News and Announcements  

Of course the sessions at SpringOne 2GX 2011 covered Spring, Groovy and Grails in amazing detail, but cloud workloads were hot topics of discussion last year as well. In this presentation, pioneering technologist Derek Collison gives a detailed breakdown of Cloud Foundry - Inside the Machine. Derek gives a deep analysis of Cloud Foundry’s architecture with specific details on the Cloud Controller, the Service Provisioning Agent, the Droplet Execution Agent, and the Messaging System. If you want to learn about the technology behind the world's first open platform-as-a-service then this presentation is for you.

Many thanks to InfoQ for coming to Chicago to record so many of the fantastic SpringOne 2GX presentations.

Another session from SpringOne 2GX 2011 gives a detailed guide to Identity Management with Spring Security. Spring developer and also Cloud Foundry engineer, Dave Syer, covers Single Sign On, security standards (including SAML, OpenID, OAuth, SCIM, JWT), how Spring Security can fit in, as well as demoing identity management as a service. Dave has tackled some of the most complex problems possible in enterprise Java and this presentation provides a great guide for developers interested in security identity in distributed environments.

As datacenters virtualize more and more workloads, it becomes important to understand the potential impact on the Java servers that may be running your applications. At SpringOne 2GX 2011, Ben Corrie provided a thorough overview of Java memory management, how things work differently in virtual environments and what you can do about it to avoid problems. This includes a practical introduction to Elastic Memory for Java (EM4J) that is a feature of the VMware vFabric platform.

On the way to Spring IO conference I'd like to announce the availability of Spring Data MongoDB 1.0.1. It's mainly a bug fix release covering a few glitches found in the first major release. We've fixed some issues in entity mapping, query execution and added a converter for UUIDs out of the box.

The release is available from our Maven repository and from Maven Central as well. To learn more about the project, visit the Spring Data MongoDB Page. Looking forward to your feedback on the forum or in the issue tracker.

If you missed the recent Cloud Foundry webinar that covered Spring development, you can catch the video replay on the Cloud Foundry YouTube channel. In this video, Ramnivas Laddad shows you how to take a real Spring application and target it to Cloud Foundry using both STS and the vmc command line.

Be sure to thumbs up the presentation if you find it useful and subscribe to the SpringSourceDev channel to see other recordings and screencasts.

Dear Spring Community,

I am happy to announce the release of Spring Data JPA 1.1.0 RC1 as well as 1.0.3 GA. The release candidate includes a ton of new features and a variety of bug fixes. Here's a brief list of the most important ones:

• Support for locking
• Support for @IdClass in entities
• Support for LessThanEqual and GreaterThanEquals, True/False keywords in query methods
• Added CDI integration for repositories
• Improved parameter binding for derived queries for null values

The CDI integration was contributed by Dirk Mahler of Buschmais to a large degree. For a full list of changes see the changelog. Quite a few of the bugs fixed were back ported so we definitely recommend to upgrade to 1.0.3 as well as playing with the release candidate to help improving the final release. The 1.0.3 GA release can be obtained from Maven central while the release candidate is available via our milestone repository at http://repo.springsource.org/libs-milestone.

Eclipse’s Business Intelligence and Reporting Tools (BIRT) project is an open-source project based on the popular Eclipse IDE. In this article, BIRT Evangelist Jason Weathersby and Spring Developer Advocate Josh Long introduce BIRT and a Spring integration library to make it easy for Spring beans and applications to consume, and participate in, BIRT reports. The article covers:

• Integrating the BIRT engines in Spring MVC
• Accessing Spring beans from the BIRT Viewer
• Using Spring Remoting to access Spring Beans from a BIRT report

Many thanks to Jason Weathersby and the BIRT team for collaborating on this great tutorial and integration.
