Even if jBPM6 uses BPMN 2.0, an XML-based standard, to define its processes, it's just not practical to write such files with a simple text editor. We need a way to define our process in a user-friendly environment that will aid both technical and non-technical people who know about the specifics of the steps involved in a process to define a process definition.
The BPMN 2.0 specification not only defines the behavior syntax for our processes, but also the look and feel for the process diagrams as well. This chapter will show you a step-by-step approach to learn how to use the jBPM6 Web Process Designer that lives inside the KIE Workbench to define BPMN 2.0 files using a diagram-writing UI. In this chapter, we will learn:
To define our processes
To test our processes with simulations
To extend the BPMN 2.0 model to add our own types of tasks
