Welcome to another installment of This Week in Spring! I'm writing the back of the room during Adrian Colyer's amazing keynote at SpringOne On The Road - London event.

   Also, be sure to check out part 2, this Wednesday, May 3rd for both Europe and North America!

2. Blogger Daniel Sawano has put together two blogs introducing how to use Spring MVC with Scala. The first blog introduces a simple Scala-Java hybrid Spring MVC application setup, and the second blog introduces how to build a more advanced Spring MVC example with RESTful endpoints using Scala. Nice job, Daniel!
3. Our pal Jan Machacek over at Cake Solutions has put together a really cool blog on how to use Akka (an actor framework), Spray (an HTTP framework on top of Akka) and Spring together.
4. Blogger mkyong has a nice introduction on how to use Google App Engine to setup a RESTful Spring MVC application on Google App Engine.

14. Check out this blog if you want a narrated example introducing how to do Spring MVC 3.0, and Hibernate, with annotations.
15. AMQP's a powerful technology, and RabbitMQ, the leading AMQP-based message broker, is even more so. However, one common question I get is: what other implementations are there? This blog has the top 5 implementations (though, clearly not in order, because RabbitMQ would have to be #1, otherwise!)
16. Want to manage JTA transactions on JBoss AS 7 using Spring and Hibernate? This gist by ggerard shows one possible configuration.
