Welcome to another Installment of This Week in Spring The Cloud Foundry Open Tour is well underway, and have been thus far very good events to attract community.

There are still some (well, there were yesterday!) early bird spots in the upcoming shows in <a href = "http://opentour.cloudfoundry.com/2012/austin">Austin</A>, <a href = "http://opentour.cloudfoundry.com/2012/washington">Washington D.C.</a>, <a href = "http://opentour.cloudfoundry.com/2012/kiev">Kiev</A>, <a href = "http://opentour.cloudfoundry.com/2012/moscow">Moscow</A>, and <a href  = "http://opentour.cloudfoundry.com/2012/london">London</A>, so book now. 

1. Some of the wonderful content from the Spring I/O conference is now available online! The conference, held in Spain in February of this year, is conducted in both Spanish and English, so there's a lot to like no matter which language you speak. Adrian Colyer's keynote session is super, once you get past the audio problems at the beginning. I couldn't find a SpringIO-specific hash tag, but you can pick them out of the other videos pretty easily by scrolling down. Stay tuned, there should be even more content posted, soon.

Welcome to another installation of This Week in Spring. As usual, we have a lot to cover. As this post goes up, the Cloud Foundry Open Tour is underway in Beijing, and coming to a city near you, soon. This show's a very unique opportunity to learn more about Cloud Foundry and Spring from the experts - don't miss out, register today.

1. Spring web dude Rossen Stoyanchev announced that Spring Web Flow 2.3.1 has been released. This is a maintenance release featuring an upgrade to Spring 3.1.1, and JavaServer Faces 2.1.7 along with a number of bug fixes.
2. SpringSource Tool Suite lead Martin Lippert announced the release of the Cloud Foundry Integration for Eclipse 1.0. This release brings a complete, cohesive Cloud Foundry integration for all Eclipse distributions, including the SpringSource Tool Suite.
3. Martin also announced the release of SpringSource Tool Suite release, 2.9.1, featuring new features and bug fixes.

<LI>    <a href = "http://www.springone2gx.com/conference/speaker/mark_fisher">Mark Fisher</A> and <a href = "http://www.springone2gx.com/conference/speaker/thomas_risberg">Thomas Risberg</A>'s epic talk from <a href = "http://www.springone2gx.com">SpringOne 2GX 2011</A>  - <EM><A href = "http://www.infoq.com/presentations/Architecture-Choices-for-Scalable-Cloud-Apps">Architecture Choices for Scalable Cloud Apps</A></EM> -  that introduces how to build scalable architectures in the cloud using technologies like Spring Integration and Cloud Foundry is now up on InfoQ.

4. Maciej Walkowiak has a blog that introduces how to use Spring 3.1 profiles in conjunction with some custom Tomcat configuration to activate Spring profiles without changing the deployed binary.
5. Michal Jastak has put together a wonderful post introducing how to use Spring MVC 3.1's support for flash attributes.
6. Tobias Flohre is at it again, this time with two posts on Spring Batch. The first post introduces the basics of transactions in Spring Batch, and the second post introduces some of the finer points of restarting cursor-based readers and writers.

7. Artur Mkrtchyan has a great post introducing both how to install Redis (a fast, highly optimized data-structure server) and how to use Spring Data Redis (part of the Spring Data umbrella project that facilitates access to the wide varieties of so-called NoSQL and big-data stores) to build Spring applications that talk to Redis.

Introduction

Among those are a number of things which simplify the complicated and tedious problems often associated with data binding. In general, data binding is made very simple by Grails as it offers several techniques for binding maps of data to graphs of objects.

It is important that application developers understand the implications of each of those techniques in order to decide which is most appropriate and most secure for any given use case.

Web Application Data Binding Overview

Consider a domain class which looks something like this:

Code Listing 1

class Employee {
    String firstName
    String lastName
    BigDecimal salary
}

Outlook

Welcome to another installment of This Week in Spring. There is a lot to look at this week with much of the excitement around the just released Spring for Apache Hadoop project, which provides a very, very powerful Spring API integration for Apache Hadoop, an open source framework originally designed to support map-reduce style batch processing solutions.

</P> 

1. Costin Leau kicked things off with the announcement of Spring for Apache Hadoop 1.0.0.M1 last week. I can't explain it any better than Costin does, so I won't bother. From his post:

   Whether one is writing stand-alone, vanilla MapReduce applications, interacting with data from multiple data stores across the enterprise, or coordinating a complex workflow of HDFS, Pig, or Hive jobs, or anything in between, Spring for Apache Hadoop stays true to the Spring philosophy offering a simplified programming model and addresses "accidental complexity" caused by the infrastructure.

   What are you waiting for? Go! Check it out! When you're done, you might check out the other coverage of the event, as well. As you might expect, a lot of people blogged about it, too.

   <LI> What are you guys doing in two days, on March 8th, 2012? I'll be at the Native Android Development with Spring for Android webinar that introduces native Android development practices, resource management and the Spring for Android integration library, which makes the whole process more natural for developers that wish to interface with services on the server side. 
   	 There are, as usual, two editions, one <a href= "http://www.springsource.org/node/3482">for North America</A> and <a href = "http://www.springsource.org/node/3481">one for Europe</A>. Don't miss it!

Introduction

What is the Spring Integration Scala DSL?

The Spring Integration Scala DSL is a Domain Specific Language written in Scala with the goals of:

• providing a strongly-typed alternative to XML configuration for Spring Integration
• raising awareness about Spring Integration in Scala community
• providing first class integration with various Scala frameworks and products such as Akka
• providing seamless integration with Java where Scala developers can still leverage their existing Java investments

One thing we would like to point out is that the Spring Integration Scala DSL is not itself a new EIP framework. Rather, it's a Scala-based DSL that sits on top of the Java-based Spring Integration framework, and, in the first milestone, the DSL itself still relies heavily on Java types from the Spring Integration API. However, as it progresses through subsequent milestones, the DSL will evolve to become increasingly Scala-esque. We do believe that such close integration with the existing…

Welcome to another installment of This Week in Spring. We've got a lot of good stuff to look at, as usual.

  Since you&#39;re here, though, let&#39;s talk about the <a href="http://blog.cloudfoundry.com/post/13481010905/cloud-foundry-open-tour-2012" target="_blank">Cloud Foundry Open Tour</a>, which is an event bringing the industry&#39;s best talent and speakers on Spring, Cloud Foundry, and much more  to a town near you in America, Asia and Europe.  The full itinerary&#39;s provided on the linked page, but if you&#39;re in (or near) Shanhai, Beijing, Tokyo, London, Moscow, Kiev, San Francisco, Portland, Austin, and Washington D.C., then you should not  miss this event - <a href="http://opentour…

I am happy to announce that the first milestone release (1.0.0.M1) for Spring for Apache Hadoop project is available and talk about some of the work we have been doing over the last few months. Part of the Spring Data umbrella, Spring for Apache Hadoop provides support for developing applications based on Apache Hadoop technologies by leveraging the capabilities of the Spring ecosystem. Whether one is writing stand-alone, vanilla MapReduce applications, interacting with data from multiple data stores across the enterprise, or coordinating a complex workflow of HDFS, Pig, or Hive jobs, or…
