EIP 'Loan Broker' Reference Implementation (Part 1)

Engineering | Oleg Zhurakousky | March 18, 2010 | ...

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

lb-pipesFilters

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 …

Spring BlazeDS Integration 1.0.3 Released

Releases | Jeremy Grelle | March 12, 2010 | ...

Dear Spring Community,

I'm pleased to announce that the 1.0.3 maintenance release of Spring BlazeDS Integration, the open source solution for building Spring-powered RIAs with Adobe Flex, is now available.

Download | Reference Documentation | JavaDocs | Changelog

Along with a handfull of minor bug fixes targeting some of the new functionality added in 1.0.2, we have back-ported (from the in-progress 1.5M1) the few changes necessary for compatibility with the upcoming BlazeDS 4. This was done to provide the community with a stable release to use when exploring BlazeDS 4 without having to rely on nightly snapshots or milestone releases of Spring BlazeDS Integration 1.5.

As always, I encourage anyone interested to get involved by trying out the release and giving us feedback in the community forum and Jira. We continually get great feedback from people having success with Spring BlazeDS Integration in their projects, and we look forward to hearing more about your experiences.

Behind the Spring Security Namespace

Engineering | Luke Taylor | March 06, 2010 | ...

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…

Spring Framework 3.0.1 released

Engineering | Juergen Hoeller | February 18, 2010 | ...

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.

Since quite a few users asked for a dependencies distribution (as an alternative to grabbing dependencies via Maven or Ivy), we are providing a third download now: containing an Ivy repository with common third-party jar files. Note that the core framework is separate from the dependencies; the latter are just provided as an additional convenience and do not constitute an inherent part of the framework distribution. You may of course keep using any supported version…

Practical Use of Spring Batch and Spring Integration

Engineering | Dave Syer | February 15, 2010 | ...

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.

Spring Batch Integration

Part of the 1.0.0.M2 release was the Spring Batch Integration module, recently migrated from Spring Batch and given a new home with Batch Admin. Many of the Batch-Integration cross over use cases are either implemented or demonstrated in Spring Batch…
