Spring idioms available to developers who are building AMQP-based messaging solutions. For example, building a messaging application that uses RabbitMQ as a broker will feel quite similar to building an application based on Spring’s JMS support. To learn more about the project, visit the Spring AMQP Homepage. There you will find links to the Reference Manual, Forum, Issue Tracker, and more.
I’m pleased to announce we’ve just released Spring Roo 1.1.0.M2 (download here). We’ve also concurrently released SpringSource Tool Suite 2.3.3.M2, which offers the latest integration with this new Spring Roo release. For production use we recommend you continue to use Spring Roo 1.0.2, although we know a very large number of people are happily using the Roo 1.1.0 development releases as well.
SpringSource has just released a new milestone version of SpringSource Tool Suite: 2.3.2.M2. STS provides the best Eclipse-powered development environment for building Spring and Grails powered enterprise applications. Here are some highlights from the release:
Recently we released the first milestone of the Flex Addon for Spring Roo as a part of the Spring BlazeDS Integration 1.5.0.M1 distribution. This addon aims to bring the productivity and usability benefits of Spring Roo to the development of Spring-based RIAs with Flex. The below 15 minute screencast (split into two parts) serves as a quick introduction to the addon and its capabilities. Watch as we go from installation of the addon to a fully functional Flex application backed by Spring in just a handful of commands.
Virgo 2.1.0.M02-incubator is available for download. Apart from completing the “getting started guide”, this milestone dramatically reduces startup time - by as much as 5x on some systems.
This should be a further incentive for users of dm Server to migrate to Virgo: Virgo is the codebase for future development, has more liberal licensing, and now provides much faster startup.
We measured elapsed time for a warm startup (i.e. without -clean) of the Virgo web server and compared milestone M02 to M01.
In part 1 of this series, I introduced you to some of the subtleties associated with persisting domain instances with GORM. This time, I’m going to tackle relationships with particular focus on hasMany and belongsTo.
GORM provides only a few basic elements for defining relationships between domain classes, but they are sufficient to describe most needs. When I give training courses on Grails, it always surprises me how few slides cover relationships. As you can imagine, this apparent simplicity does hide some subtle behaviour that can trip up the unwary. Let’s start with the most basic of relationships: the many-to-one.
Hot on the heels of the STS on Eclipse 3.6 and Gemini Web milestone announcements, I am glad to report that the first milestone of Gemini Blueprint is available for download. Part of the Gemini project, Blueprint builds on top of the Spring Dynamic Modules v2 code base and is the Reference Implementation for the OSGi 4.2 Blueprint specification. Besides the changes reflecting the transition to the Eclipse Foundation, 1.0.0.M1 code base has been upgraded to the latest Spring framework release.
Gemini Blueprint is dual licensed under Apache License and Eclipse Public License.
Last week the Eclipse Foundation released the much anticipated next version of Eclipse. You can download Eclipse 3.6 aka Helios from SpringSource’s member distribution page. Also check out the New & Noteworthy for this release.
The Tools Team at SpringSource has been busy updating our developer tools to support Eclipse 3.6 and while we haven’t released a new version of SpringSource Tool Suite that builds on and bundles 3.6 yet, users can now install STS on top of Eclipse 3.6.
Detailed steps to install STS from our nightly update sites can be found in the installation instructions. Please carefully follow the outlined steps in the “Installing from the Nightly Snapshot Update Site” section starting on page 9.
