The camunda-engine-cdi module provides programming model integration with CDI (Context and Dependency Injection). CDI is the Java EE 6 standard for Dependency Injection. The camunda-engine-cdi integration leverages both the configuration of the Camunda engine and the extensibility of CDI. The most prominent features are:

• A custom El-Resolver for resolving CDI beans (including EJBs) from the process,
• Support for @BusinessProcessScoped beans (CDI beans, the lifecycle of which are bound to a process instance),
• Declarative control over a process instance using annotations,
• The Process Engine is hooked-up to the CDI event bus,
• Works with both Java EE and Java SE,
• Support for unit testing.
