Craig Walls has posted a blog entitled Spring Integration:Return of the Bride of FileSucker Strikes Back...With a Vengeance. If it's not obvious enough from the title, the example demonstrates usage of the Spring Integration file-source adapter. It also highlights both the annotation-based model and the spring-integration namespace support. Craig provides all of the information and source code necessary to try out the sample for yourself. If you'd like to learn more after checking out Craig's blog, visit the Spring Integration Home.

Eivind Barstad Waaler has written an article about setting up scheduling in WebSphere using Spring and the CommonJ TimerManager API. The article is complete with a runnable example application and can be read here: Spring Scheduling in WebSphere

In this presentation from QCon San Francisco 2007, SpringSource CTO and AspectJ project lead Adrian Colyer discusses where Aspect-Oriented Programming (AOP) should be used, practical applications of AOP in enterprise situations such as Hibernate exception translation and automatic operation retry on nonfatal exceptions, and AOP mechanisms in Spring 2.5.

In this TheServerSide article, David Syer and Lucas Ward provide an overview of Spring Batch.

Interface21 have made available a new white paper on the topic of "Spring in Production." 

There's lots of documentation available on Spring's programming and configuration models, but very little written to date that explains what Spring does at runtime and how it manages the request processing pipeline. In this white paper you'll learn about the Spring kernel and the enterprise services layer that sits on top of it, and how these co-operate to manage Spring-powered applications. The white paper also contains a section on tuning Spring-powered applications. I asked many of my colleagues at Interface21 for their hints and tips on how to get the most out of a Spring-powered application in a production setting, and this priceless advice is distilled into over 25 recommendations and suggestions. In this part of the white paper you will:

• learn how to establish an effective blueprint for your application that takes full advantage of your deployment platform
• discover many tips for creating effective application designs in both OLTP and batch scenarios, and
• pick up some great ideas on exposing configuration data through JMX and for integrating statistics into your testing

I encourage you to download a copy of the white paper now and let us know what you think. Interface21 white papers are freely available, but we do ask that you register your interest first.

In this TSS article, Rod Johnson explains what Spring sets out to achieve and how it can help the community develop enterprise Java applications.

In this DevX article, Ramanujam A. Rao explains how to expose existing POJO-driven J2EE applications as web services using Axis2, showing the integration of Spring to facilitate the creation and control of these services.

Interested in a full-course of Spring during Winter? The Spring Experience 2007 conference is taking place in sunny Hollywood, Florida, from Dec. 12th-15th.

Tushar Joshi has authored an article titled "Introduction to Spring IDE 2.0". The article describes the required steps and dependencies to install Spring IDE and demos some basic features of version 2.0.

Tushar concludes his article by stating that: "Spring IDE provides features like Spring Explorer, Beans Cross Reference, Graph View and Code completion in the bean XML editor hence making the life of a Spring Framework user easier." #

In this infoQ interview recorded at The Spring Experience in December 2006, Spring Web Flow co-lead Keith Donald talks about how Spring Web Flow works, the abstractions modelled in Web Flow, support for the back button, continuations, how state is saved across web requests, how an existing app may be refactored to use web flows, and how Web Flow interact with web frameworks like Struts, Spring MVC, and JSF at runtime.
