The 3rd development milestone for Spring Integration 2.0 was released last week (download it here).

If you have read Oleg's recent blog, you already know that we have started working on a new reference sample implementation based on the "Loan Broker" example that plays a significant role in Gregor Hohpe and Bobby Woolf's Enterprise Integration Patterns book.

I just wanted to post a brief blog listing a few of the other new additions and improvements in this release. You can expect to see more detailed blog entries covering a few of these features over the next couple weeks. I'm including some…

We are pleased to announce the first installment of the 'Loan Broker' Reference Implementation. 'Loan Broker' concept has become a de-facto reference domain for showcasing Enterprise Integration Patterns (EIP) - by Gregor Hohpe ad Bobby Woolf, and this installment of the Loan Broker RI demonstrates how Enterprise Integration Patterns are realized and applied using Spring Integration (SI) framework.

Introduction

At the core of EIP architecture are the very simple yet powerful concepts of Pipes and Filters and Message. Endpoints (Filters) are connected with one another via Channels (Pipes). The producing endpoint sends Message to the Channel and the Message is retrieved by the Consuming endpoint.  This architecture is meant to define various mechanisms that describe How information is exchanged between the endpoints, without any awareness of What those endpoints are or What information they are exchanging, thus providing for a very …

Here in the Spring team, we are currently preparing for a busy next week: We have a three-day team meeting coming up from March 15th to 17th, immediately followed by the SpringSource S2G Forum Munich on Thursday, March 18th (overview, agenda, registration).

In the very near future, SpringSource tc Server 2.0™ will be released including a new Spring Edition, representing some big changes for the product and a big step ahead for web application development. This also continues SpringSource's commitment to tc Server being a 100% compatible drop-in replacement for Apache Tomcat that provides the best place to build and run your Spring applications and is ideally suited for modern virtual environments.

With the introduction of the security schema in Spring Security 2, it became much easier to get a simple secured application up and running. In older versions, users had to declare and wire-up all the implementation beans individually, resulting in large and complicated Spring application context files which were difficult to understand and maintain. There was a pretty steep learning curve and I can still remember that it took me some time to get my head round it all when I started working on the project (then Acegi Security), back in 2004. On the positive side, this exposure to the basic…

After two months of incorporating valuable feedback, it is my pleasure to announce the first Spring 3.0 maintenance release - addressing more than 170 reported issues. Get it from our download page.

There are some common concerns of users of Spring Batch and Spring Integration, and we get asked a lot about how they fit together. Spring Batch Admin 1.0.0.M2 was released recently, and it makes heavy use of Spring Integration, so it is a good vehicle for looking at some specific use cases, and that is what we plan to do in this article.

In my last entry, I walked you through several enhancements in Spring 3 for web application development. A number of you expressed interest in a follow-up entry focused on Ajax remoting. Spring 3 provides a lot in this area to take advantage of. Read on, and I'll walk you through it.

After our mad dash to the final release of Spring Roo 1.0.0 on New Year's Eve, many users have asked for an introductory screencast.

In this 5 minute screencast you will see how to:

• Develop a simple "contact manager application" using the Roo shell
• Import and edit the project our free IDE, SpringSource Tool Suite (STS)
• Run the Roo-provided integration tests in STS
• Modify the application and understand ITD round-trip support
• Deploy to your IDE's web container
• Use the scaffolded web user interface
• "Push-in refactor" to move source code between Java source files and ITDs
• Remove Roo from the project
