Mr Spring, Rod Johnson, Speaking in Dublin March 11th

I’ve been lucky enough to have been using Spring for just over 4 years. If you don’t know what Spring is, it solves a lot of problems in complex Enterprise Java Systems. And it makes those systems more configurable; Spring makes your code like Lego blocks. Blocks that you can take apart and use again and again (no matter what the underlying technology is). And because you can take it apart, it makes your code easier to test. And testing is a good thing – the earlier you find bugs , the cheaper they are to fix.


Get the feeling that I’m a bit of a Spring fanatic? Wasn’t always that way. It took me two projects where other people had choosen Spring to convince me. And did I mention that it’s one of the most in demand skills in the Java world?

Rod Johnson (aka ‘Mr Spring’) is speaking in Dublin at the Westin hotel Dublin on the 11st March. It’s fairly central, and it’s a breakfast briefing, so you don’t even to have to arrange the day off work. More details on the event are on the Kainos Website.

Struts 2 is the new Mini

No matter what car you drive , the chances are it was influenced by the Mini. Introduced in the UK in the 1960’s a whole generation of families was crammed into a car that popularized the notion of front wheel drive. While small , it was practical and drove so well it even starred in films such as The Italian Job. Recently, a more modern version was released with none of the parts but all of the spirit of the Original.


We’ll come back to the Mini, but if you build websites using Java, then at some point you have used Struts. The original Struts is proof that a framework / project / product doesn’t have to be the best to be the most widely accepted. It just has to be in the right place at the right time, and ‘do what is says on the tin’ – in this case a fairly useful implementation of the ‘Model-View-Controller’ design pattern.

So what’s the link? Seeing the original Mini from the outside may bring a smile to your face, but on the inside it’s cramped and unfortable. You may have happy memories of websites you built using the original Struts, but lately your thoughts have been straying to more modern frameworks, perhaps with Ajax and integration with Spring built in.

This is where Struts 2 comes in. Like the Mini, it has (almost) none of the parts , but all of the Spirit of the original. It’s based on Webwork which sounds scary, but most Struts Drivers will be able to climb in , find the Struts.xml file and get the engine running within minutes. Struts 2 is easier to drive (JavaBeans instead of Action Forms), more powerful (it can use Ajax and JSF) and comes with more optional extras (e.g. it’s integration with other frameworks like Webwork and Spring).

Best of all the Struts team have a clear migration path between the old and new Struts. You can use both side by side in your garage application, and change over the parts piece by piece. Spare parts for the original Struts will still be available for quite some time, both from the original team and the large dealer developer network that has built up around the framework.

What do you think? When Are you going to give Struts 2 a try?
