CDI and Java EE Integration

The cibseven-engine-cdi and cibseven-engine-cdi-jakarta modules provide programming model integration with CDI (Context and Dependency Injection). CDI is the Jakarta EE/Java EE standard for Dependency Injection. The CIB seven CDI integration leverages both the configuration of the CIB seven 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 Jakarta EE, Java EE, and Java SE.
Support for unit testing.

Quarkus Engine Extension

Since Quarkus ArC does not aim to fully implement CDI 2.0, you cannot use the full range of features the cibseven-engine-cdi module provides. Read about the limitations in the Quarkus Integration guide.

Maven Dependency

To use the cibseven-engine-cdi module inside your application, you must include the following Maven dependency:

Please import the CIB seven BOM to ensure correct versions for every CIB seven project.

<dependency>
  <groupId>org.cibseven.bpm</groupId>
  <artifactId>cibseven-engine-cdi</artifactId>
</dependency>

For Jakarta EE 9+ containers, use the following dependency instead:

<dependency>
  <groupId>org.cibseven.bpm</groupId>
  <artifactId>cibseven-engine-cdi-jakarta</artifactId>
</dependency>

There is a project template for Maven called camunda-archetype-ejb-war, which gives you a complete running project, including CDI integration.
