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.

As datacenters virtualize more and more workloads, it becomes important to understand the potential impact on the Java servers that may be running your applications. At SpringOne 2GX 2011, Ben Corrie provided a thorough overview of Java memory management, how things work differently in virtual environments and what you can do about it to avoid problems. This includes a practical introduction to Elastic Memory for Java (EM4J) that is a feature of the VMware vFabric platform.

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.

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.

If you missed the recent Cloud Foundry webinar that covered Spring development, you can catch the video replay on the Cloud Foundry YouTube channel.
