CDI Articles

1. Configuration

In this tutorial you will learn how to configure Contexts and Dependency Injection (CDI) with Tomcat.
In this tutorial we will see how to deploy CDI beans contained in an external JAR file avoiding org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [...] with qualifiers [@...] at injection point ... exception.

2. Beans

In this tutorial you will learn in detail about the distinct bean scopes provided by CDI and how to use them.

In this tutorial you will learn how to inject multiple interface implementations with Java EE CDI (dependency disambiguation) avoiding org.jboss.weld.exceptions.DeploymentException: WELD-001409 Ambiguous dependencies for type [...] with qualifiers [...] at injection point [...]
In this tutorial we will see how to implement Java EE CDI dependency disambiguation in a programmatic (or dynamic) way by inspecting injection points. The same applies for programmatic dependency resolution at runtime.
In this tutorial we will see how to inject beans from external - or 3d party - libraries in Java EE CDI

4. Producers

In this tutorial you will learn how to use CDI Producer methods in order to provide a flexible bean initialization mechanism. Concepts like polymorphism, disambiguation and CDI scopes will also be discussed as we proceed in the tutorial.

5. CDI Extensions

In this article we will see how to programmatically add a CDI interceptor to a CDI managed bean.
In this article we will see how to implement a Java EE CDI portable extension from scratch. CDI extensions are used mainly by framework developers (ex: Apache DeltaSpike project, the former MyFaces CODI).
