In the course of creating VAS, we did a lot of work to design a useful REST API.
REST is generally a very loose collection of principals that can be interpreted in many ways, so this talk would describe a more concrete idea of what a REST-ful API should look like.
In addition, the implementation of this API was done with many of the new features in Spring 3 and are a good demonstration of the power it provides.

IOC + Javascript
Thicker web clients and server-side JavaScript create complexity that must be managed through architectural patterns. JavaScript hasn't yet embraced lessons learned from other platforms, like Java+Spring. Existing JavaScript MVC frameworks are too rigid and lack sufficient architectural plumbing. Javascript needs flexible architectural infrastructure for building bigger, better apps.
In this talk, Brian and John will introduce several concepts, including JavaScript Modules and Inversion of Control, and demonstrate how they alleviate many of the dominant problems encountered when building large JavaScript apps. Attendees will gain a firmer understanding of new architectural patterns and witness tangible examples of how these patterns improve testability, refactorability, composability, division of work, and team scalability.

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!
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.
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!
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.
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>.
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.
We are pleased to announce the first milestone release of Spring Social 1.1.0!
Spring Social is an extension of the Spring Framework that enables you to connect your Java applications to Software-as-a-Service (SaaS) providers such as Facebook and Twitter.
Along with Spring Social 1.1.0, we are also releasing milestones for Spring Social Facebook 1.1.0 and Spring Social Twitter 1.1.0.
These 1.1.0.M1 releases include the following:
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.
Updates to both the Facebook and Twitter API bindings, including binding to version 1.1 of Twitter's API.
Support for OpenGraph operations in the Facebook API binding.
Support for Facebook Query Language (FQL).
In addition, several smaller enhancements and bug fixes were applied.
To get the software, download the release distribution (Core | Facebook | Twitter).
As always, the Spring Social community has been awesome at providing feedback and contributing pull requests to make this release possible. A special thanks to Jeremy Appel for contributing a rather large pull request to bring the Spring Social Twitter API binding in line with version 1.1 of Twitter's API.
These milestone releases mark the first step toward Spring Social 1.1.0. We plan to increase momentum on these milestone releases up to the 1.1.0 GA release, so expect another milestone release in the next few weeks. If you'd like to follow along or contribute, we encourage you to participate in the Spring Social Forum, report bugs or suggest enhancements, or to fork the code and contribute back via pull requests.
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.

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.
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…
Following on Juergen's talk on the upcoming Spring 3.2 release, this presentation will focus on what's new specifically in the area of Spring MVC. The presentation will explain all noteworthy features and, as is usual with every new release, there will be a lot to discuss including Servlet-based async request support, content negotiation enhancements, REST error handling, @MVC test support, and much more. The talk does not provide an overview of Spring MVC but rather assumes a level of experience and focuses on covering what's new.
About Rossen Stoyanchev
Rossen is a Spring Framework developer focusing on Spring MVC as well as Spring Web Flow. His 17+ year background includes work on trading and risk management software, investment accounting, e-commerce web applications, directory services, among others.

Extending Spring MVC with Spring Mobile and JavaScript
The modern web no longer is limited to desktop browsers. Smart phones and tablets have become an integral part of our daily lives. Web sites that may look good on a 22" monitor usually do not format and display well on a much smaller screen. Additionally, network speeds can limit the performance of a web site on mobile devices. Because of these reasons many developers and organizations are considering how to make their web sites accessible to all the various devices and screen sizes for which people are using. In this session, we will explore the functionality provided within the Spring Mobile project, and how you can use it to extend your Spring MVC application onto mobile and tablet devices. We'll then continue the discussion by demonstrating how you can leverage some of the popular mobile JavaScript frameworks in combination with Spring Mobile to provide a first class experience for your users on mobile devices.

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.
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.
