It's time to think about who or what you are going to be for halloween!

Welcome to another installation of This Week in Spring! I'm off to Oslo, Norway for the JavaZone conference to talk to people about using Spring Integration and Spring Batch on top of Cloud Foundry. Again, this is a natural use case: Cloud Foundry makes it easy to scale to handle the largest workloads, and Spring Integration and Spring Batch, presumably sitting on top of RabbitMQ, take care of the plumbing and do the heavy lifting of workload distribution across the cluster.

The video from VMWare engineer Jerry Kuch's webinar providing an update on the new features in RabbitMQ is also available. Finally, the video from the webinar that Ken Rimple, Srini Penchikala, and I did introducing how to more fully exploit Spring Roo's interactive add-on mechanism is available.

Remember, child contexts provide scoping - beans defined in one child can't see beans defined in another. This makes it very useful for things like Spring Batch Admin, which lets you upload and launch new Spring Batch jobs (which themselves are based on Spring configuration) on the fly. The Java Assist blog has a nice post on using Spring MVC bean validation in 3.0 or later. Cool! The Intelligrape blog has a quick post about using Grails' support for Spring beans, and exploiting Spring's lifecycle callbacks, particularly InitializingBean#afterPropertiesSet.

This week I'm in Bangalore, India with other members of the SpringSource and Cloud Foundry teams talking to major system integrators about Spring and Cloud Foundry. The uptake's amazing, and the feedback is even better. The new release features lots of new extension points in the Authorization Server features, a Whitelabel UI for better out-of-box experience, and improved support for expressions in security filters.
