News and Announcements  

What a week! So much to talk about and scarcely enough minutes in the day to manage. Without any further ado, let's get on to it!

1. Jonathan Brisbin has announced the availability of Spring Data REST 1.0.0.RC1 . Spring Data REST helps you provide a RESTful interface for your JPA-based repositories.
2. Oliver Gierke has announced Spring Data MongoDB 1.0.2.GA. The new release has plenty of bugfixes and improvements, so check the changelog for more.
3. Wonder what happened to the RabbitMQ webinar that was briefly on the SpringSource events calendar? It was rescheduled (slight schedule mishap), but it's back and you should definitely mark your calendars with the updated dates. It figures to be an amazing event.
4. Our pal Gordon Dickens - a world class trainer and engineer - has been very busy recently. If you haven't been following his blog recently, you missed an introduction to the SpringSource Tool Suite - including its composition and value-added features, and answers some common questions. Besides the great post on Spring 3.1's constructor namespace that we saw earlier this month, he also had a great post on converting from Spring OSGi projects to the Eclipse Gemini Blueprint namespaces for bundles. Nice job, as usual, Gordon!
5. Andy Chan has a nice post introducing how to use Spring Security 3.1.0 to talk to Microsoft Active Directory for authentication. Nice job, Andy!
6. Ben O' Day has put together a wonderful post on using Spring AOP to implement basic performance monitoring.
7. The Keyhole Software blog has a couple of very interesting blogs introducing Spring Batch: the first introduces the high level concepts and the second introduces some actual code. Definitely worth a read.
8. The Stardog blog (merely uttering that is fun..) has a a very cool example introducing how the Stardog RDF database server could work with Spring by way of an example: the Stardog Petstore! So cool...
9. Andriy Redko has a nice post on using Redis with Spring Data Redis.
10. Ken Rimple, co-author of Manning's Spring Roo in Action, has put together a nice post on using Spring Roo and Spring Webflow.
11. Michal Letynski has a nice post on using Spring 3.1's support for the @Valid annotation on @RequestBody controller method arguments.
12. I suspect we probably covered some of these before, but just to be sure, I wanted to point everybody to this series of blogs introducing the concepts of AOP, and how they're implemented in practice using the raw JDK, Spring's AOP and AspectJ, which Spring has fantastic support for. For the other blogs, simply scroll to the bottom of the page and you'll find links.
13. Madhusudhan Konda, author of O'Reilly's Just Spring and Just Spring Integration, has a new book - this one, called Just Spring Data Access, which introduces the nitty gritty of the core data-access technologies in the Spring framework (it does not, however, introduce the Spring Data technologies). While I haven't read it (though I'll be sure to read it eventually and possibly write a book review!), it looks interesting.
14. Arnon Rotem-gal-oz has written a good over-coffee introduction to AMQP and RabbitMQ terminology (if not their application. For that, you might check out this blog introducing the Spring support for JMS and AMQP ).
15. The VoltDB blog has a pretty nice writeup of how to implement repositories with Spring and VoltDB to build high throughput web applications. Another great post from the VoltDB blog talks about using the Spring Converter API with VoltDB's Data Objects. The idea is a bit unusual, but pretty slick when you think about it: let Spring's generic converter registry handle converting Volt's notion of record sets (objects of type VoltTable) into regular, domain-specific objects. You codify the recipe once - as a Spring Converter, and then simply reuse it later. In other data-access strategies, this same effect is achieved using, for example, the RowMapper callback interface, which lets you codify and reuse the recipe for converting a JDBC ResultSet into a domain-specific object. Finally, all of these blogs come to a head in this blog introducing the performance tests done against the previous application.

I'm pleased to announce the release of Spring Data REST 1.0.0.RC1! Beyond a number of bug fixes, this release adds support for paging and sorting and makes it easier to integrate Spring Data REST into an existing Spring MVC application.

New functionality includes:

• Paging - Add URL parameters like "page=2" and "limit=20" to control the paging of large result sets.
• Sorting - Add URL parameters like "sort=name" to control the sorting of result sets.
• Integrate with existing Spring MVC applications - Now you can easily integrate Spring Data REST into an existing Spring MVC application by simply including a JavaConfig bean into your own configuration.

New documentation includes:

• Paging and Sorting
• Adding Spring Data REST to an existing Spring MVC Application

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.

This week the I'm at QCon New York talking to people about Spring, Cloud Foundry, vFabric, and much more. Attendees at QCon conferences always keep things interesting with great questions and ideas. As usual, though, the internet has given us a lot of great content to look at this last week, so let's dive right into the roundup!

1. If you missed Gary Russell's excellent webinar introducing managing and monitoring of Spring Integration applications, don't worry, the video is on the SpringSource YouTube channel.
2. Details of the new release of Spring for Apache Hadoop 1.0.0.M2 are available. For information on the project itself, check out this in-depth blog of the highlights by Spring for Apache Hadoop contributor, Costin Leau.
3. James Bayer has a great post introducing how to setup Apache Tomcat 7 as a server on Cloud Foundry using the recently announced standalone process support.
4. Aljona Murygina has a great post on using Spring's asynchronous execution and scheduling support.
5. The Codecentric blog has a nice post on using Spring technoloies to create your own RSS reader! Definitely worth a read!
6. InfoQ has a nice post on the recently announced Spring Android 1.0 release.
7. If you missed Spring Data contributor and ninja Oliver Gierke's talk at Øredev on Spring Data, Data Access 2.0, then be sure to check out the recording!
8. The Cake Solutions blog has an interesting post on getting around a possible hangup of using Spring's AOP load time weaving with Specs2 tests.
9. The Craftsman Spy framework has an interesting post on logging with JDBC using their logging JDBC driver classes and Spring. This driver lets you insert yourself between the actual JDBC driver and the API calls made to the JDBC driver where you can get visibility into the arguments and operations made against the driver. Very cool!
10. The RabbitMQ blog has a post on using STOMP with RabbitMQ to build Websockets-based applications. Very cool stuff!
11. VMWare's recent vFabric release, 5.1, has updated the version of the RabbitMQ messaging broker included in the suite to 2.8.1.
