Get started Developing Process Applications with Jakarta EE

This tutorial guides you through your first steps developing an EximeeBPMS process application on top of Jakarta EE: JSF for the user interface, CDI for dependency injection and process variable access, JPA for persistence, and an EJB service bean invoked from the process.

Target Audience: In this tutorial we assume that you are familiar with the basics of Jakarta EE application development, and that you have installed an Eclipse (or comparable IDE) distribution, the Camunda Modeler, and a WildFly application server.

You will be guided through the following steps:

Project Setup: Set up a Jakarta EE process application as an Apache Maven Project.
Process Application: Declare the process archive, persistence unit, and enable CDI and JSF for the application.
Model & Start Form: Model the pizza order process with the Camunda Modeler and add a JSF start form.
EJB Service Task: Add a JPA entity and an EJB service bean that persists the order via a BPMN service task.
User Task Forms: Add JSF user task forms to approve an order and prepare the pizza, with a CDI-scoped controller.
Complete the Process: Wire up the rejection e-mail service task to complete the process.
