10 Common Misconceptions About Spring

Engineering | Mark Fisher | August 04, 2006 | ...

Yesterday there were a few posts related to the forthcoming Beginning Spring 2 book, and I wanted to point those out here.

First, since this book will be of interest to those new to Spring - or even those who are simply curious at this point, we decided that it would be a good idea to include some discussion of common misconceptions about Spring. These have been posted here:
http://www.oreillynet.com/onjava/blog/2006/08/ten_common_misconceptions_abou.html
and on the Apress blog: http://ablog.apress.com/?p=1221.



Second, Interface21's Steven Devijver, the book's tireless lead author, has posted a great overview:
http://blog.interface21.com/main/2006/08/03/finishing-beginning-spring-2-from-novice-to-professional/.


The book, Beginning Spring 2: from Novice to Professional, will be in stores this October. While it aims to provide a gentle introduction appropriate for new Spring users, it will also be very useful for "filling in the gaps" even if you have been using the Spring Framework for a while. In other words, the book covers a lot of ground: the Spring container, AOP, data acess, MVC, and more. The coverage includes many new Spring 2.0 features - most notably an entire chapter exploring Spring's new and improved approach to AOP such as the XSD-based AOP namespace, integration with the AspectJ pointcut expression language, and @AspectJ integration! (Don't worry Spring 2 is backwards compatible - and the migration path is easy too). Throughout, the book provides a pragmatic balance of theory and examples. Those examples are backed by an interesting sample application (not overly simplistic). I personally was delighted when Steven asked me to contribute some exercises - yet another of his great ideas for providing an excellent resource to beginners. The first set of exercises walk through several techniques of dependency injection from basic wiring to the use of FactoryBeans and externalizing properties files. The second set of exercises are focused on AOP - including the new namespace and the @AspectJ style.

We are looking forward to an active companion site after the book's release, and of course you can continue to find many great discussions and examples of Spring 2.0 features here at the Interface21 team blog.

Finishing \"Beginning Spring 2: from Novice to Professional\"

Engineering | admin | August 03, 2006 | ...

To celebrate the launch of the new i21 team blog I take this opportunity to introduce a new Spring book that's coming up shortly. It's titled "Beginning Spring 2: from Novice to Professional" and is published by Apress. I've co-authored this book with Mark Fisher (i21), Bram Smeets (of DWR fame) and Seth Ladd (of "Expert Spring MVC and Web Flow" fame). Rob Harrop is the technical reviewer.

The book is targeted - as you might have guessed - to beginning users of the Spring Framework. Now the funny thing about Spring is that you're always a beginner in some areas. The framework offers so much…

AOP Configuration Choices in Spring 2.0

Engineering | Ben Hale | August 03, 2006 | ...

There are a lot of reasons to love working at Interface21, but by far the best has to be working with the leaders of the industry. For example, one of Spring 2.0's major focus points has been on improving AOP support. We've added a new configuration namespace, the AspectJ pointcut language and support for @AspectJ aspects. But this leaves a big question; what is the preferred way of writing Aspects in Spring 2.0? Since I'm an I21 employee, I have the luck of getting the answer straight from the horse's mouth.

I posited the question to Adrian Colyer, the Chief Scientist at Interface21 and…

Experience Spring in December in Hollywood, Florida

Engineering | Keith Donald | August 03, 2006 | ...

Over the last month Jay Zimmerman and I have been working hard planning The Spring Experience 2006 (TSE). Creating a first-class technical conference is no easy task--it takes hour upon hours to arrive at the perfect mix of speakers and content.

I am proud to say we are now ready to roll with an unprecedented event. Check it out:

The Spring Experience 2006

I hope to see you there. Here is what I believe sets this show apart:
  • 55 ninety-minute sessions across 5 tracks over 3-full days, all at a five-star beach resort.
  • Exclusive premium technical content on Spring 2.0. Half of the sessions are led by core Spring developers who apply the latest Spring capabilities inside and out. This includes Rod Johnson, Juergen Hoeller, Adrian Colyer, Rob Harrop, Colin Sampaleanu, Ben Alex, Arjen Poutsma, Erwin Vervaet, and yours truly.
  • Cutting edge sessions from leading Java software innovators. This includes Jeff McCaffer, lead of the Eclipse RCP and Equinox projects; Guilluame LaForge, Groovy project lead; Eamonn McManus, JMX Lead; Patrick Linskey, BEA Kodo JPA lead, and Mike Keith, lead of the Java Persistence Architecture (JPA).
  • Privileged access to synced-audio slideshows for all sessions following the show, so you don't miss a beat.
  • Full-course breakfast, lunch, and dinner included with registration.
  • "Meet the Gurus" user BOFs. A great opportunity for Spring users to interact with Spring project leads.
  • Two kick ass parties, one Friday night, and a Saturday afternoon party on the beach complete with a Spring users vs. developers volleyball game.
  • Cool conference schwag. And lots of it. Registered experiencers' receive an all access conference pass, a custom (and very cool) TSE laptop bag, a custom-designed notebook binder, a limited-edition TSE 2006 shirt, and even an official TSE 2006 beach towel. You'll have chances to win an iPod and XBox 360.
  • Diversity. Whether you are a hard core enterprise developer, a web application developer, or a leading software architect, this conference has something for you. Last year's show brought 250 people from 20 countries. This year we expect 500 attendees from over 25. It's going to be a lot of fun, and a great learning and networking opportunity.
There is no better place to be than Hollywood, Florida in December. See you and your team at The Spring Experience 2006!

What are you looking forward to in Spring 2.0?

Engineering | Ben Hale | August 02, 2006 | ...

Spring 2.0 is coming and I for one am excited. I can still remember the first time that I heard about all of the new features that would be in the release at last year's The Spring Experience. The asynchronous JMS message reception and the AOP integration with AspectJ excited me the most (a bit of drooling involved actually), but even then there were many other improvements and the list has only grown since.

Alas, I know that most of you aren't middle-tier nerds like me, so what are you excited about? The new XML dialects and XSD support? The improved JSP taglib? How about that <tx:annotation-driven />? Maybe you love that Groovy…

Sydney Spring User Group Meeting #2 Planned

In my last blog entry I promised to advise details of our next user group meeting. After hunting around for a suitable venue, it’s now organised for Monday 7 August 2006 at Cliftons, 200 George Street, Sydney. We have two presentations planned. First up I will be talking about Spring 2.0 namespaces, and then Ramon Buckland from Infocomp will be presenting SOA and JBI with Spring.Visit Springframework.org for full details.

Hope to see you there.

Getting Started With JPA in Spring 2.0

Engineering | Mark Fisher | May 30, 2006 | ...

The motivation behind this blog entry is to provide a simple step-by-step guide for getting started with JPA in a standalone environment with the Spring Framework. While the JPA specification originated as the persistence mechanism for EJB 3.0, it was fortunately recognized that any such mechanism should in fact be able to persist simple POJOs. Therefore, with a handful of JARs in your classpath and a few Spring-configured beans, you can begin experimenting with JPA code within your favorite IDE. I will be using Glassfish JPA - which is the reference implementation and is based upon Oracle's…

Atlanta DevCon 2006

Engineering | Ben Hale | May 26, 2006 | ...

I just got finished with my Spring 2.0: New and Noteworthy talk at Atlanta DevCon 2006. Let me be the first to say that the conference was great. The site and organizers were all top notch. I'd like to give a special shout-out to Burr Sutter for putting on one heck of a conference. You know that things are going well when the conference center doesn't have a wireless network but you can get the one from the cafe next door. That's good karma! The JUG members were all very knowledgeable (even the ones that didn't know about Spring) and asked great questions. I fielded questions about EJB…

Message Flow Tracing with AspectJ and JMX

Engineering | Ben Hale | April 25, 2006 | ...

In a project that I used to work on we had a system that would receive messages from a device and make decisions on whether that information would be passed to the user. There were multiple decision levels and one of the problems we always found ourselves asking was if a message was being lost on it's way through the system.

Before we moved to Spring, it was nearly impossible to tell the answer to that question. Attempts were made to use logging, but the sheer volume of messages that decisions were made on made it tedious at best. Other attempts were made using debuggers but a combination…
