Spring

Spring is probably one of the most talked about frameworks in Java. But you will probably never get a very clear answer what exactly it does!

This is because Spring is more or less an "umbrella" project which does several things - more and more each day.

It provides a Dependency Injection and Session Beans management framework, an MVC framework, Hibernate and JMS integration, Security infrastructure, Cloud support, etc, etc

Many of these components have nothing to do with each other.

We will try and use each of these Spring frameworks, starting with the Dependency Injection.
