Hi all!
First of all, thank you for this pretty framework. I’ve just started to use it and I love it!
I’ve read so many posts, faqs, tutorials and much more, but I’m still not able to keep my simple application with spring integrated working.
I’ve almost literally followed FAQ’s example at
Wiki
but when I run
mvn pckage tomcat7:run
the application is deployed successfully but accessing the main page a NullPointerException is raised at
bean.getLabel();
because the injection has not been made. It seems that all the configuration is good, but Spring does not inject the bean! How can it be? :wacko:
Thank you in advance, I hope someone can have good suggestions :*)

Here’s my code:
