Petite
Petite is one great little IoC container and components manager. Petite is easy to use since it requires no external configuration; it is incredibly fast, lightweight and super-small; so anyone can quickly grasp how it works. Petite is quite extensible and open for customization; and non-invasive.

find it and register as a bean. Or register it manually if you like that way more.
