Last October, at SpringOne2GX, I introduced the Spring Scala project to the world. Since then, I've also presented this project at Devoxx. In this blog post, I would like to give further details about this project and how you can use it in your Scala projects.

Why Spring Scala?

The goal of the Spring Scala project is simply to make it easier to use the Spring framework in Scala. We believe that there are many Spring users out there who want to try Scala out, but do not want to leave their experience with Spring behind. This project is meant for those people.

Obviously, you can use the (Java) Spring Framework in Scala today, without Spring Scala. But doing so will be awkward in certain places. Just like any programming language, Scala has its own, different way of doing things, and using a pure Java framework like Spring in Scala will just feel "too Java-esque". Spring Scala tries to fix…

We gave a talk on IOC + Javascript at SpringOne 2GX. Front-end web application architecture seemed to be quite a hot topic at the conference, in general, and our talk seemed to be very well received. Here are the video and slides from the talk.

We'll also be starting a blog series about architectural patterns for modern Javascript web apps, featuring posts from members of SpringSource's new front-end architecture team, S2JS. The posts will expand on the concepts presented in our talk, as well as those presented by Scott Andrews and Jeremy Grelle in their talks.

The first post in the series is coming next week. Until then, we hope you enjoy the video and the slides.  If you'd like to get a head start, you can browse the demo app's source code…

Wow guys! December 4th already! Time sure flies when you're having fun!

Welcome back to another installment of <EM>This Week in Spring</EM>. This week, I'm in Beijing for <a href="http://springonechina.cloudfoundry.com">SpringOne China</a> and, next week, I'm off to India for <A href="http://springoneindia.cloudfoundry.com/">SpringOne India</a>. If you're in Beijing, Bangalore or Hyderabad, I'd love to see you at these events!

Alright, let's get on with this week's roundup!

1. Mark Fisher gets the ball rolling this week with a very nice present: Spring Integration 2.2.0.GA has been released! The new release is well described in the blogs on the various new features referenced in the release announcement, so be sure to check it out!

Welcome back to another installment of This Week in Spring! If you're in the states, then I hope you're well rested from a hopefully very pleasant holiday weekend, because we've got a lot to cover this week!

I hope you find this roundup useful. If you should ever want to peruse previous weeks' roundups, we've recently created a This Week in Spring hash tag for the blog archives.

Anyway, we've got a lot to cover this week, so let's get on with it!

1. Chris Beams has announced that the Spring Framework 3.2 RC2 has been released, consisting largely of bugfixes and refactoring as the project nears GA.
2. Andy Wilkinson has announced the release and availability of the Spring Migration Analyzer, a command-line utility that analyzes enterprise Java applications and produces a report describing the application and how it can be migrated to Spring. Input an EAR file, get a migration effort report. It supports WebLogic, WebSphere, Java EE and JBoss in the milestone release, but we are looking for community support to make it better for GA!
3. Catch the latest in the Spring Data webinar series on Dec 13th -- Data Access and Processing with Spring Data, Hadoop, Batch, Integration. We are also have a webinar on Spring Data Gemfire on Dec 6th: The Data Renaissance: Going in-Memory with VMWare vFabric GemFire 7.0 and Spring.
4. If you have missed the other webinars in the Spring Data Webinar series, check out the SpringSource Dev Youtube channel for recently published replays on: Data Access with Spring -- Getting the most out of JPA, JDBC and REST and Introducing Spring for Apache Hadoop.
5. Gary Russell has announced that Spring Integration 2.2.0.RC3 has been released.
6. Spring Social 1.1.0 has been released. The new release includes easier XML and Java configuration, tighter adherence to the latest OAuth 2 specification drafts, including HTTP Basic client authentication and support for Resource Owner Credentials Grant and Client Credentials Grant, and updates to the Facebook and Twitter API bindings.
7. Jens Schauder has a nice post on creating new Spring beans on demand using the singleton scope.
8. The Java How to Program blog has a nice roundup on

     <a href="http://www.hubberspot.com/2012/10/how-to-use-component-annotation-for.html">How to use <CODE>@Component</CODE> 
     annotation to automatically configure Spring beans</a>.
   

9. This is a nice post on how to implement the chain-of-responsibility pattern using Spring and @Autowired (or alternatively @Inject).
10. Viral Patel's back at it again, this time with a post on Spring 3 MVC interceptors.
11. The Mkyong blog has another nice post up on Spring and Java threading example using the Spring thread scope.
12. DZone has a nice post up on easy integration testing with Spring and the JUnit 4 support.
13. I recently wrote up a version of a tutorial on getting started with SpringSource Tool Suite and Spring for beginners.

It's my pleasure to announce that we've released the first milestone of Spring Migration Analyzer (SMA), a command-line utility that analyzes enterprise Java applications and produces a report describing the application and how it can be migrated to Spring.

Why migrate an application to Spring?

We see two main reasons when people choose to use Spring. Firstly, Spring offers the greatest range of deployment options including cloud and PaaS, allowing you to deploy your application to lighter-weight runtimes with lower operating costs. Secondly, as Adrian recently explained Spring provides access to a host of technologies that are at the forefront of enterprise Java.

When it comes to considering the migration of an existing application to Spring, it's typically the deployment flexibility that motivates the move as it can significantly reduce the application's operating costs.

Using SMA to analyze an application

To get started with SMA, download the distribution. Once it's downloaded, unzip it:

unzip spring-migration-analyzer-1.0.0.M1-dist.zip

With JAVA_HOME set, you can then run the migration-analysis script to…

Scripted, a JavaScript editor from VMWare was announced on this blog last month. In this article we'll take a look under the hood at Scripted's Dependency Analysis Engine. But before diving into the details, lets motivate why we need it.

Main Motivation: Cross-file Content Assist

To provide a great JavaScript editing experience, Scripted needs to provide accurate suggestions about the functions, methods or identifiers you can use in your current editor context.

[caption id="attachment_12178" align="aligncenter" width="533" caption="Cross-file Content Assist"][/caption]

Two components work together to achieve this goal:

• a fine-grained type inference analysis engine
• a coarse-grained dependency analysis engine

The inference engine parses your code and walks every declaration, statement and expression. This allows it to determine what identifiers are valid in a given context, and make good guesses about the kinds of things that may be stored in these variables. This information is then used to make content assist suggestions.

If you wanted to simply put all your code into one big file, then a good quality inferencer alone would be sufficient to provide some pretty good content assist. In reality, projects will be divided…

Wow! Guys, can you believe we are again staring down the end of the year? Time sure flies! In the US, this is the week of Thanksgiving, a holiday where we're supposed to take a moment and reflect upon the things for which we're grateful. I am (and I'm sure I speak for the team in saying that we are..) eternally grateful for you guys, the wonderful, vibrant and engaging community surrounding Spring, RabbitMQ and Cloud Foundry that makes putting together this roundup such a pleasure every week.

With that, let's get on with the news:

1. Thomas Risberg has announced that the Cloud Foundry Maven plugin 1.0.0.M4 is now available.

Welcome back to another installment of This Week in Spring! I started this week back in the lovely Sofia, Bulgaria for the Cloud Foundry Open Tour event, talking to a packed audience about building Spring applications on Cloud Foundry. Now, I'm in Antwerp, Belgium, at the Devoxx conference where I'll present on what's new in Spring 3.2, Cloud Foundry and more. If you're here, I invite you to come visit the SpringSource booth and see some of the talks on Spring that I - and others - will be giving.

1. 		Roy Clarkson has announced not one, but two releases of Spring  Mobile this week! 
   

   Spring Android 1.0.1 has been released. This release includes a change to support BlackBerry 10 mobile devices. BlackBerry 10 mobile devices are now resolved as a mobile device when using the LiteDeviceResolver. Then, he released the
   1.1.0.M1 release, which folds in the 1.0.1 support as well as tablet support in site preference handling and site switching, support for Java-based container configuration, and support for servlet based configurations.

2. Thomas Risberg has announced the GA release of Spring Data JDBC extensions with QueryDSL and Advanced Oracle support.
