The Web Process Designer sections
The Web Process Designer's UI contains four main sections: a toolbar at the top, Shape
Repository as an accordion panel on the left-hand side, an editing canvas at the center,
and a Properties panel as an accordion panel on the right-hand side of the editor. Let's ana-
lyze the main purpose of each one of these sections.
The toolbar
The toolbar is the topmost part of the designer panel; it contains different options to allow
us quick access to most of the features present in it as well as other useful options regard-
ing the layout of the process and its elements. The toolbar also has some other important
features that we are going to cover in this chapter, such as importing process definitions or
running simulations. So, feel free to play around with what's in the toolbar until you get
used to the options that you have and where they are.
The Shape Repository panel
The Shape Repository collapsible panel contains the palette of BPMN 2.0 elements used
to construct business processes. In this palette, you will find all of the BPMN 2.0 elements
(described in Chapter 3 , Using BPMN 2.0 to Model Business Scenarios ) grouped according
to their type. Sometimes, having all of the available elements in the palette is not the best
thing. After you have designed a couple of processes, you will notice that most of the time
you are using only a subset of these elements. This is why in the Shape Repository panel,
there are two different library sets: Full and Simple . You can switch from one perspective
to the other by using the drop-down list present at the top of the Shape Repository panel.
There is also a third option called RuleFlow , used to create files with the legacy descrip-
tion language for process definitions in jBPM6, but it is an outdated format that no longer
has support in the project, so we will skip it in this topic.
At the bottom section of the Shape Repository panel, we'll find the Workflow Patterns
panel with some predefined process flow structures to help you design your own processes
faster and in a standardized manner.
The editing canvas
The editing canvas is perhaps the most important part of the Web Process Designer. It is
where we are going to design our processes using the elements present in the Shape Re-
pository panel.
