What this book covers
Chapter 1, Installing and Getting Started with Bonita, starts off with installing the tool, Bonita Open Solution, and getting to know the various components of designing a workflow. It also shows an example of a simple process creation and getting it running. It finishes off by discussing the Bonita User Experience and administrative view options.
Chapter 2, Variable Types and Scopes, introduces the different variables that can be used in Bonita and discusses their scope. Instantiation and how different widgets use variables is also explored.
Chapter 3, Creating and Customizing Web Forms, explains the steps for creating a web form inside Bonita Studio by using the built-in widgets such as buttons, input boxes, messages, and many more. How the action buttons work is also explored in this chapter. In addition, conditional transitions from one step to the other have been introduced. By using all these elements, an example workflow application is initiated in this chapter.
Chapter 4, Conditions, Contingencies, and Transitions, covers the relation between different steps in the workflow. Message passing, call activity, and multi instantiation of a step are also discussed here. We show the JavaScript alternative to contingencies, too.
Chapter 5, Adding Connectors, looks at the various connector integration options available in Bonita Studio. We show how connectors can be used to fetch data into the workflow and how to export data, too. We have a close look at the Bonita inbuilt connectors, e-mail connectors, and database connectors, and also use them for the example application that we build. We get our example application almost functionally ready.
Chapter 6, Configuring the Page Flow, discusses the various options available for entry, view, and overview page flow. We discuss the various clickable features in the User XP and also have a look at the comments, attachments, and other sections that constitute the User XP. We also discuss the way to externalize web forms instead of creating them inside Bonita.
Chapter 7, Customizing Look and Feel, shows the various customization options in terms of the look and feel of the User XP and the web forms. We discuss the ways to edit and create a customized User XP and change the look of form elements.
Appendix, Deploying Bonita on a Server, details the steps that have to be followed to deploy BOS on a Tomcat server, changing the database connectors, and other configurations. It also explores the various Bonita APIs that are available and also has an example of a process using just APIs.
What you need for this book
The main software required to follow along with this book is Bonita Open Solution 5.10. There is a free version called the Community Edition and most features covered in this book can be used in the Community Edition. However, a few extra features that are available in the Subscription Pack (paid version) are also covered and workarounds have been suggested for the Community Edition. Bonita Open Solution has an inbuilt Groovy editor, due to which a separate IDE isn't required.
