CDI tutorial links
DZone has a nice set of basic tutorials for CDI:
CDI part 1 covers @Inject, @Qualifier, @Singleton, and @NormalScoped.
CDI part 2 covers @Produces, @Observes, @Interceptor, @Decorator, and @Alternative.
For people like me who prefer small code examples to explanations, it’s a good overview, giving a quick feel for what programming with CDI is like.
