CDI Tutorials

In this detailed Resource page, we feature an abundance of CDI Tutorials!

Contexts and Dependency Injection (CDI) for the Java EE platform is one of several Java EE 6 features that help to knit together the web tier and the transactional tier of the Java EE platform. CDI is a set of services that, used together, make it easy for developers to use enterprise beans along with JavaServer Faces technology in web applications. Designed for use with stateful objects, CDI also has many broader uses, allowing developers a great deal of flexibility to integrate various kinds of components in a loosely coupled but typesafe way.

CDI is specified by JSR 299, formerly known as Web Beans. Related specifications that CDI uses include the following:

JSR 330, Dependency Injection for Java

The Managed Beans specification, which is an offshoot of the Java EE 6 platform specification (JSR 316)

CDI Tutorials – Getting Started

Simple examples based on CDI for the Java EE platform

• Java EE CDI ConversationScoped example
  In this tutorial we shall show you how to create and use a ConversationScoped Bean in a web application.
• Java EE CDI Producer methods tutorial
  In this tutorial we will create a simple service with a Producer method to produce and inject our two implementations in an application.
