Another session from SpringOne 2GX 2011 gives a detailed guide to Identity Management with Spring Security. Spring developer and also Cloud Foundry engineer, Dave Syer, covers Single Sign On, security standards (including SAML, OpenID, OAuth, SCIM, JWT), how Spring Security can fit in, as well as demoing identity management as a service. Dave has tackled some of the most complex problems possible in enterprise Java and this presentation provides a great guide for developers interested in security identity in distributed environments.

Many thanks to InfoQ for coming to Chicago to record so many of the fantastic SpringOne 2GX presentations.

Welcome to another installment of This Week in Spring. Lot's of good content to go over, this week, so let's get to it.

Also: if you're in Stockholm, Sweden attending the JFokus Java conference, be sure to stop by the VMWare booth to say hi or have your questions answered about Spring, Cloud Foundry, and vFabric.

1. Alan Stewart has announced the release of Spring Roo 1.2.1, which includes fixes for multi-module Maven projects, huge performance enhancements, and updated support for PrimeFaces 3.1 and Google App Engine 1.6.2.

   <LI> Oliver Gierke has announced that <a href = "http://www.springsource.org/node/3469">JPA 1.1.0 RC1 and 1.0.3 GA have been released</a>. Among the many new features, the release includes support for locking, 
   	 <code>@IdClass</code> in entities,
   	Support for <code>LessThanEqual</code> and  <code>GreaterThanEquals</code>, <code>True</code>/<code>False</code> keywords in query methods…

If you missed the recent Cloud Foundry webinar that covered Spring development, you can catch the video replay on the Cloud Foundry YouTube channel. In this video, Ramnivas Laddad shows you how to take a real Spring application and target it to Cloud Foundry using both STS and the vmc command line.

Be sure to thumbs up the presentation if you find it useful and subscribe to the SpringSourceDev channel to see other recordings and screencasts.

On the way to Spring IO conference I'd like to announce the availability of Spring Data MongoDB 1.0.1. It's mainly a bug fix release covering a few glitches found in the first major release. We've fixed some issues in entity mapping, query execution and added a converter for UUIDs out of the box.

Downloads | JavaDocs | Reference Documentation | Changelog

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.

The Spring Roo team is pleased to announce the availability 1.2.1.RELEASE.  This is the first maintenance release for 1.2 and includes fixes for a number of issues in multi-module Maven support and JSF/PrimeFaces.  It also has  performance enhancements and has been updated to support the recent release of PrimeFaces 3.1 and Google App Engine 1.6.2.

Please note that to keep the distribution size small we have not included the reference documentation in the zip for this and future releases. The documentation, as always,  can be found on the Spring Roo site.

Dear Spring Community,

I am happy to announce the release of Spring Data JPA 1.1.0 RC1 as well as 1.0.3 GA. The release candidate includes a ton of new features and a variety of bug fixes. Here's a brief list of the most important ones:

• Support for locking
• Support for @IdClass in entities
• Support for LessThanEqual and GreaterThanEquals, True/False keywords in query methods
• Added CDI integration for repositories
• Improved parameter binding for derived queries for null values

The CDI integration was contributed by Dirk Mahler of Buschmais to a large degree. For a full list of changes see the changelog. Quite a few of the bugs fixed were back ported so we definitely recommend to upgrade to 1.0.3 as well as playing with the release candidate to help improving the final release. The 1.0.3 GA release can be obtained from Maven central while the release candidate is available via our milestone repository at http://repo.springsource.org/libs-milestone…

Welcome to another installment of This Week in Spring . As usual, a lot to look at, so let's get to it.

<LI> The <a href="http://www.springsource.org/spring-mobile/news/1.0.0.rc1-released" target="_blank">1.0.0.RC1 version of Spring Mobile</a> has just been released. Spring Mobile provides an integration API that makes it easier for Spring MVC applications to build mobile client-specific applications.

<LI> Chris Richardson&#39;s talk, <a href="http://www.springsource.org/node/3463" target="_blank"><EM>Polyglot Persistence for Java Developers</EM></a>, has just been released. This is another great talk from SpringOne2GX, and  a good watch for anybody who wants a look at how to exploit…

Dear Spring Community,

We are pleased to announce that the first release candidate of the Spring Mobile project is now available!

Spring Mobile provides extensions to Spring MVC that aid in the development of cross-platform mobile web applications. The 1.0.0.RC1 release ships a general facility for user site preference management that can be used independently or in conjunction with the mobile site switcher. See the changelog and reference manual for all the info.

Download the release distribution or pull the artifacts from Maven using the following:

    <repository>
        <id>org.springframework.maven.milestone</id>
        <name>Spring Maven Milestone Repository</name>
        <url>http://maven.springframework.org/milestone</url>
    </repository>
&lt;dependency&gt;
    &lt;groupId&gt;org.springframework.mobile&lt;/groupId&gt;
    &lt;artifactId&gt;spring-mobile-device&lt;/artifactId&gt;
    &lt;version&gt;1.0.0.RC1&lt;/version&gt;
&lt;/dependency&gt;

Get sample apps over at github.com/SpringSource/spring-mobile-samples | git clone git://github.com/SpringSource/spring-mobile-samples.git

This release marks our fifth iteration with early adopters in the community using Spring Mobile in their own applications. If you are building a mobile web app, we encourage you try out 1.0.0.RC1 and collaborate with us on the next iteration of the project.

In another session from SpringOne 2GX 2011 SpringSource engineer Stephen Bohlen examines Spring and Platform Interoperability. Stephen analyzes different approaches to Java and .NET interoperability, discusses how Spring can help and then provides a detailed sample application that expresses some of the best practices. Stephen's work on the Spring.NET project gives him the perfect perspective on how to address these sorts of problems.

Many thanks to InfoQ for coming to Chicago to record so many of the fantastic SpringOne 2GX presentations.
