I'm a Spring newbie and recently completed the step by step guide which was very easy to follow, worked first time and it taught me the basics. The problem I have with it is that it's out of date and seems to be based on Spring 2.0, although claiming to be for 2.5.
Anyway, I downloaded Spring 3.0.1 got the tutorial app running on that and then set about updating it to conform with 3.0 which I believe I have achieved.
It's a shame that a guide so easy to follow for a beginner is not kept up to date.
So, I am willing to update the guide and post it here or somewhere else if anyone is interested.
