Process modelling

We are going to describe the elements which define a jBPM process. A process is composed by:

• Nodes
• Transitions

To create a process definition in a graphical way, you can use jBPM Graphical Process Designer. This tool is packaged as a Eclipse plugin.

Nodes

The define the states of the process definition. They are connected by transitions. Both define the different path which can be followed in a running process definition. A running process definition is called process instance.

There are several types of nodes:

Start node

End node

Task node

Node node

State node

Decision node

Fork node

Join node
